# extreme rainfall wikipedia

For the mathematical pseudonym, see. A radar equation is then used, which is. [48] The Sierra Nevada range creates the same effect in North America forming the Great Basin and Mojave Deserts.[49][50]. This may take place over one day or a … Return period - An estimate of the average time interval between occurrences of an event (e.g., flood or extreme rainfall) of a defined size or intensity. Extreme precipitation events have produced more rain and become more common since the 1950s in many regions of the world, including much of the United States. [143] The monsoon trough can reach as far north as the 40th parallel in East Asia during August before moving southward thereafter. Edmonton has a fairly dry climate. Coalescence occurs when water droplets fuse to create larger water droplets. The climate of Uttar Pradesh (U.P.) [108] All plants need at least some water to survive, therefore rain (being the most effective means of watering) is important to agriculture. [60], The fine particulate matter produced by car exhaust and other human sources of pollution forms cloud condensation nuclei, leads to the production of clouds and increases the likelihood of rain. Given the Earth's surface area, that means the globally averaged annual precipitation is 990 millimetres (39 in). Scatter charts kendo ui for angular. Both tropical and temperate rainforests exist. ", "Global Measured Extremes of Temperature and Precipitation", "Tutunendaó, Choco: la ciudad colombiana es muy lluviosa", "Global Measured Extremes of Temperature and Precipitation#Highest Average Annual Precipitation Extremes", "Diamond Rain May Fill Skies of Jupiter and Saturn", "It rains solid diamonds on Uranus and Neptune", "Highlights of the Galileo Probe Mass Spectrometer Investigation", "On a Faraway Planet, it's Cloudy With a Chance of Liquid Iron Rain", "Finding distant chips from distant maria", "UFL – Dispute between Mawsynram and Cherrapunji for the rainiest place in the world", BBC article on the mathematics of running in the rain, https://en.wikipedia.org/w/index.php?title=Rain&oldid=997899195, Short description is different from Wikidata, Wikipedia indefinitely semi-protected pages, Wikipedia indefinitely move-protected pages, Creative Commons Attribution-ShareAlike License, Light rain — when the precipitation rate is < 2.5 mm (0.098 in) per hour, Moderate rain — when the precipitation rate is between 2.5 mm (0.098 in) - 7.6 mm (0.30 in) or 10 mm (0.39 in) per hour. Air resistance typically causes the water droplets in a cloud to remain stationary. Rainforests are also responsible for 28% of the world's oxygen turnover. There, a normal year would be called extreme in many other parts of the world, with many stations regularly receiving more than 100 mm/dy on the wettest day of the year, especially on the southern coast (Figure 3). Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. The extent of rainbands around a tropical cyclone can help determine the cyclone's intensity. Occluded fronts usually form around mature low-pressure areas. It has the highest average annual rainfall on Earth, with 460 inches (12,000 mm) per year. Thare is an absence o extreme temperatures an a cuil breeze due tae the tred winds frae the Atlantic Ocean. Around 40–75% of all biotic life is found in rainforests. Photo by Abhishek N. Chinnappa. [38][42] Graupel and hail indicate convection. Westerly flow from the mild north Atlantic leads to wetness across western Europe, in particular Ireland and the United Kingdom, where the western coasts can receive between 1,000 mm (39 in), at sea level and 2,500 mm (98 in), on the mountains of rain per year. Adiabatic cooling occurs when air rises and expands. Terrain is considered in QPFs by use of topography or based upon climatological precipitation patterns from observations with fine detail. Many communities are It falls as showers with rapidly changing intensity. {\displaystyle d} In heavily populated areas that are near the coast, such as the United States' Eastern Seaboard, the effect can be dramatic: there is a 22% higher chance of rain on Saturdays than on Mondays. When noted on weather radar imagery, this precipitation elongation is referred to as banded structure. Walker S. Ashley, Thomas L. Mote, P. Grady Dixon, Sharon L. Trotter, Emily J. Powell, Joshua D. Durkee, and Andrew J. Grundstein. Some health impacts of climate change are already being felt in the United States. Precipitation can fall in either liquid or solid phases, or transition between them at the freezing level. Cloud Formation Processes", "Fog And Stratus – Meteorological Physical Background", "Cloud Physics: Collision/Coalescence; The Bergeron Process", "Bad Meteorology: Raindrops are shaped like teardrops", "Single-drop fragmentation distribution of raindrops", "An ingredients based methodology for forecasting precipitation associated with MCS's", "Rainstorm characteristics affecting water availability for agriculture", "Stratiform Precipitation in Regions of Convection: A Meteorological Paradox? The IMERG analysis from June 20 through 26, 2016 showed that extreme rainfall that fell over the western United States from Jan. 17 to 24, 2017. Rain chart. The globally averaged annual precipitation over land is 715 mm (28.1 in), but over the whole Earth it is much higher at 990 mm (39 in). Extreme rainfall—defined as the top five percent of rainy days—often forms a pattern at the local level, for example tracking across … . [23][29] The parameters are somewhat temperature-dependent,[30] and the slope also scales with the rate of rainfall [123] Rain may be harvested through the use of rainwater tanks; treated to potable use or for non-potable use indoors or for irrigation. "La Nina could mean dry summer in Midwest and Plains". d [139], The northern half of Africa is occupied by the world's most extensive hot, dry region, the Sahara Desert. [162] Storms in Chocó can drop 500 mm (20 in) of rainfall in a day. As these larger water droplets descend, coalescence continues, so that drops become heavy enough to overcome air resistance and fall as rain. [65][66], The most successful attempts at influencing weather involve cloud seeding, which include techniques used to increase winter precipitation over mountains and suppress hail. [84] The humid subtropical climate zone is where winter rainfall is associated with large storms that the westerlies steer from west to east. D For example, certain cacti require small amounts of water,[121] while tropical plants may need up to hundreds of inches of rain per year to survive. 0 Stratiform (a broad shield of precipitation with a relatively similar intensity) and dynamic precipitation (convective precipitation which is showery in nature with large changes in intensity over short distances) occur as a consequence of slow ascent of air in synoptic systems (on the order of cm/s), such as in the vicinity of cold fronts and near and poleward of surface warm fronts. The record-breaking rain fell in just 10 hours. This extra heat leads to greater upward motion, which can induce additional shower and thunderstorm activity. It can also form due to the lifting of advection fog during breezy conditions.[19]. Various skill scores can be determined to measure the value of the rainfall forecast.[118]. Destin| Given the current record season, thus far, August look out you must turned out to be surprisingly but happily just above average, in terms of named storms. [40] Hail becomes an increasingly infrequent occurrence when the freezing level within the atmosphere exceeds 3,400 m (11,000 ft) above ground level. per unit volume of space is ⟨ [27] Animals have adaptation and survival strategies for the wetter regime. Precipitation is measured using a rain gauge, and more recently remote sensing techniques such as weather radar. The stories shared on the map show how global warming is affecting our lives as individuals. The most commonly used form of the Köppen classification has five primary types labeled A through E. Specifically, the primary types are A, tropical; B, dry; C, mild mid-latitude; D, cold mid-latitude; and E, polar. The wet season is a time when air quality improves,[55] freshwater quality improves,[56][57] and vegetation grows significantly. Over the contiguous United States, total annual precipitation increased at an average rate of 6.1 percent since 1900, with the greatest increases within the East North Central climate region (11.6 percent per century) and the South (11.1 percent). Precipitation is a major component of the water cycle, and is responsible for depositing most of the fresh water on the planet.Approximately 505,000 km 3 (121,000 mi 3) of water falls as precipitation each year, 398,000 km 3 (95,000 cu mi) of it over the oceans. rainfall extremes and suggests that the three-parameter extreme value distribution of type II is a choice closer to reality and easy to use even with short rainfall records. Precipitation occurs when local air becomes saturated with water vapor, and can no longer maintain the level of water vapor in gaseous form. This generally requires more mass than coalescence when occurring between the crystal and neighboring water droplets. Froland is a municipality in Aust-Agder county, Norway. e An extreme rainfall event is defined as one in which precipitation over some specified time period exceeds some threshold, either at a point (i.e., as measured by a single rain gauge) or in an average over some spatial region. [22][23] Contrary to popular belief, their shape does not resemble a teardrop. [78], The phrase acid rain was first used by Scottish chemist Robert Augus Smith in 1852. The previous dry season leads to food shortages into the wet season, as the crops have yet to mature. This process is temperature dependent, as supercooled water droplets only exist in a cloud that is below freezing. [114] Starting in the mid to late 1990s, QPFs were used within hydrologic forecast models to simulate impact to rivers throughout the United States. {\displaystyle \langle d\rangle ^{-1}=41R^{-0.21}} In South America, the Andes mountain range blocks Pacific moisture that arrives in that continent, resulting in a desertlike climate just downwind across western Argentina. In Botswana, the Setswana word for rain, pula, is used as the name of the national currency, in recognition of the economic importance of rain in its country, since it has a desert climate. In dry places, such as India,[127] or during periods of drought,[128] rain lifts people's moods. When classified according to the rate of precipitation, rain can be divided into categories. Heavy rain describes rainfall with a precipitation rate above 7.6 millimetres (0.30 in) per hour. Rainfall totals from the storm are expected to range from a half-inch to an inch. 2015.. flasher; flash in the pan; Look at other dictionaries: flash flood — noun count a sudden unexpected flood … — noun count a sudden unexpected flood … Scientists show that devastating increases in extreme rainfall over the last 30 years fit in with global temperature rise caused by greenhouse gases. This is commonly referred to as the Marshall–Palmer law after the researchers who first characterized it. Moisture is removed by orographic lift, leaving drier air (see Foehn) on the descending (generally warming), leeward side where a rain shadow is observed.[6]. Photo by Abhishek N. Chinnappa. [1] Climate classification systems such as the Köppen classification system use average annual rainfall to help differentiate between differing climate regimes. An observation study of island effect bands: precipitation producers in Southern California. The dew point is the temperature to which a parcel must be cooled in order to become saturated. [90], Rain is measured in units of length per unit time, typically in millimeters per hour,[91] or in countries where imperial units are more common, inches per hour. In the past 20 years the concentrations of nitric and sulfuric acid has decreased in presence of rainwater, which may be due to the significant increase in ammonium (most likely as ammonia from livestock production), which acts as a buffer in acid rain and raises the pH.[81]. Karasburg haes an extreme climate maist times o the year wi temperatures risin tae 48 degrees celsius in the rainy saison an droppin tae 2 degrees in the dry saison. August Look Out You Must 2020 Hurricane Summary. BASIC CONCEPTS OF EXTREME VALUE DISTRIBUTIONS It is recalled from probability theory that, given a number nof independent identically New Zealand's mountains tend to modify and amplify precipitation, and this often causes the frequent heavy rainfall we experience. Heavy rain describes rainfall with a precipitation rate above 7.6 millimetres (0.30 in) per hour. 41 The heaviest rain is seen in reds and yellows. Recife haes a tropical forest. [6], There are four main mechanisms for cooling the air to its dew point: adiabatic cooling, conductive cooling, radiational cooling, and evaporative cooling. After the inner cylinder is filled, the amount inside it is discarded, then filled with the remaining rainfall in the outer cylinder until all the fluid in the outer cylinder is gone, adding to the overall total until the outer cylinder is empty. Tropical rainforests technically do not have dry or wet seasons, since their rainfall is equally distributed through the year. Tropical cyclones, a source of very heavy rainfall, consist of large air masses several hundred miles across with low pressure at the centre and with winds blowing inward towards the centre in either a clockwise direction (southern hemisphere) or counter clockwise (northern hemisphere). This is caused by a convergence zone that lies over the southern part of Japan and the adjoining oceans. Large rain drops become increasingly flattened on the bottom, like hamburger buns; very large ones are shaped like parachutes. Its poleward progression is accelerated by the onset of the summer monsoon which is characterized by the development of lower air pressure (a thermal low) over the warmest part of Asia. Climate change in Brazil is the changes in Brazil's climate due to human caused global warming. The term 1 in 100 year storm describes a rainfall event which is rare and which will occur with a 50% probability in any 100-year period. Svg wikimedia commons. Radar-derived rainfall estimates complement surface station data which can be used for calibration. Rainfall events from a major storm or hurricane, or intense localised downpours can lead to flooding in any type of location. Abbs (1999) recommended that increased effort be placed on numerical modelling of extreme rainfall events. Extreme events related to heat and rainfall are easier to study than extremes related to fires, droughts, or tornadoes. The forecasts can be verified through use of rain gauge measurements, weather radar estimates, or a combination of both. Climate Extremes Index (CEI) was developed to quantify observed changes in climate within the contiguous United States. The intensity can also be expressed by rainfall erosivity R-factor[109] or in terms of the rainfall time-structure n-index. ( One of the main uses of weather radar is to be able to assess the amount of precipitations fallen over large basins for hydrological purposes. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. − Rainfall rates downwind of cities are increased between 48% and 116%. d [99][100] If a network is not available in the area where one lives, the nearest local weather or met office will likely be interested in the measurement.[101]. [27][28], The final droplet size distribution is an exponential distribution. [136] Given the Earth's surface area, that means the globally averaged annual precipitation is 990 mm (39 in). Some 1.825 meters (71.8 inches) of rain … [92] The "length", or more accurately, "depth" being measured is the depth of rain water that would accumulate on a flat, horizontal and impermeable surface during a given amount of time, typically an hour. Satellite derived rainfall estimates use passive microwave instruments aboard polar orbiting as well as geostationary weather satellites to indirectly measure rainfall rates. Rain forests are characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1,750 and 2,000 mm (69 and 79 in). [170][171] On Titan, Saturn's largest natural satellite, infrequent methane rain is thought to carve the moon's numerous surface channels. Left: Rainfall estimated from satellite data (GPM/IMERG, mm/dy) on 6 … Rain forests are characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1,750 and 2,000 mm (69 and 79 in). [58] Although cyclones can take an enormous toll in lives and personal property, they may be important factors in the precipitation regimes of places they impact, as they may bring much-needed precipitation to otherwise dry regions. A Climatological and composite study of cold season banded precipitation in the Northeast United States. Extreme Rainfall Location Maximum Daily Rainfall (mm) Date British Columbia Ucluelet 489 1967-10 Yukon Quiet Lake 91 1972-7 Alberta Eckville 213 1970-6 Northwest Territories Fort Liard 100 1986-7 Saskatchewan Cypress Hill 193 1998-6 Nunavut Coral Harbour 128 1973-10 Manitoba Rivers Riding Mountain Park 239* (awaiting confirmation) 217 2020-6 1975-9 "What is a TROWAL? A Bow Echo and Severe Weather Associated with a Kona Low in Hawaii. [105], The likelihood or probability of an event with a specified intensity and duration, is called the return period or frequency. To produce radar accumulations, rain rates over a point are estimated by using the value of reflectivity data at individual grid points. [133] The Akkadians believed that the clouds were the breasts of Anu's consort Antu[133] and that rain was milk from her breasts. [146][147] During the summer, the Southwest monsoon combined with Gulf of California and Gulf of Mexico moisture moving around the subtropical ridge in the Atlantic Ocean bring the promise of afternoon and evening thunderstorms to the southern tier of the United States as well as the Great Plains. 20 examples: At least in 1998, the exit of butterflies from overwintering sites was… The U.S. They are widespread on Africa, and are also found in India, the northern parts of South America, Malaysia, and Australia. A wide variety of weather can be found along an occluded front, but usually their passage is associated with a drying of the air mass. Moisture is removed by orographic lift, leaving drier air (see katabatic wind) on the descending and generally warming, leeward side where a rain shadow is observed. 3: Water in the Atmosphere", "Quantitative Precipitation Forecast: Its Generation and Verification at the Southeast River Forecast Center", "Optimization of quantitative precipitation forecast time horizons used in river forecasts", "Sensitivity of quantitative precipitation forecast to height dependent changes in humidity", "Probabilistic Quantitative Precipitation Forecast for Flood Prediction: An Application", "Quantitative Precipitation Forecast (QPF) from Weather Prediction Models and Radar Nowcasts, and Atmospheric Hydrological Modelling for Flood Simulation", "The significance of socio-economic characteristics for adult seasonal body-weight fluctuations: a study in north-western Benin", "Harvesting, Storing, and Treating Rainwater for Domestic Indoor Use", "The effect of weather on mood, productivity, and frequency of emotional crisis in a temperate continental climate", "Sudden spell of rain lifts mood in Delhi", "Praying for rain: the intersection of weather and religion", "Precipitation of the Individual States and of the Conterminous States", "Monsoon, Orography, and Human Influence on Asian Rainfall", "Chapter-II Monsoon-2004: Onset, Advancement and Circulation Features". [120] Plants need varying amounts of rainfall to survive. n Weather Centre – World Weather – Country Guides – Northern Mariana Islands. [113] A QPF will be specified when a measurable precipitation type reaching a minimum threshold is forecast for any hour during a QPF valid period. If sea breeze rainbands become active enough just ahead of a cold front, they can mask the location of the cold front itself. Heavy snowfall describes conditions when visibility is restricted below .5 kilometres (0.31 mi).[12]. Extreme weather The sound of a heavy rain fall in suburban neighborhood, CS1 maint: multiple names: authors list (. A case is presented for esti-mating return periods given different rainfall intensity for a station in Upper Manoa, Oahu. The highest rainfall of 620 millimetres (24 in) was recorded in Islamabad in 24 hours on 23 July 2001. (open, save, copy) sacbee.com. The storm dropped moderate rainfall across much of the southern United States. [7] Storm systems affect the region with heavy rains between October and March. Since then rainfall has increased again in the regions, inevitable making rainfall look “more extreme”. The front creates the portion of an occluded cyclone known as its comma head, due to the comma-like shape of the mid-tropospheric cloudiness that accompanies the feature. ⟩ [67], Rainbands are cloud and precipitation areas which are significantly elongated. Extreme weather events are especially damaging to agriculture. Convective rain and light precipitation are the result of convective clouds, for example cumulonimbus or cumulus congestus. They can be subdivided into: The parenthesized letters are the METAR codes for each phenomenon.[1]. Most of Brazil has moderate rainfall of between 1,000 and 1,500 millimetres (39 and 59 in) a year, most of it coming between December and April. With unusually severe rainfall in India's financial capital Mumbai over the past few weeks, and severe drought conditions elsewhere in the country, questions are … The longer these conditions persist in the same place, the more extreme the rainfall you’re likely to have. (d in centimeters and R in millimeters per hour). Elevated portions of weather fronts (which are three-dimensional in nature)[17] force broad areas of upward motion within the Earth's atmosphere which form clouds decks such as altostratus or cirrostratus. The biggest rainfall in a day occurred with the passage of Cyclone Denise in Foc-Foc, La Réunion, an island in the southern Indian Ocean. via the Internet Wayback Machine". Cloud Formation Processes. [115] Forecast models show significant sensitivity to humidity levels within the planetary boundary layer, or in the lowest levels of the atmosphere, which decreases with height. The administrative center is the village of Blakstad, which along with Osedalen form the main population center of the municipality. In practice, the definition of an extreme rainfall event varies widely. Ireland's climate is defined as a temperate oceanic climate, or Cfb on the Köppen climate classification system, a classification it shares with most of northwest Europe. > So "extreme weather" is indicated by more air conditioners and less umbrellas being sold ? [73] Bands of thunderstorms can form with sea breeze and land breeze boundaries, if enough moisture is present. [11] Snowfall intensity is classified in terms of visibility . Climate change has played an important role in causing large-scale floods across central India, especially the Mumbai floods of 2005. [32], Rain falling on loosely packed material such as newly fallen ash can produce dimples that can be fossilized, called raindrop impressions. Heatwave. [23], Raindrops impact at their terminal velocity, which is greater for larger drops due to their larger mass to drag ratio. The administrative center of the municipality is the town of Grimstad. [31] The distribution has an upper limit due to droplet fragmentation. [148] Over the top of the ridge, the jet stream brings a summer precipitation maximum to the Great Lakes. Smaller drops are called cloud droplets, and their shape is spherical. The wet, or rainy, season is the time of year, covering one or more months, when most of the average annual rainfall in a region falls. {\displaystyle n(d)=n_{0}e^{-d/\langle d\rangle }dD} In meteorology, the various types of precipitation often include the character or phase of the precipitation which is falling to ground level. − The extreme rainfall was caused by a strong south-westerly flow bringing moisture from the subtropics and convergence over southwestern Japan, the mechanism also described by Imada et al, 2013. Partly as a result of this warming, monthly rainfall is about 28% greater between 32 to 64 km (20 to 40 mi) downwind of cities, compared with upwind. නම - name ("ශ්‍රී ලංකා ප්‍රජාතාන්තික සමාජවාදී ජනරජය" එහි නිලනාමය වෙයි) ‍මේ ගැන මටනම් සැකයි හොදින් ඒ ගැන දන්නා අයෙක් එ … Stratiform precipitation occurs when large air masses rise diagonally as larger-scale atmospheric dynamics force them to move over each other. [135] In the present-day United States, various state governors have held Days of Prayer for rain, including the Days of Prayer for Rain in the State of Texas in 2011. The large size is explained by condensation on large smoke particles or by collisions between drops in small regions with particularly high content of liquid water. [132] Rainmaking rituals are also important in many African cultures. ", "2005 Tropical Eastern North Pacific Hurricane Outlook", "Background: California's tropical storms", "NASA Satellite Confirms Urban Heat Islands Increase Rainfall Around Cities", United States Environmental Protection Agency, "Across U.S., Heaviest Downpours On The Rise | Climate Central", "Planned and Inadvertent Weather Modification". Record rainfall extremes in the UK over 200 mm in 24 hours, based on data from the British Rainfall publication, 1866-1968 and other sources. Observed maximum bending moment data on gumbel probability. 16. n [16] Water vapor normally begins to condense on condensation nuclei such as dust, ice, and salt in order to form clouds. Convection occurs when the Earth's surface, especially within a conditionally unstable or moist atmosphere, becomes heated more than its surroundings and in turn leading to significant evaporation. A tropical savanna is a grassland biome located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes , with rainfall between 750 and 1,270 mm (30 and 50 in) a year. The probability plot correlation coefficient test for the normal, log. As a raindrop increases in size, its shape becomes more oblate, with its largest cross-section facing the oncoming airflow. The warm air overrides the cooler air and moves upward dud . Best-fit probability distributions and return periods for maximum. Moderate rain describes rainfall with a precipitation rate of between 2.6 millimetres (0.10 in) and 7.6 millimetres (0.30 in) per hour. [89] Subarctic climates are cold with continuous permafrost and little precipitation. Extreme rainfall -- defined as the top five percent of rainy days -- often forms a pattern at the local level, for example tracking across … Tropical cyclone rainbands contain showers and thunderstorms that, together with the eyewall and the eye, constitute a hurricane or tropical storm. [25], Rain drops associated with melting hail tend to be larger than other rain drops. Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then become heavy enough to fall under gravity. [124] Excessive rain during short periods of time can cause flash floods. Rainforests are areas of the world with very high rainfall. Scientists expect these trends to continue as the planet continues to warm. Although extreme weather has been part of the meteorological system for millions of years, climate change is making our weather more extreme, more frequently, in ways never before seen in human history. The lift of the air up the side of the mountain results in adiabatic cooling, and ultimately condensation and precipitation. Precipitation falls in many forms, or phases. File:gumbel probability paper. 97-37 November 21, 1997: El Niño and California Precipitation. Tulane University.Retrieved June 5, 2013, from http://www.tulane.edu/~sanelson/Natural_Disasters/riverflooding.htm These places are of course only too delighted. [117] Radar imagery forecasting techniques show higher skill than model forecasts within 6 to 7 hours of the time of the radar image. When the visibility is over 1 kilometre (0.62 mi), snow is determined to be light. Antarctica is the driest continent. [98], When a precipitation measurement is made, various networks exist across the United States and elsewhere where rainfall measurements can be submitted through the Internet, such as CoCoRAHS or GLOBE. For the Halloween ﬂood in 2004, the estimated return period is approximately 27 … [76] Behind extratropical cyclones during fall and winter, rainbands can form downwind of relative warm bodies of water such as the Great Lakes. Weekly temp and rainfall record sheet by rainbowdrop86 teaching. (open, save, copy) en.wikipedia.org. [80] Rain becomes acidic primarily due to the presence of two strong acids, sulfuric acid (H2SO4) and nitric acid (HNO3). Cherrapunji, situated on the southern slopes of the Eastern Himalaya in Shillong, India is the confirmed wettest place on Earth, with an average annual rainfall of 11,430 mm (450 in).
