Rain <=SEP=> Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then precipitated -- that is , become heavy enough to fall under gravity . Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth . It provides suitable conditions for many types of ecosystems , as well as water for hydroelectric power plants and crop irrigation .   The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts . 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 . In mountainous areas , heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains . On the leeward side of mountains , desert climates can exist due to the dry air caused by downslope flow which causes heating and drying of the air mass . The movement of the monsoon trough , or intertropical convergence zone , brings rainy seasons to savannah climes .   The urban heat island effect leads to increased rainfall , both in amounts and intensity , downwind of cities . Global warming is also causing changes in the precipitation pattern globally , including wetter conditions across eastern North America and drier conditions in the tropics . Antarctica is the driest continent . The globally averaged annual precipitation over land is 715 mm , but over the whole Earth it is much higher at 990 mm . Climate classification systems such as the Köppen classification system use average annual rainfall to help differentiate between differing climate regimes . Rainfall is measured using rain gauges . Rainfall amounts can be estimated by weather radar .   Rain is also known or suspected on other planets , where it may be composed of methane , neon , sulfuric acid , or even iron rather than water .

Supercell <=SEP=> A supercell is a thunderstorm characterized by the presence of a mesocyclone : a deep , persistently rotating updraft . For this reason , these storms are sometimes referred to as rotating thunderstorms . Of the four classifications of thunderstorms ( supercell , squall line , multi-cell , and single-cell ) , supercells are the overall least common and have the potential to be the most severe . Supercells are often isolated from other thunderstorms , and can dominate the local weather up to 32 km away .   Supercells are often put into three classification types : Classic , Low-precipitation ( LP ) , and High-precipitation ( HP ) . LP supercells are usually found in climates that are more arid , such as the high plains of the United States , and HP supercells are most often found in moist climates . Supercells can occur anywhere in the world under the right pre-existing weather conditions , but they are most common in the Great Plains of the United States in an area known as Tornado Alley and in the Tornado Corridor of Argentina , Uruguay and southern Brazil .

Tropical cyclone <=SEP=> A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center , a closed low-level atmospheric circulation , strong winds , and a spiral arrangement of thunderstorms that produce heavy rain . Depending on its location and strength , a tropical cyclone is referred to by names such as hurricane ( -LSB- ˈhʌrᵻkən -RSB- or -LSB- ˈhʌrᵻkeɪn -RSB- ) , typhoon -LSB- taɪ ` fuːn -RSB- , tropical storm , cyclonic storm , tropical depression , and simply cyclone . A hurricane is a storm that occurs in the Atlantic Ocean and northeastern Pacific Ocean , a typhoon occurs in the northwestern Pacific Ocean , and a cyclone occurs in the south Pacific or Indian Ocean .   Tropical cyclones typically form over large bodies of relatively warm water . They derive their energy through the evaporation of water from the ocean surface , which ultimately recondenses into clouds and rain when moist air rises and cools to saturation . This energy source differs from that of mid-latitude cyclonic storms , such as nor'easter s and European windstorms , which are fueled primarily by horizontal temperature contrasts . The strong rotating winds of a tropical cyclone are a result of the conservation of angular momentum imparted by the Earth 's rotation as air flows inwards toward the axis of rotation . As a result , they rarely form within 5 ° of the equator . Tropical cyclones are typically between 100 and in diameter .   Tropical refers to the geographical origin of these systems , which form almost exclusively over tropical seas . Cyclone refers to their cyclonic nature , with wind blowing counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere . The opposite direction of circulation is due to the Coriolis effect .   In addition to strong winds and rain , tropical cyclones are capable of generating high waves , damaging storm surge , and tornadoes . They typically weaken rapidly over land where they are cut off from their primary energy source . For this reason , coastal regions are particularly vulnerable to damage from a tropical cyclone as compared to inland regions . Heavy rains , however , can cause significant flooding inland , and storm surges can produce extensive coastal flooding up to 40 km from the coastline . Though their effects on human populations are often devastating , tropical cyclones can relieve drought conditions . They also carry heat energy away from the tropics and transport it toward temperate latitudes , which may play an important role in modulating regional and global climate .

Climate of India <=SEP=> The climate of India comprises a wide range of weather conditions across a vast geographic scale and varied topography , making generalisations difficult . Based on the Köppen system , India hosts six major climatic subtypes , ranging from arid desert in the west , alpine tundra and glaciers in the north , and humid tropical regions supporting rainforests in the southwest and the island territories . Many regions have starkly different microclimates . The nation has four seasons : winter ( December , January and February ) , summer ( March , April and May ) , a monsoon rainy season ( June to September ) , and a post-monsoon period ( October to November ) .   India 's geography and geology are climatically pivotal : the Thar Desert in the northwest and the Himalayas in the north work in tandem to effect a culturally and economically important monsoonal regime . As Earth 's highest and most massive mountain range , the Himalayas bar the influx of frigid katabatic winds from the icy Tibetan Plateau and northerly Central Asia . Most of North India is thus kept warm or is only mildly chilly or cold during winter ; the same thermal dam keeps most regions in India hot in summer .   Though the Tropic of Cancer -- the boundary between the tropics and subtropics -- passes through the middle of India , the bulk of the country can be regarded as climatically tropical . As in much of the tropics , monsoonal and other weather patterns in India can be wildly unstable : epochal droughts , floods , cyclones , and other natural disasters are sporadic , but have displaced or ended millions of human lives . There is one scientific opinion which states that in South Asia such climatic events are likely to change in unpredictability , frequency , and severity . Ongoing and future vegetative changes and current sea level rises and the attendant inundation of India 's low-lying coastal areas are other impacts , current or predicted , that are attributable to global warming .

Uruguay <=SEP=> Uruguay ( -LSB- ˈjʊərəɡwaɪ -RSB- -LSB- uɾuˈɣwai̯ -RSB- ) , officially the Oriental Republic of Uruguay ( República Oriental del Uruguay ) , is a sovereign State in the southeastern region of South America . It borders Argentina to its west and Brazil to its north and east , with the Río de la Plata ( River of Silver ) to the south and the Atlantic Ocean to the southeast . Uruguay is home to an estimated 3.42 million people , of whom 1.8 million live in the metropolitan area of its capital and largest city , Montevideo . With an area of approximately 176000 km2 , Uruguay is geographically the second-smallest nation in South America , only larger in size than Suriname .   Uruguay was inhabited by the Charrúa people for approximately 4000 years before the Portuguese established Colonia del Sacramento , one of the oldest European settlements in the region , in 1680 . Montevideo was founded as a military stronghold by the Spanish in the early 18th century , signifying the competing claims over the region . Uruguay won its independence between 1811 and 1828 , following a four-way struggle between Spain , Portugal , Argentina and Brazil . It remained subject to foreign influence and intervention throughout the 19th century , with the military playing a recurring role in domestic politics until the late 20th century . Modern Uruguay is a democratic constitutional republic , with a president who serves as both head of state and head of government .   Uruguay is ranked first in Latin America in democracy , peace , lack of corruption , e-government , and is first in South America when it comes to press freedom , size of the middle class and prosperity . On a per-capita basis , Uruguay contributes more troops to United Nations peace-keeping missions than any other country . It ranks second in the region on economic freedom , income equality , per-capita income and inflows of FDI . Uruguay is the third-best country on the continent in terms of HDI , GDP growth , innovation and infrastructure . It is regarded as a high-income country ( top group ) by the UN . Uruguay is also the third-best ranked in the world in e-Participation .  Uruguay is an important global exporter of combed wool , rice , soybeans , frozen beef , malt and milk . Nearly 95 % of Uruguay 's electricity comes from renewable energy , mostly hydroelectric facilities and wind parks .   The Economist named Uruguay `` country of the year '' in 2013 , acknowledging the innovative policy of legalizing the production , sale and consumption of cannabis . Same-sex marriage and abortion are also legal , leading Uruguay to be regarded as one of the most progressive nations in the world , and one of the most socially developed , outstanding regionally , and ranking highly on global measures of personal rights , tolerance , and inclusion issues .
