A severe thunderstorm watch has been lifted after being in place for most of the country. [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. [35][36], The METAR code for rain is RA, while the coding for rain showers is SHRA.[37]. [53] Savanna climates and areas with monsoon regimes have wet summers and dry winters. Oregonians are probably chanting “rain, rain, go away!” today as a winter storm dumps more than 2 inches of percipitation on the valley floor and more than 4 inches at higher elevations, according to National Weather Service predictions. [59] Areas in their path can receive a year's worth of rainfall from a tropical cyclone passage. [16] Water vapor normally begins to condense on condensation nuclei such as dust, ice, and salt in order to form clouds.

[123] Rain may be harvested through the use of rainwater tanks; treated to potable use or for non-potable use indoors or for irrigation. 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. [102] For instance, river flood control, sewer management and dam construction are all areas where planners use rainfall accumulation data. 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. The extent of rainbands around a tropical cyclone can help determine the cyclone's intensity. Walker S. Ashley, Thomas L. Mote, P. Grady Dixon, Sharon L. Trotter, Emily J. Powell, Joshua D.

Tropical cyclone rainbands contain showers and thunderstorms that, together with the eyewall and the eye, constitute a hurricane or tropical storm. Rainfall rates downwind of cities are increased between 48% and 116%. − [120] Plants need varying amounts of rainfall to survive. [2][3] The amount of moisture in air is also commonly reported as relative humidity; which is the percentage of the total water vapor air can hold at a particular air temperature. Air resistance typically causes the water droplets in a cloud to remain stationary. He said he wondered whether the tarseal on the roads would lift when the flooding eased, as it had in the February flood. Global warming is also causing changes in the precipitation pattern globally, including wetter conditions across eastern North America and drier conditions in the tropics. Elita Chikwati.

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. 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. Re: heavy rains, a heavy rain Well actually to be correct you should say: "The runoff from heavy rains washed away the bridge." “As more debris continues to hit the log jam the impact is felt through the entire structure and the water level will need to drop before equipment can be brought in to begin to clear this.”. / [142] Within Asia, rainfall is favored across its southern portion from India east and northeast across the Philippines and southern China into Japan due to the monsoon advecting moisture primarily from the Indian Ocean into the region. In temperate climates, people tend to be more stressed when the weather is unstable or cloudy, with its impact greater on men than women. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. Avoid flushing non-flushable items down the toilet. d 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. [1] Climate classification systems such as the Köppen classification system use average annual rainfall to help differentiate between differing climate regimes.

Llazar Semini contributed … [139], The northern half of Africa is occupied by the world's most extensive hot, dry region, the Sahara Desert. [174] Accordingly, research carried out by the European Southern Observatory shows that WASP-76b can produce showers of burning liquid iron droplets once temperature decreases during the planet's night hours. India Meteorological Department (IMD) said that heavy rains and wind are likely to … [25], Rain drops associated with melting hail tend to be larger than other rain drops. 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. Most precipitation in the tropics appears to be convective; however, it has been suggested that stratiform precipitation also occurs. No detour was available and drivers were asked to avoid the area. A common biome in this area is the tundra which has a short summer thaw and a long frozen winter. In the right conditions, some plants may recover with the rain hindering plant development. A radar equation is then used, which is. "Significant Weather – December 2000 (Rainfall)", "New Wettest Location for U.S.A. Heavy rain is causing widespread flooding, landslides and road washouts in Haines. The highest recorded rainfall in a single year was 22,987 mm (905.0 in) in 1861.

[86], An oceanic (or maritime) climate is typically found along the west coasts at the middle latitudes of all the world's continents, bordering cool oceans, as well as southeastern Australia, and is accompanied by plentiful precipitation year-round. [64], Analysis of 65 years of United States of America rainfall records show the lower 48 states have an increase in heavy downpours since 1950. [111] The term 1 in 10 year storm describes a rainfall event which is unusual and has a 50% chance of occurring in any 10-year period. Precipitation, especially rain, has a dramatic effect on agriculture. [39] What separates rainfall from other precipitation types, such as ice pellets and snow, is the presence of a thick layer of air aloft which is above the melting point of water, which melts the frozen precipitation well before it reaches the ground. [7] The air can rise due to convection, large-scale atmospheric motions, or a physical barrier such as a mountain (orographic lift). A detour was available. Dark clouds over Timaru on Sunday afternoon. The five primary classifications can be further divided into secondary classifications such as rain forest, monsoon, tropical savanna, humid subtropical, humid continental, oceanic climate, Mediterranean climate, steppe, subarctic climate, tundra, polar ice cap, and desert.
