1. rainfall

   Rain is water droplets that have condensed from atmospheric water vapor and then 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 water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. 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 (28.1 in), but over the whole Earth it is much higher at 990 mm (39 in). 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.

1. rainfall

   Rainfall is the falling of condensed water droplets from the atmosphere to the Earth's surface, usually as a result of the condensation of atmospheric water vapor during certain climatic processes. This natural meteorological phenomenon is essential for replenishing water sources, maintaining the planet's climate, and supporting the growth of plants and survival of living organisms.

Examples of Rainfall in a Sentence

1. Hazrat Mir:

   For October, this has been the worst rainfall we have seen for at least 30 years.

2. Marty Ralph:

   An atmospheric river marked as a category 4 or a 5 is capable of producing remarkable rainfall totals over three or more days, likely to exceed 10 % to 15 % of a typical year's precipitation in some locations.

3. David Feldman:

   There's good documentation that, in fact, there is less rainfall. What seems to be happening according to most of the climate scientists is we're getting longer, drier periods, but the irony is those longer, drier periods are punctuated by very intense storm events.

4. Liz Bentley:

   It's going to continue into the autumn and then really, we don't know beyond that. It depends on whether we see any significant rainfall -- good steady rainfall that replenishes water levels, what we don't want at the moment are heavy, thundery downpours, because the ground is so dry that water just runs off. It doesn't soak into the ground.

5. Kyle Tapley:

   Some areas that have already seen a little too much rainfall are going to get some more.
