关于降雨的英语论文？
Rain is a kind of liquid water, which is condensed by atmospheric water vapor. It becomes heavy enough under the action of gravity. It is a major part of the water cycle, responsible for precipitation of most of the fresh water on the earth.
It provides suitable conditions for many types of eco. Besides the water used for hydropower plants and crop irrigation, the main reason for rain water generation is that the water content along the If there is enough moisture and upward movement, it is called weather front. Precipitation falls from cumulonimbus (clouds with strong vertical upward movement), such as cumulonimbus (thunderstorm), which can be organized into narrow rain belts in mountainous areas.
In the windward side of the terrain at altitude, the uphill airflow is the largest, forcing the moist air to condense and fall off, and then heavy precipitation may occur. As the rainfall along the mountain side of the leeward side of the mountains, the dry air caused by the downhill airflow causes the air quality to be heated and dried, so the desert climate may exist. The movement of the monsoon trough or tropical convergence zone brings the rainy season to the prairie region.

雨是一种液态水，是由大气水汽凝结而成的液态水，在重力作用下变得足够重，它是水循环的一个主要组成部分，负责将地球上的大部分淡水沉淀下来，它为许多类型的生态系统提供了适宜的条件，除了水力发电厂和作物灌溉用水外，雨水产生的主要原因是水分沿着温度和湿度的三维区域移动，如果存在足够的水分和向上运动，则称为天气锋，降水从积雨云（具有强烈垂直向上运动的云层）落下，如积雨云（雷云），在山区可以组织成狭窄的雨带。在海拔高度的地形迎风面内，上坡气流最大，迫使潮湿空气凝结并脱落，则可能出现强降水由于降雨沿着山脉背风侧的山侧，由于下坡气流引起的干燥空气导致空气质量的加热和干燥，因此可能存在沙漠气候。季风槽或热带辐合带的移动将雨季带到大草原地区。
