Rain usually occurs in four forms:
1. Front rain (plum rain): Warm and humid air from the ocean meets cold air from the land. Because cold air is heavy and warm air is light, warm and humid air is forced to rise and condense when it is cold, forming a long and wide rain belt. This is frontal rain.
2. Convective rain: In summer, under the strong sunlight, the warm and humid air in some areas rises sharply, and it condenses when it meets cold to form rain. This is convective rain, which is called "thunderstorm" in meteorology, and we usually call it "explosion". In addition, typhoon rain is also a kind of convective rain.
3. Topographic precipitation: Warm and humid air from the ocean is forced to rise when it meets mountains, and condenses when it meets cold, resulting in rainfall.
4. Typhoon storm: The hot and humid air on the tropical ocean surface rotates and rises strongly in a large range. In the process of rising, the temperature drops rapidly, and a large amount of water vapor condenses into clouds and rain, which is typhoon rain.
The water drops falling from the clouds and the water on the land and sea surface evaporate into steam. When the steam rises to a certain height, it becomes small water drops when it is cold. These small water droplets form a cloud, where they collide with each other and merge into large water droplets. When it is too big for the air, it will fall from the clouds and form rain.
Rain is the most important fresh water resource in human life, and plants thrive on the moisture of rain and dew. But the flood caused by rainstorm will also bring great disaster to mankind.
