The equatorial region is dominated by convective rain all year round (the strongest convection is around 2 pm), and convective rain in China is more common in summer afternoon. (2) Topographic precipitation: When wet air moves horizontally, it encounters high mountains and "climbs" along the hillside, and the temperature drops and water vapor condenses. The precipitation formed on the windward slope of the mountain range is called topographic precipitation. Windward slopes in coastal areas, rivers along lakes and other wet places (such as the southern slope of Himalayas, Huoshaoliao in Taiwan Province Province, etc.). (3) Frontal rain: When cold and warm air meet, relatively light warm air is "lifted", and the precipitation produced by cold condensation is called frontal rain. At the junction of land and sea, such as the eastern coastal areas of China (4) Typhoon storm: a cyclone formed on the tropical ocean surface (rotating upward).
