It can be divided into: light rain, moderate rain, heavy rain, heavy rain, heavy rain, heavy rain, heavy rain, heavy rain, light snow, medium snow, heavy snow and blizzard. Instead of what some people think, it is heavy rain when it is urgent, and light rain when it is slow.
According to the regulations of China Meteorological Bureau, the rainfall within 24 hours is called daily rainfall, and any daily rainfall below10mm is called light rain,10.0-24.9mm is moderate rain, 25.0-49.9mm is heavy rain, 50.0-99.9mm is rainstorm, and100.0-250.
In addition, showers or thunderstorms that are often heard in summer belong to the order of light rain. In order to classify precipitation levels in more detail, small to moderate rain, moderate to heavy rain and heavy rain are often used in weather forecast.
