Will it rain in summer?

It rains in summer solar terms, which generally means that there is no shortage of rain behind and drought is not easy to occur. But if it doesn't rain in summer and solar terms, it's hard to say There may be less rain in autumn and less rain in winter. In many rural areas, there is indeed a saying that "it rains a lot in summer", and some places even sum it up as an agricultural proverb.

For example, "the sun rises in summer and the fish die in autumn", which means that the weather is fine on the day of the summer solar term, indicating that there is less rain in autumn and the possibility of drought is high. In addition, there are "eighteen rivers with rain in summer and rivers without rain in summer", which means that all rivers will rise when it rains in summer and there is more rain behind. When it doesn't rain in summer, even rivers will dry up.

Rain usually occurs in four forms:

1, before the rain (plum rain)

Warm and humid air from the ocean meets cold air from the land. Because the cold air is heavy and the warm air is light, the warm and humid airflow is forced to rise and condense when it is cold, forming a long and wide rain belt, which is frontal rain.

2. Convective rain

In summer, under the strong sunlight, the warm and humid air in some areas rises sharply, condenses when it meets cold, and forms rainfall. This is convective rain, which is called "thunderstorm" in meteorology, and we usually call it "sky 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, forming 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.
