Characteristics of spring rain, summer rain, autumn rain and winter rain:

Spring rain is the softest. If the spring rain comes, you try to let the rain wipe your face. That feeling is gentle, just like mom touching your face gently, which is very comfortable. The grass and flowers will be more colorful with the spring rain. Spring rain is their nourishment.

Summer rain is the most passionate. The rain hit the eaves, and the glass made a "Hua La" sound, which made people think that Xia Yu was like a crazy bee, constantly chirping. The taste of being hit in the face by summer rain is not good. It hurts like a small stone thrown in the face.

Autumn rain is a combination of spring rain and summer rain. Sometimes the autumn rain sweeps across the earth, but sometimes it falls like a wheeze. However, autumn rain is the messenger of harvest fruit. After the autumn rain, the farmer's uncle felt much more relaxed, because the harvest day has arrived.

The rain in winter, like an ancient woman, rarely shows up. If it rains in winter, it's probably snow. It fluttered in the sky. At this time, the children are happy and can have a good time again. :

Rain usually appears in four forms:

1. Frontal rain (plum rain): The warm and humid airflow from the ocean meets the 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 meets the cold, forming a long and wide rainfall belt, which is frontal rain.

2. Convective rain: In summer, under the strong sunlight, the warm and humid air in some areas rises sharply, and when it is cold, it condenses and forms rainfall. This is called 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. orographic 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 on a large scale. 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.
