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 brush your face. The feeling is gentle, like a mother gently touching your face, very comfortable. And the grass and flowers will become more colorful with the nourishment of spring rain. Spring rain is their nutrition.
Summer rain is the most passionate. The rain hit the eaves, and the glass made a "squeaking" sound, which made people think that Xia Yu was like a crazy bee that kept buzzing. The feeling of being hit in the face by Xia Yu was not good. It hurts like a small stone thrown into the face.
Autumn rain is a combination of spring rain and summer rain. Sometimes the autumn rain sweeps over the earth in thin lines, and sometimes it is like hair. Falling like a roar. However, the autumn rain is the messenger of harvest fruits. The farmer uncle feels much more relaxed because the harvest day is here.
The rain in winter is like a rain in ancient times. Women rarely show up. If it rains in winter, it is probably snow. At this time, the children are happy and can have fun again: < /p>
Rain usually appears in four forms:
1. Frontal rain (Meiyu): The warm and moist airflow from the ocean meets the cold air from the land. Because the cold air is heavy, the warm air Light, warm and moist airflow is forced to rise, condenses when encountering cold, and forms a very long and wide rainfall belt. This is frontal rain.
2. Convection rain: In summer, under strong sunlight, local areas experience rain. Warm and moist air rises sharply and condenses when it encounters cold, forming rainfall. This is convective rain. In meteorology, it is called "thunderstorm", but we usually call it "blasting rain". In addition, typhoon rain is also a type of convective rain.
3. Orographic rain: Warm and moist air from the ocean encounters mountains, is forced to rise, and condenses when encountering cold, forming rainfall.
4. Typhoon rain: hot and humid air on the tropical ocean surface. The scale violently rotates and rises. During the rise, the temperature drops rapidly and a large amount of water vapor condenses into clouds and rain. This is typhoon rain.
