spring rain
"Delighting in Rain on a Spring Night" Don Du Fu: Good rain knows the season, when spring comes. Sneak into the night with the wind, moisten things silently. The wild path is dark, and the river is bright. Look at the red and wet place, the flowers in Jinguancheng are heavy.
Yu Xia
Song Zhou Bangyan in Heji: Ji, Xia Feng and Harmony. There are many cicadas in high willows. Small garden, terrace, far pool waves. Fish play with new lotus flowers. Yarn kitchen, light feather fan, cold pillow and deep courtyard. The mood at this time is this time, and it is nothing for the gods.
autumn rain
Yin Mingtang: Plum blossoms are cut, pear blossoms are beaten by rain, doors are closed, and youth is forgotten and missed. Pleasure * * * Who said that? Flowers are charming, and the moon is charming. Sorrow gathers eyebrows, and a thousand tears mark ten thousand tears marks. See the sky at dawn and the clouds at dusk. When I walk, I miss you; Even when I am sitting, I miss you.
Winter rain
Don Justin Cheung, Rain in the South of the Yangtze River: There is almost no chill on the river, but in the winter months, the rain still flies. When you go out, you worry about listening, and the wind scatters your clothes. The traveler's soul is broken, but the hometown letter is slightly smaller. It should clear up in a few days. I want to go home alone.
Data expansion:
Rain, a natural precipitation phenomenon, is caused by the disturbance of atmospheric circulation, is an indispensable part of the earth's water cycle, and is the only way for almost all terrestrial plants far from rivers to replenish fresh water. Raindrops fall from the sky, big and small, fast and slow. The water on the earth's surface evaporates and rises, and it cools to form rain. Rainwater is the most important fresh water resource in human life.
Rain is water drops falling from the clouds. Water on land and sea surface evaporates into water vapor. When water vapor rises to a certain height, it becomes small water droplets when it is cold. These small water droplets form a cloud, where they collide with each other and merge into large water droplets.
When it is too big for the air, it falls from the clouds and forms rain. Rain is the most important fresh water resource in human life, and plants thrive on the moisture of rain and dew. But the flood caused by rainstorm will also bring great disaster to mankind.
Front 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 is cold, forming a long and wide rainfall belt. This is the rain before.
