1. Wind and rain replaced flowers. If it rains and winds, the flowers should rest.
2. The rain was cold all night and turned into a dream. Qiu Lai was given a lotus leaf.
3. Cold rain enters Wu day and night, and sees Fujian off in Chu.
The hometown is introduced as follows:
Hometown refers to the place where you were born or lived for a long time. For the second meaning, it is generally called "second hometown". In ancient China, there were many elegant names in hometown, such as Sang Zi, Jiashan and the old country.
Rain is introduced as follows:
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. Water vapor rises to a certain height and becomes small water droplets after cooling. 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.
The mechanism of rain is introduced as follows:
How did these small water droplets increase their volume to more than 654.38+00,000 times? It mainly relies on two means, one is condensation and sublimation. The second is to rely on the collision and increase of cloud droplets. In the initial stage of raindrop formation, cloud droplets mainly condense and condense themselves by constantly absorbing water vapor around the cloud. If the water vapor in the cloud can be continuously replenished and replenished.
If the surface of cloud drops is always in a state of supersaturation, then this condensation process will continue, making the cloud drops grow and become raindrops. However, sometimes the water vapor content in the cloud is limited, and in the same cloud, the water vapor is often in short supply, so it is impossible to make every cloud droplet grow into a larger raindrop, and some smaller cloud droplets have to be merged into a larger cloud droplet.
