Why doesn t it rain together, but it rains regularly and little by little

The rain in the sky comes from the clouds in the sky, and the clouds in the sky are actually condensates of water, which come from the evaporation of water vapor from the ground. When the water droplets in the cloud reach a certain level, that is, they cannot be supported by the rising air current, the water droplets will fall to the ground, which is what we see as rain. Evaporation of water vapor can occur at any time, but not rain all the time.

In the air, when the temperature is high, the amount of water vapor that can be held is large, and when the temperature is low, the amount of water vapor that can be held in the air is less. When the weight of the water droplets exceeds the buoyancy of the air, it has a certain weight, attracted by the attraction of the earth, and there is no way to stop in the air anymore, it will fall, and it will form rain. Such as:

In the afternoon of summer, due to the strong evaporation, rise, condensation, and formation of showers; Frontal rain formed by the southward movement of cold air and the hot and humid air flow from the southeast, and so on. As rivers, rivers, lakes, and seas are exposed to the sun, water becomes water vapor. The water vapor rises and turns into small water droplets or Xiaoice crystals, and the air flow below is constantly transporting the water vapor to the clouds.

The small water droplets and Xiaoice crystals in the cloud collide with each other in motion, and the volume will increase. The water droplets in the lower layer of the cloud slowly get larger, and as the volume of the ice crystals in the upper layer of the cloud increases, they fall between the droplets in the lower part of the cloud, and the water droplets become larger and larger. When these droplets are so big that the updrafts can't hold them back, it rains.

There are many aspects to this question, including meteorology, physics, etc. To put it simply, rain does not fall all together, but in regular waves, due to the influence of water vapor and air movement in the clouds.

First, we know that clouds are formed by the condensation of water vapor in the atmosphere. Clouds are formed when the water vapor in the air reaches saturation. Water droplets or ice crystals in clouds are called cloud droplets, and cloud droplets gather with each other to form raindrops.

Secondly, air movement also has an effect on the formation of clouds and rain. When warm, moist air rises, it cools and forms clouds. If the air continues to rise, the water droplets in the clouds will condense into water or ice, forming raindrops.

Finally, in the process of falling, raindrops are affected by air resistance and gravity, causing them not to fall together. In addition, the size and shape of the raindrops also affect how fast they fall.

To sum up, the rain does not fall all together, but in regular waves, which is due to the influence of water vapor and air flow in the clouds.

The continuous drizzle kept falling, like a beaded curtain between heaven and earth, and like a gentle veil covering everything in the world.

Tolerance, like a timely drizzle, can moisten the dry fields of the heart.

In this spring season, the slanting wind and drizzle, the grass color from afar, how pleasant it should be!
