Why are there so many stars at night that it will rain the next day? !

There are many stars at night, which means there are few clouds in the sky. The next day, there was no necessary condition for rain. Where can it come from?

Observing the stars also requires good weather conditions. Many times we want to go to the mountains to see the stars, and we also need corresponding conditions: it can't rain, it can't be cloudy, the visibility must be good, and there is no smoke? Only under better conditions can we see many stars.

With the development of industry, bright stars can no longer be seen in many parts of the city?

When there are no clouds at night, the visibility will be relatively better. Without the cover of clouds, all the stars can fall from the sky, and we can see countless stars. When there is no cloud, even if the temperature drops the next day, the water vapor in the cloud will not condense into small drops and fall to the ground, forming rainfall.

You know, all our rain comes from clouds. When the water on the ground and in the ocean evaporates into the air and becomes steam, it will gather and condense into clouds when the air is cold. When the cloud formed by these small water droplets keeps gathering and getting bigger, it will get heavier and heavier, so heavy that the air can't support it, and it will fall from the air.

But some clouds are big, some clouds are small, some places have fast temperature changes, and some places have high wind speed. Under the influence of different factors, what we see on the ground are different rain conditions: heavy rain, light rain and sudden rainstorm?

Of course, a cloudy day doesn't mean it will rain. In many cases, it only brings cloudy weather, which blocks some sunlight and radiation on the ground, so that the temperature on the ground will rise and fall more smoothly.

So sometimes, we can judge the weather by observing the sky, such as a starry night, and the next day is usually sunny, so we need to be prepared for shading. For example, if it is cloudy, it may rain, so you need to prepare rain gear. Of course, there are many kinds of weather like this. Don't go out at sunrise, but go to Wan Li Road at sunset? Wait?
