Why does the weather in Chengdu alternate regularly between hot and cold recently?

This is a very simple truth, which you should have learned in middle school.

You can often see the moon at night recently. I wonder if you have noticed. Seeing the moon means there are not many clouds in the sky. Clouds can reflect infrared rays and keep warm, so if there are clouds at night, the temperature will not drop too much. The temperature will be higher the next morning.

Sichuan is a basin, and Chengdu is a plain part in the middle of the basin. Sichuan is cloudy all the year round and foggy in winter because the water vapor on the mountains around the basin covers the basin to form clouds. It takes a cooling time for water vapor to turn into clouds, which also explains why it will be colder after sunny days.

Knowing the above principle, let's talk about what it feels like to be cold and hot.

The cold air just passed some time ago, so the temperature has risen a lot. In addition, the clouds in the sky disperse because of the rising temperature, so the ground temperature rises. At night, because there is no cloud, the temperature drops rapidly, which not only reduces the temperature of the next day, but also reduces the temperature of the mountains around the basin, so the water vapor on the mountains runs to the basin again. Cooling and clouds made the weather cold the next day. Although it's a little cold and cloudy, the sun hasn't changed, and it will heat up slowly during the day. The sun will become much thinner the next day because of the clouds. If you pay attention, you will see the hazy moon and the clouds keep warm, so the temperature will not drop too much the next day. The thinning of the clouds made the clouds clear as soon as the sun came out the next day, so it was sunny again the next day. This cycle is the weather change during this period. If this kind of weather changes, it needs an external cold air or warm current to break it, or when the wind begins to change the overall flow trend of clouds, otherwise it will always be cold and hot.

I usually prefer to watch the weather change, especially when I come out to look for the moon at night. Besides, I never believe in weather forecast, so I often speculate on the Internet based on health cloud pictures, radar reflection pictures and water vapor pictures.

If you are interested in your own research, I can recommend you a website, which is very professional. As long as you know some meteorological knowledge, you can see very professional data. Satellite cloud pictures are all true responses to the weather. As long as you understand them, they should be much better than the weather forecast.
