Why is Panzhihua more than 20 degrees during the day and only 6 degrees at night?

Why is Panzhihua more than 20 degrees during the day and only 6 degrees at night? Thank you for your question. I don't quite understand. Let's talk by feeling!

First, my family lives in the rural areas in the remote mountainous areas of Panzhihua. I was originally from the northern Central Plains. After living in Panzhihua, I feel that the climate between mountainous areas and plains is very different!

Second, I think it should be the climate characteristics of Panzhihua high-altitude deep mountain canyon! The altitude of Panzhihua area is about 1000 meters at the lowest point of Jinsha River, while the slopes on both sides of Jinsha River are above 1000 meters, and the mountain ridge where my home is located is as high as 1300 meters. Because winter in Panzhihua is a dry season, it is sunny almost every day, and the cold air is blocked by mountains and valleys. The sun shines during the day and the temperature rises rapidly. At night, after the sun goes down, there is less water vapor in the atmosphere, the air dissipates quickly, and the air heat capacity is poor, just like the battery of an old mobile phone. Just charge it and it will be full. Without playing with your mobile phone a few times, the battery will be dead. This is the characteristic of alpine climate. The temperature difference between day and night is large, and the temperature difference in Panzhihua area can reach more than 20! Therefore, it is the habit of local farmers to keep warm around the fire when the sun goes down in winter! The ethnic minorities in the mountains are also very happy to cook camellia while heating, and they have distinct alpine customs and habits! Welcome to Panzhihua for sightseeing! I'm done, thank you!

Altitude: 1000 meters, resulting in thin air over the plateau and less water vapor and dust content. During the day, when the solar radiation reaches the plateau, it not only passes through the atmosphere (compared with the plain area), but also is weakened less by the thin gas.

Therefore, the ground gets more solar radiation and the temperature is relatively high (but because of the thin air over the plateau, the ability to absorb ground radiation is weak, and the temperature is still low compared with the plain area at the same latitude); At night, due to the weak heat preservation effect of the thin gas on the ground, the temperature drops rapidly.

Generally speaking, the temperature difference between day and night is larger in inland areas and smaller in coastal areas, because the specific heat capacity of water is greater than that of soil. The observation and research on urban heat island show that urban heat island is strong at night and weak during the day. In sunny and calm weather conditions, the heat island effect is very strong.

Presumably, many Panzhihua people are like this-"It's cold and silly to get up early in the morning and open the window."

When you go out in the morning and evening

I found that everyone's equipment suddenly upgraded from short sleeves to down jackets.

This wave of cooling in Panzhihua is simply too steep!

Then when you check the weather forecast,

You will find that in the recent or even future 15 days.

The temperature difference in Panzhihua is getting bigger and bigger!

The whole temperature difference 14!

Next, the daily life of Panzhihua people may be

Morning: Get dressed.

Noon: take off your clothes

Evening: Add clothes.
