Why does the weather in Gansu change so fast?

Many of these areas have experienced the feeling of winter overnight, especially after the Mid-Autumn Festival or National Day. After every big festival, they feel that the temperature has changed a lot. The same is true in Gansu, which experienced a crisp autumn overnight, including Henan now. During the National Day, the temperature was as high as 37 degrees, and it returned to 15 degrees overnight at the end. This cooling speed is simply faster than talking.

1. Why is the weather in Gansu changing so fast? In fact, the cooling and precipitation in Gansu has a profound relationship with the cold air in the north going south and the warm and humid air in the south going north. In addition, it is also affected by the cold weather system in winter, so it will lead to changeable weather. In recent days, the temperature has dropped by 5~7 degrees in most places, and even by 7~9 degrees in some places. Not only that, the floating dust in Lanzhou city has risen again, and it is difficult to see the tall buildings in the distance. In addition, the cleaning of floating dust by rivers has also ushered in cooling.

Second, get dressed quickly. Obviously, the first day was still over 30 degrees, with short sleeves and shorts. As a result, autumn clothes and trousers and even coats in colder places have to be put on the day after the night. This temperature changes quickly. When it was very hot, I was still wondering if it was an autumn tiger. When it really cooled down, I found it a little warmer and better. However, the power of nature is indeed relatively large, and this span may be a bit unacceptable for normal people.

Third, keep warm. Because the temperature changes rapidly this time, you must do a good job of keeping warm, and don't let yourself catch a cold or catch cold because of this temporary temperature difference. Therefore, it is necessary to adjust the temperature at any time to avoid some overheating and supercooling situations and make yourself sick. In addition, we should add clothes in time, because cold and hot weather is the most likely to induce colds, especially for the weak elderly and children. In addition, proper sex life is also needed, which is also very important in such weather, otherwise it will aggravate the symptoms of respiratory diseases. Be sure to bask in the sun when you go out.
