What's the weather temperature on October 1st?

The National Day has passed the autumnal equinox, and the Yangtze River basin and the vast areas in northern China have entered autumn one after another, and the daily average temperature has dropped below 22℃. Before and after the National Day, the sun almost shines directly at the equator, and the length of day and night in most parts of the world is similar. At this time, the weather temperature in the southern region usually drops below 22℃ and enters the cool autumn. The cold air heading south meets the disappearing warm and humid air, which produces rainfall and the temperature drops again. So, please pay attention to the autumn rain.

The temperature in most parts of South China continues to drop. The daily average temperature in South China is below 20℃. Even in the areas along the Yangtze River, it is difficult for mercury column to rise above 30℃, while the minimum temperature can drop below 10℃ ... Except for some valleys and lowlands in the northwest plateau, the average climate temperature (5 days) is usually below 10℃. According to the climate standard, it is winter now.

2. The weather in the north

In the northeast, it is not surprising to see frost in the morning. In the northeast, the National Day is obviously getting cold. During the National Day, we should pay attention to keeping warm and don't catch a cold when going out to play.

In the northern part of the northwest plateau, the minimum temperature dropped below 0℃ before and after the National Day, and people saw spectacular snow scenes, flying in the sky and the earth covered in silver.

The cold air in the north began to have a certain impact. In most areas, the rainy season has just ended, with a cool breeze blowing gently, blue sky and white clouds, the sun shining high, strong autumn breath, sweet-scented osmanthus fragrance, crab fat and chrysanthemum yellow, and the autumnal equinox is a beautiful and pleasant season. It is also an important solar term in agricultural production. After the autumnal equinox, the position of direct sunlight moved to the southern hemisphere. The northern hemisphere receives less and less solar radiation, while the ground emits more and more heat, and the temperature drops significantly faster.

The weather characteristics of 10.

The temperature drops faster and drier.

It is common for the temperature to drop by 8℃ and 10℃ after the autumn rain brought by a strong cold air. However, most stormy weather does not last long (except West China). Controlled by cold and high pressure, it is warm during the day, cool at night and crisp in autumn during the day. The weather has also become drier.

The average temperature distribution varies greatly.

From June 5th to 10, the regional difference of the average temperature distribution in China is obvious. The average temperature in most parts of South China is above 22℃, and it is even higher in Hainan, which is above 25℃, and it has not yet come out of summer. Jianghuai and Jiangnan are generally between 15℃ and 20℃, and the southeast, North China and Huanghuai are between 8- 16℃. At this time, the average temperature in parts of the northwest and north-central northeast has reached below 8℃. The average temperature in some plateau areas of Qinghai Province is even lower than 0℃.

Cold air frequently goes south.

According to climatology, after the cold dew, the cold air in the north has a certain influence, and most parts of China are controlled by cold high pressure, and the rainy season is over. The weather is usually warm during the day and cool at night, with clear skies in Wan Li and a scene of late autumn. In normal years, at this time, the isotherm of 10℃ has moved southward to the Qinling Mountains and Huaihe River, and generally falls below 0℃ to the north of the Great Wall. The first frost can be seen in most years in Beijing, the capital. After entering the "cold dew", the invasion frequency and intensity of cold air in the north will increase, and the rapid temperature drop is a major feature of the "cold dew" solar term. It is common for the temperature to drop by 8℃ to 10℃ after the autumn rain brought by a strong cold air.
