Climatic characteristics of cold dew

The climatic characteristics of cold dew are as follows:

The temperature drops faster and drier. The rapid drop in temperature is a feature of the cold dew solar terms, and the weather becomes drier. At this time, the geese fly south and the chrysanthemums turn yellow. Compared with the "white dew" a month ago, the temperature is lower, the dew is more, and it is chilly. 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℃, while 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. 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.

Rainfall is scarce and thunderstorms almost disappear. With the arrival of cold dew, most parts of China will turn cold, and the northeast and northwest regions have entered or will soon enter winter, with less rain. In addition to the perennial snow on the Qinghai-Tibet Plateau, it has generally begun to snow in the northeast and northern Xinjiang.

Cold dew solar terms weather conditions

The Central Meteorological Observatory predicts that there will be 5-7 winds in northern Xinjiang and western Inner Mongolia on 3-4 days, and the temperature will drop by 8- 10℃, and the minimum temperature can drop to-1-5℃; On May 7th, there were 4-6 northerly winds in the east of northwest China, north-central North China and northeast China, and the temperature dropped by 4-8℃. The lowest temperature in the east and northeast of northwest China is 1-4℃.

North China 6-10℃; There is sleet or snow in northern Xinjiang, northeastern Inner Mongolia and northwestern Heilongjiang. That is, there will be obvious cooling in northern China in the early stage of cold dew. In addition, it is predicted that there will be 10- 13 gale in bashi channel, east of Taiwan Province, Taiwan Province Strait, East China Sea and eastern Yellow Sea on April 7th.

The wind power in some sea areas can reach14-17; On May 6th, there was heavy rain in Fujian, Zhejiang, Shanghai, southern Jiangsu and other coastal areas, and there was heavy rain in some areas, and there was heavy rain in Taiwan Province Province. Coastal tourist traffic needs to guard against strong winds and heavy rains.
