Meanwhile, the temperature of the whole province also dropped significantly.
Yesterday, strong rainfall developed again in the southeast of Northwest China and the east of Southwest China. The monitoring shows that there are heavy rain or rainstorm in Northeast Sichuan, Southeast Shaanxi, West Henan, West and northeast Hubei, North Zhejiang and West Shandong, West and South Yunnan, and heavy rain in Dazhou and Hanzhong of Sichuan.
According to chinaweather.com, the cold air is still strong today, and the south central and northeast areas of North China will usher in the second consecutive day of cooling. The temperature in the central and eastern part of the North was high before. In this cooling process, it will turn to be lower than that in the same period of the whole year. The long delayed autumn process in the North China and the Huanghuai area will be reopened and quickly pushed forward to the Huaihe River.
At the same time, it will get colder sooner or later, especially the lowest temperature in Northeast China will generally only be about 5 ℃, pay attention to keeping warm. The first frost will appear in some areas of Heilongjiang and Jilin in the morning, so we should pay attention to prevention.
However, the impact of cold air on the cooling in the southern region is relatively small. Most of Jiangnan will get rid of the hot weather and usher in cool weather successively. However, the cooling in South China is relatively small. There are still large areas of high temperature in Fujian, Guangdong and other places, and there will be high temperature in Fuzhou, Guangzhou and Nanning, provincial capital cities. People in Fujian, Guangdong, Guangxi and other places still need to pay attention to heatstroke prevention.
Zhang Tao, chief forecaster of the Central Meteorological Observatory, said in an interview that this is the strongest cold air in China since the autumn. On the night of the 23rd, cold air came into China from Xinjiang and affected most of the central and eastern regions of China from west to East. After the 28th, the impact of cold air in this round tends to end.
Zhang Tao said that in this cold air process, strong winds in the north are more obvious. Among them, the average temperature in Xinjiang, most of Inner Mongolia, the east of Gansu, the middle and north of North China, and most of Northeast China will drop by 6-10 ℃, and the temperature drop in some areas of Northern Xinjiang, central Inner Mongolia and other places will reach more than 12 ℃, and most of the northern areas are accompanied by 4-6 northerly winds.
"This cold air activity is characterized by & lsquo; fast eastward movement and slow southward movement";. At present, there is a straight East-West zonal circulation in the middle and high altitude in China, which makes the cold air unable to expand rapidly from north to south. Therefore, the cold air moves and expands rapidly in the East in the north, and slowly penetrates in the south. Because of this, the cold and warm air in the south of the Huaihe River in Qinling Mountains is obviously facing each other, the rainfall is more frequent and the rainfall time is longer, while the rainfall time in the north is shorter and the rainfall is smaller. "Zhang Tao said.
According to the forecast of China Weather Network, the cold air will continue to affect most of the central and eastern regions of China from 27th to 28th. The average temperature or the lowest temperature in the central Inner Mongolia, the north of North China, the east of Northeast China, the east of Southwest China, the south of Jianghan, Jiangnan and other places will drop by 4-6 ℃, and the local cooling range can reach over 8 ℃. There are 4-6 northerly winds in most areas of the north.
