Original title: strong cold air affects many places in the north, and the temperature will drop like a cliff
From October 3 to October 2, strong cold air will affect the area north of the Yangtze River from north to south. Affected by this, from the night of the 2nd to the 5th, there was a wide range of gale cooling and rainfall in the north of the Yangtze River, and the temperature in some areas could reach more than 12 ℃. At the same time, there will be light to moderate rain in most areas and heavy rain in local areas.
Strong cold air affects the local cooling in the north, which can reach more than 12 ℃
Since autumn, there has been no obvious cooling weather in most parts of the north. But recently, a strong cold air is affecting most parts of the north from west to East. Affected by this, from the night of October 2 to October 5, large-scale gale cooling and rainfall will continue to occur in the north of the Yangtze River, and some areas will experience 'cliff cooling'.
From the cooling situation, it is expected that the air temperature in most of Inner Mongolia, most of Northeast China, northern Shanxi, Hebei, Beijing and Tianjin will drop by 6 ~ 10 ℃ from the early morning of the 3rd to 20:00 on the 4th. Among them, the temperature drop in some areas in southern Heilongjiang, central and Western Jilin, western Liaoning, central and Southeast Inner Mongolia can reach more than 12 ℃.
In terms of rainfall, from the night of the 2nd, it was cloudy and rainy in the east of Southwest China and the west of Huang Huai River. Among them, there are heavy rains and local rainstorms in some areas such as the east of Sichuan Basin, the south of Shaanxi and the west of Henan.
This cold air also brings windy weather to many places. It is understood that north of the Yangtze River, such as Hexi in Gansu, the central and western parts of Inner Mongolia, the central and western parts of Northeast China, the eastern and southern parts of Hebei will have a northerly wind of level 4 ~ 6, and the gust can reach level 7 ~ 8. At 18:00 on October 2, the Central Meteorological Observatory continued to release the forecast of strong wind and cooling.
The impact of typhoon 'Mina' gradually weakened
This year's No. 18 typhoon 'Mina' landed in Putuo, Zhoushan, Zhejiang Province (Level 11, strong tropical storm level, 30m / s) around 20:30 on October 1.
Affected by typhoon 'Mina', since September 30, the cumulative rainfall in eastern Zhejiang, Shanghai, Nantong, Jiangsu and other places has exceeded 100 mm, and the local rainfall in Zhoushan has reached 400 ~ 443 mm. At the same time, 8-10 gusts occurred along the coast of eastern Fujian, eastern Zhejiang, Shanghai and Southeast Jiangsu, and 12-15 gusts occurred locally along the coast of eastern Zhejiang.
Under the influence of typhoon 'Mina', from 8:00 on October 2 to 8:00 on October 3, there were strong winds of force 6 ~ 7 in the north of the East China Sea, Hangzhou Bay, the coast of Northern Zhejiang, the coast of Shanghai and the coast of central and southern Jiangsu. Among them, the wind force in some sea areas or areas along the northern coast of Zhejiang, the northern part of the East China Sea and the southeast part of the Yellow Sea is 8 ~ 9 and the gust is 10 ~ 11.
According to the Central Meteorological Observatory, typhoon 'Mina' weakened from strong tropical storm level to tropical storm level on the afternoon of the 2nd, and landed along the coast of quanluonan Road, South Korea at about 20:10 on the 2nd. Affected by the typhoon, from 20:00 on the 2nd to 20:00 on the 3rd, there will be strong winds of force 6-7 in the north of the East China Sea, the Middle East and south of the Yellow Sea. Among them, there will be winds of force 8-9 and gusts of force 10-11 in some sea areas or regions in the northeast of the East China Sea and the southeast of the Yellow Sea.
Windy and rainy weather lasts for the next three days. Pay attention to adding clothes to avoid rain
According to the Central Meteorological Observatory, the gale cooling and rainfall in the north of the Yangtze River will continue from March 3 to 5. People in relevant areas need to wear clothes to avoid rain.
According to the forecast, from 20:00 on the 3rd to 20:00 on the 4th, some areas in northern Jilin, Eastern Heilongjiang and Eastern southwest will have moderate to heavy rain. Among them, there are rainstorms (50 ~ 65mm) in the East and south of Sichuan Basin, Northwest Guizhou and Northeast Yunnan.
At the same time, some areas in western Inner Mongolia, Hexi, Gansu and Northern Huang Huai will also have winds of grade 4 ~ 6 and above. The Bohai Sea and the Yellow Sea will have northeasterly winds of magnitude 7 ~ 8 and gust of magnitude 9. Pedestrians should avoid dangerous areas such as billboards and construction sites.
From 20:00 on the 4th to 20:00 on the 5th, the gale weather will not weaken. For example, there are grade 4 ~ 6 winds in some areas of Western Inner Mongolia, central and southern Liaoning, most of Huang Huai and Jianghan. There will be northerly winds of force 6 ~ 8 and gust force 9 in most of the Bohai Sea and Yellow Sea.
In addition, the rainfall in the north of the Yangtze River also needs attention. For example, moderate to heavy rain will continue in some areas, such as the east of Northwest China, the south of Shanxi, the west of Huang Huai, the East and south of Southwest China. However, there are rainstorms and local heavy rainstorms (100 ~ 120 mm) in some areas such as southern Shaanxi and Eastern Sichuan Basin. The Central Meteorological Observatory reminded people in the eastern part of Southwest China and southern Shaanxi to be vigilant against secondary disasters that may be caused by continuous rainfall.
