In the next three days, the land in the northern bureau will cool down by 10 to 15 ° C.

Recently, my country ’s cold air activities are frequent. Yesterday (September 20), there were many cool cooling in the north, and frost also appeared in parts of the central and eastern parts of Inner Mongolia, northeast region and other areas. It is expected that in the next three days, a new cold air will affect the northern region of my country. In the middle and lower reaches of the Yangtze River, there will be strong wind cooling weather from north to south in the north to south. There will be strong rainfall in the northeast region. In addition, the autumn rain is continuous. It is expected that the Southwest region will still rain in the southwest of September, and the temperature will remain in the downturn. The maximum temperature in Chengdu, Chongqing and other places will drop to about 20-22 ° C.

Cold air will affect most of the north, and the local area cooling is 10-15 ℃

The Central Meteorological Observatory predicts that from the 21st to 23rd, in most areas north of the middle and lower reaches of the Yangtze River, level 4-6 northern winds will appear from north to south. The average daily or minimum temperature in some areas of Huanghuai and other places will drop by 4 to 8 ° C, and the local area will cool by about 10 ° C; the maximum temperature in the central and eastern part of Inner Mongolia drops by 10-15 ° C.

Affected by the cooling down, the temperature in the central and eastern parts of Inner Mongolia, Northeast, North China and other places will be reduced to a minimum, and the minimum temperature of 10 ° C will be located in the southern coastal areas of southern Liaoning, eastern Hebei, central and western Shanxi, southern Shanxi, and south of Shanxi. Southern Shaanxi and other places.

There are strong rainfall in the Northeast region, please strengthen the management of crops field

It is expected that from the 22nd to 23rd, there will be middle to heavy rain in the eastern and northeast of Inner Mongolia and heavy rain; the cumulative rainfall in the south of Heilongjiang, most of Jilin, and northern Liaoning will be 30-50 mm, and the local area is 60-90 mm.

Meteorological experts remind that at present, most rice, corn, soybean and other crops in the northeast are in the late stage of maturity. This cooling process only appears in the northeast of Inner Mongolia and northern Heilongjiang. Most of them are mainly light frost and short duration. Autumn grain crop output has a small impact. However, due to the early typhoon "Plum Blossom", a strong precipitation occurred in the central and eastern parts of the northeast. Some farmland soil in eastern Heilongjiang, eastern Jilin, and central Liaoning was humid. The crop is down, which has a certain adverse effect on the harvest of the later mechanical harvest.

Therefore, it is necessary to pay close attention to the weather changes around the northeast. In the area of ​​more than there are more regions of precipitation, it is necessary to discharge dampness and scattered crops in time; at the same time, do a good job of scheduling agricultural machinery. The soil wet area should be harvested in a timely manner after the fall.

In late September, Sichuan, Chongqing, Yun Gui Shaanxi and other places still rain

It is expected that in late September, the southeast of Tibet, Sichuan, Chongqing, northern Yunnan, northern Guizhou, and south of Shaanxi will still rain. The cumulative rainfall is 4 to 70 % more than the same period of the same year, and the local part is more than 1 times. Among them, from the 21st to 25th, Sichuan, Chongqing, Yunnan, Guizhou and other places will have small rain. There will be decentralized heavy rain or heavy rain. ; From the 26th to 28th, there will be a small process of the rain in the east of the southwestern region and the eastern part of the northwest region, and the local area will be as large as heavy rain.

Geological disaster risks occur in some areas in the southwest, please strengthen prevention

Since August 24, there have been rainy weather in the southwest. There are 15-20 days in the rainy days in most areas. The rainfall in eastern Sichuan, southern Yunnan, southern Shaanxi and other places is 5 % to 1 times more than the same period of the year. There are 2-5 % more northern Sichuan Plateau.

It is expected that the rainfall in the southwest will continue in the next ten days. The risk of disasters such as landslides, collapses, and floods will occur. Among them, from 21st to 25th, southeast of Tibet, northeast of Sichuan and south, southwestern Chongqing, northern Yunnan, northern Yunnan, and northern Yunnan, and northern Yunnan,, northern Yunnan, and northern Yunnan,, northern Yunnan, and northern Yunnan,, northern Yunnan,, northern Yunnan,, northern Yunnan,, northern Yunnan,, northern Yunnan,, northern Yunnan,, northern Yunnan,, northern Yunnan,, northern Yunnan,, northern Yunnan,, northern Yunnan,,, northern Yunnan,,,,, Geological disasters in northern Guizhou, southern Shaanxi and other places are high; in eastern and southern Sichuan, southern and southern Chongqing, northern Yunnan, northern Yunnan, and northern Guizhou have a certain weather risk of flood disasters.

Please strengthen prevention and pay attention to the early warning information released by the local area. Do not go to the hidden danger point of the disaster; the adverse effects of rainfall along the Sichuan -Tibet Railway need to pay attention to the construction and material transportation. The adverse effects.
