The strongest cold air strikes 202 1.

202 1 the strongest cold air hit, and the temperature in most parts of China was lower than normal in the middle and late period. It is worth noting that after this cold air, there will be a weak cold air affecting northern China around 19. The strongest cold air strikes 202 1.

The strongest cold air hit the Central Meteorological Observatory in 2002 1 year1. Affected by strong cold air, it is predicted that there will be strong winds, rain and snow in the central and eastern regions of China from June 14 to June 17. It is predicted that the temperature in most parts of China will be lower than normal in the middle and late days of 10. The specific forecast is as follows:

Gale cooling forecast: 14 ~ 17, the temperature in the eastern part of northwest China, North China, Northeast China, Huanghuai, Jianghuai, Jianghan, Jiangnan and Guizhou will drop by 6 ~ 10℃ successively, and the cooling range in some areas can reach12 ~10. There are 4 ~ 6 northerly winds in most of the above areas, and 7 ~ 9 gusts in eastern Inner Mongolia, northern North China, eastern and southern Northeast China. From June/KOOC-0/6 to June/KOOC-0/7, there are 7 ~ 9 winds in the eastern and southern seas, and the gust wind in the Taiwan Province Strait can reach/KOOC-0/0 ~/KOOC-0/. 17 The minimum temperature line at 0℃ in the morning is located in southern Gansu, northwestern Shaanxi and south-central Shanxi to central Hebei and Beijing.

Rain and snow forecast: from 13 to 16, there will be moderate to heavy rain in southern Shaanxi, Huanghuai, eastern Jianghan, Jianghuai and northeastern Jiangnan, and there will be small to medium snow or sleet in eastern Qinghai, central and eastern Gansu, southern Ningxia, northeastern Inner Mongolia and Heilongjiang, and there will be heavy snow in the local area.

After this cold air, there will be a weak cold air affecting the northern part of China around 19.

Since June 5438+ 10, there have been frequent cold air activities affecting China. It is predicted that before June 24, 65438+ 10, the temperature in most parts of China was obviously lower than that in the same period of normal years, and the temperature in the eastern part of northwest China, southern North China, southern Northeast China, Sichuan Basin, Huanghuai, Jianghan, western Jiangnan and Guizhou was 3 ~ 4℃ lower. After the 25th, the cold air weakened and the temperature rose in stages. The temperature in Xinjiang and Northeast China is slightly higher than normal, while the temperature in most other parts of China is slightly lower.

Meteorologists reminded that after the cold air, the minimum temperature in central and southern Shanxi, northwestern Shaanxi and southern Gansu will drop below 0 C. Please ask the public to add clothes in time and do a good job of rain protection and warmth in the affected areas. In addition, since September, there has been more precipitation in most parts of the north, among which the precipitation in the eastern part of the northwest, North China, Huanghuai and other places is 1 ~ 2 times higher than normal, and the precipitation in Shaanxi, Shanxi, Hebei and Henan is more than 4 times higher. The situation in autumn flood season is severe, and the above areas need to guard against geological disasters, urban and rural waterlogging and farmland waterlogging that may be caused by overlapping rainfall areas.

The strongest cold air strikes 202 1. According to the Central Meteorological Observatory, due to the influence of strong cold air, it is expected that there will be strong winds and rain and snow in the central and eastern regions of China on June10-June 17, and the temperature in most parts of China will be lower than normal in the middle and late years.

In terms of gale cooling, 14 ~ 17, the eastern part of northwest China, North China, Northeast China, Huanghuai, Jianghuai, Jianghan, Jiangnan and Guizhou will be cooled by 6 ~ 10℃ successively, and the cooling range in some areas can reach12 ~10.

At the same time, there are 4 ~ 6 northerly winds in most of the above areas, and 7 ~ 9 gusts in eastern Inner Mongolia, northern North China, eastern and southern Northeast China.

From June/KOOC-0/6 to June/KOOC-0/7, there are 7 ~ 9 winds in the eastern and southern seas, and the gust wind in the Taiwan Province Strait can reach/KOOC-0/0 ~/KOOC-0/.

17 The minimum temperature line at 0℃ in the morning is located in southern Gansu, northwestern Shaanxi and south-central Shanxi to central Hebei and Beijing.

In terms of rain and snow, from 13 to 16, there will be moderate to heavy rain in southern Shaanxi, Huanghuai, eastern Jianghan, Jianghuai and northeastern Jiangnan, and small to medium snow or sleet will appear in eastern Qinghai, central and eastern Gansu, southern Ningxia, northeastern Inner Mongolia and Heilongjiang, with local heavy snow.
