Cold air transportation, cooling in the southern region, which areas are affected?

After cold air transportation, Sichuan, Chongqing and other places were obviously affected. With the spread of cold air, the northern part of the south of the Yangtze River and the areas along the Yangtze River will also be affected, and the temperature drop will be obvious.

This year, the weather is a bit abnormal. After entering 5438+ 10 in June, the temperature in the south is still high, especially in Sichuan basin, which is still above 30 degrees. However, as the cold air in the north moves southward, many areas in the south will be affected. According to the latest satellite cloud picture, this cold air will enter many areas in the west of Sichuan Basin through the gap in the north of Sichuan Basin, and then affect the whole Sichuan Basin and its surrounding areas.

First, Sichuan and Chongqing have obvious influence.

After cold air transportation, southern Sichuan, Chongqing and other places will be greatly affected, and the temperature will drop sharply. After the arrival of this cold air, it will directly enter the northwest of the Sichuan Basin from the Sichuan Basin to the gap, bringing cold air with it and autumn rain. When cold air covers the whole Sichuan Basin, the local temperature will drop by more than 10 degrees, and cool weather will appear in autumn. After the cold air enters Sichuan Basin, it will continue to spread eastward. By then, the temperature in Chongqing will also be significantly affected, and there will be a temperature drop of more than 10 degrees. Although the cooling rate is slightly lower than that in Sichuan, it will also make the local area much cooler.

Second, the north of the Yangtze River and the areas along the Yangtze River have obvious influence.

After the cold air is transported, the impact on the north of the Yangtze River and most areas along the Yangtze River is extremely obvious. However, their cooling is relatively late, and the cold air will not cool down until it reaches Chongqing. Cold air arrives in Hunan late, and there will be high temperature and other cold air for several days. After arriving in Hunan, the cooling rate will not be particularly large, but the local maximum temperature will drop below 30 degrees, but those areas will maintain a state of continuous high temperature without the arrival of cold air.

Third, pay attention to keep warm when cold air comes.

After this cold air is delivered, Chongqing, Sichuan and most areas along the Yangtze River will be obviously affected. The temperature drop in some areas exceeds 15 degrees. At this time, we must pay attention to keep warm, because before the arrival of cold air, these areas in the south are in a state of continuous high temperature, and the lowest temperature is above 30 degrees. The temperature in some areas is still above 35 degrees. Under the influence of cold air, it is necessary to add clothes to pay attention to cold protection, otherwise it is easy to catch a cold.
