Is there cold air at the autumn equinox of 202 1?

The autumnal equinox solar term is a solar term in autumn every year, and also a special solar term. At this time, most areas have entered autumn and summer is over. The weather will gradually turn cold, the temperature will drop, and there may be cold air in the north of China.

Is there cold air at the autumn equinox of 202 1? There may be cold air, especially in northern China.

The autumnal equinox solar terms are affected by strong cold air. Most of the central and eastern parts of China have different degrees of cooling from north to south. In this round of cooling, many places in North China welcome autumn. The change of the lowest temperature in the Middle East is particularly obvious, and the coolness in the north of the Yangtze River is getting bigger and bigger at night and in the morning and evening.

At the autumnal equinox, most parts of China enter a cool autumn. The cold air from the south meets the warm and humid air that gradually decays, which leads to the precipitation and temperature dropping again and again. As people often say, it's time for "one rain and one cold", but the daily rainfall after the autumnal equinox will not be very heavy.

Affected by the eastward movement of the plateau trough, most of the Qinghai-Tibet Plateau, southeastern part of northwest China, Sichuan, Chongqing, northwestern Guizhou, central and northern Yunnan and other places have small to moderate rain, and some areas have heavy rain or rainstorm 2 1 ~ 23. All the above areas are accompanied by strong convective weather such as short-term heavy precipitation.

Will the autumn equinox cold air go south? There may be cold air heading south.

After the Millennium solar term, the autumnal equinox came, cold air moved south in batches, and the weather turned cold in most parts of South China. This time is very comfortable for human body, but it is fatal for cultured animals, because after the weather turns cold, the water temperature drops, and all kinds of harmful bacteria and parasites can recuperate in large quantities, which is very harmful to cultured aquatic products.

At present, the "autumnal equinox" solar term has passed, and cold air continues to accumulate in the hinterland of northern Eurasia. When there is a suitable weather system, cold air will move eastward and southward, affecting our country. As far as this cold air activity is concerned, there is a deep trough in northern Central Asia. Under the guidance of the trough, cold air enters Xinjiang southward and affects the central and eastern regions of China from west to east. The characteristics of this cold air activity are "moving eastward quickly and moving southward slowly". At present, there is an east-west zonal circulation in the upper atmosphere of China, and cold air cannot spread rapidly from north to south. Therefore, cold air moves eastward, expands rapidly in the northern region, and shows the characteristics of slow infiltration when it goes south. Therefore, the cold and warm air in the south of the Huaihe River in Qinling Mountains is obviously confronted, with frequent rainfall and long rainfall time, while the rainfall time in the north is short and the rainfall is small.
