On the afternoon of January 23, from the Fengyun-4 high-definition visible light satellite cloud map, there is a large range of clouds in the central and eastern regions east of the Qinghai-Tibet Plateau on the mainland today, and even some of the clouds have extended to the Korean Peninsula and the Japanese archipelago in East Asia.
Judging from the monitoring data of the Central Meteorological Observatory, from January 22 to January 23, there was light snow or sleet in eastern Gansu, central Shaanxi, southwestern Shanxi, Henan, Shandong, northwestern hubei and southern Hubei, and even moderate to heavy snow in eastern Shaanxi, western Henan and parts of central Shandong. In most of the southern part of the mainland, it is still mainly precipitation, and heavy rain has occurred in northern Zhejiang, northern Jiangxi, south-central Hunan, and parts of northeastern Guangxi, and even heavy rain has even occurred in some parts of Jiangnan.
Whether the large-scale snowfall in the north continues, or the moderate to heavy rain in many places in the south or even localized heavy rain, it shows that the warm and humid water vapor in the central and eastern parts of the mainland is still sufficient, and even the excessively strong warm and humid water vapor makes the coastal parts of the south china of the mainland extremely wet, and there is a similar state of "returning to the south". From the forecast of the Central Meteorological Observatory, it is also pointed out that in the next ten days (January 23 to February 1), the rainy and snowy weather in eastern Gansu, Shaanxi, Henan and most of the southern regions, from the national precipitation forecast map, the eastern part of the Qinghai-Tibet Plateau region of the mainland has drawn a rainy snow belt, and it is believed that the precipitation in many places will be significantly more than the same period of the year.
From the supercomputer's forecast, due to the emergence of the situation of large south trough lock-in, the water vapor of the Bay of Bengal in the Northern Indian Ocean will continue to be transported to the south of the mainland, and the current large-scale rain and snow is only part of the recent sustained large-scale rain and snow in the central and eastern regions, and many southern provinces, the recent rain will continue to fall endlessly - such as Hangzhou, Zhejiang, the forecast shows that from January 23 to January 29 will be soaked in boundless rainy weather, especially next Thursday (January 27), The temperature in the rain will drop further, not only the minimum temperature will be close to 0 degrees, but the maximum temperature may also slide below 5 degrees. This is the infiltration of the northern cold pile in the later stage, so in the later period, many places in the south will not only be rainy, but also the wet and cold body feeling will be significantly strengthened.
Recently, although many places in the south of the mainland have been rainy, some photos taken by some netizens in Zhejiang show that the branches of red plums in many parts of Zhejiang have been dotted with dense flower buds and are about to bloom. At present, Zhejiang and even the whole south will be shrouded in rain, at least for a week, and it will become a real "plum blossom rain".
However, the forecast of the Central Meteorological Observatory also pointed out that with the intensification of the penetration of cold reactors to the south in the later period, in addition to the intensification of wet and cold in many places, the rain and snow dividing line also has a trend of pushing southward. For example, from January 27 to January 28, in addition to snowfall in Henan and other places in the north of the mainland, the snowfall in Hubei Chongqing, Anhui, Hunan, Guizhou and other places will also increase significantly, and the blizzard area will begin to show signs of advancing to the southern region, which means that the snowfall in the south may be further expanded in the later period, and there is a possibility of more snow in some areas.
