In the past few days, the weather on the Asian continent has been relatively calm, only the marine areas have been restless one after another, and two tropical storms have appeared in succession, making the northwest Pacific Ocean and the Northern Indian Ocean active again. By 6 December, the weakened deep, low-pressure Jawad cloud system had completely dissipated and the ocean had temporarily calmed down. On the contrary, the weather on the continent that has been calm for a long time is about to be lively again, especially in the northern region, where a new round of rain and snow is brewing and is about to start, which will be the first round of widespread snowfall in December, which is worth noting.
The official forecast pointed out that this round of snowfall lasts for 4 days, roughly 7-9 days, and the snowfall will affect many provinces and regions in the north, and will gradually move east from west to east. Specifically, from 20:00 on December 6 to 20:00 on December 7, there will be heavy snowfall in central and southern Qinghai, north-central Tibet, southern Gansu, Ningxia, western and northern Shaanxi, and the western part of Hohhot, Inner Mongolia, with most light snow or sleet, and moderate snow in some areas near Yinchuan in Ningxia, with a maximum precipitation of 4 mm. On December 8, snow moved eastward.
There is a wide range of snowfall in central and eastern Qinghai, southern Gansu, north-central Shaanxi, Ningxia, central Inner Mongolia, northern Shanxi and other provinces and regions, most of which is light snow, moderate snow in western Shaanxi and parts of central and western Inner Mongolia, and there is heavy snow locally, with a maximum snowfall of 6-8 mm. On December 9, the snow in the north continued to move eastward, mainly in eastern and northeastern Inner Mongolia, northern Beijing-Tianjin-Hebei, and western Heilongjiang. At the same time, snowfall in northern Xinjiang, that is, north of the Tianshan Mountains, has expanded across the board, with 8-9 mm of heavy snow in the Ili River Valley and the Alta mountains.
By the 10th, the current round of snowfall in the north was basically over, and in terms of the impact of cooling, it was not large. In fact, although it has just entered December, which is the first month of winter in the true sense, the cold air is not active, and even the intensity is not large. The official mid-term forecast points out that in the next 10 days, the cold air will be weak, and the temperature in most parts of the country will be higher than the same period of the year, especially in parts of northern China, northeast China, eastern Huanghuai and other places, which may be about 4 to 6 ° C higher. As a result, it feels like the whole winter is not cold at the beginning, but warmer.
So before I thought that this year's twin peaks La Niña came, the cold air in winter is more frequent, the probability of cold winter is large, and now it seems different, will the situation change greatly? In fact, La Niña is true, and the possibility of cold air in winter is also played, mainly referring to December to February of the following year, the more cold air there is in the later stage, the more severe. For now, although the next 10 days are warm, and even this month's temperature is high, it does not mean that this winter is not cold. And whether it is a cold and warm winter, look at the specific data from December to February, then everything is based on the data.
