The first cold wave of this year


At present, a new cold air is brewing in Siberia to Mongolia. It is expected that from tomorrow (13th) to 16th, the strong cold air will “head south” and affect 29 provinces and cities in China. At that time, the strong wind, cooling and rain and snow weather will come together, which is likely to sound the first cold wave warning this year! This cold wave process has three characteristics of rapid cooling, wide range and strong intensity. There is Blizzard in the northern region, with a cooling range of more than 14 ℃.
This year’s first cold wave warning is about to ring in Beijing, Tianjin and Hebei region, which may face the strongest snowfall this winter
In recent days, I believe that many netizens feel that most of China’s regions are not really warm. The temperature of major cities in the Middle East has repeatedly reached new highs. However, this is a “blind way” caused by the temperature. It is expected that starting tomorrow, cold air will break out in the south, and rain, snow, strong wind and temperature drop will affect most of China from the north to the south.
First come to see the rain and snow. From today’s night to tomorrow, the snowfall in the Middle East of Inner Mongolia and Jilin Province of Heilongjiang Province is the first to increase. But the snow is still on the 14th-15th. There may be large-scale snowfall or rain to snow in North China and Huanghuai river. The area of Beijing, Tianjin and Hebei may reach the level of Blizzard, or it will be the strongest snowfall this winter (2019-2020 winter). Beijing is expected to receive the seventh snowfall in this winter. On the 15th, the snowfall center moved eastward and southward, and gradually moved southward. Liaoning, Shandong and other places may also welcome it It’s a blizzard, a local blizzard.
In terms of temperature, the script of “roller coaster” was staged again. On December 14, many areas in the Middle East were still warm as early spring, and then the strong cold air with strong wind brought rain and snow all the way south. On March 13-17, the temperature also “dived” all the way, from northeast to South China, with a general cooling range of 10 ℃. Inner Mongolia, Jilin, Heilongjiang, Shandong may even reach 15 ℃, from warm as spring to Shivering, maybe only overnight.
Cool down! Wide range! Strong strength! “All-round” cold air or disturbing spring transportation
According to Hu Xiao, chief meteorological analyst of China Weather Network, this cold wave process has three characteristics: fierce cooling, wide range and strong intensity. In the early stage, China’s central and eastern regions heated up rapidly, just like a roller coaster, which made the subsequent temperature drop very prominent. It is expected that the northeast, North China, the east of Northwest China, Huanghuai, Jiangnan, etc As far as South China and other places are concerned, they can’t escape the “attack” of the cold wave process. The temperature drop will generally exceed 10 ℃, and the accumulated temperature drop in the north will even reach 20 ℃.
It is worth mentioning that in Northeast China, Inner Mongolia and other places, this time not only the maximum temperature drops obviously, but also the minimum temperature drop will be more prominent. For example, the minimum temperature in Changchun on the 13th will be above or below 0 ℃, and on the 17th, it is expected that the minimum temperature will drop to – 19 ℃, and the cumulative cooling range will be close to 20 ℃!
In addition to cooling, this cold air will bring a very strong snowfall! On the 14th-15th, there will be strong snowfall in North China and Huanghuai, and on the 14th, there will also be heavy snow in Beijing, Tianjin and Hebei. It is worth noting that many places in the Middle East may also have rain and snow changes, and the snow line may be pushed southward to the central area of the south of the Yangtze River. Changsha, Nanchang, Shanghai and other places may have short-term snow around the 16th. In Lingnan area, the cold wave will fight against the main body of the warm and humid air flow, and thunder may be heard when rain falls in Guangdong, Guangxi, Fujian, Hainan, Jiangxi and southern Hunan.
To sum up, this year’s first cold wave process will be an all-around player, with a lot of rain, snow, wind and cooling. It is worth mentioning that the temperature fluctuates greatly in this cold wave process, especially in the south where there is no heating. With the rainfall cooling, the body will feel colder and colder. The public should pay attention to adding clothes to keep warm and prevent colds. On the diet, they should drink more cold driving drinks such as jujube tea, ginger water and longan tea.
In addition, the spring return tide is continuing. This rain and snow, cooling weather process or adverse impact on railway and road travel, especially the public driving back, should pay attention to the forecast, early warning and road closure information issued by the meteorological department and transportation department in advance, arrange travel time reasonably, and pay attention to the visibility reduction and road wet and slippery knot caused by rain and snow Adverse effects of ice and other conditions.
