Starting today, the stable weather pattern will gradually move towards "crazy". A new wave of strong cold air is affecting our country, bringing a sharp and short-term cooling, and a strong warming will sweep most of the central and eastern regions, and the temperature will rise again!
However, with the praying mantis catching cicadas and yellow finches, the first cold wave of the Year of the Dragon is ready to start and will begin to affect our country on the 17th. Starting after the holiday, the high temperature pattern in most parts of our country will be completely reversed, and at the same time, the new range of rain, snow and freezing weather will also appear again!
On the same day, the temperature trend in the north and south was "polarized".
From the live map of temperature change at 15 o'clock today, there is a huge difference in temperature between the north and the south. Most of the northern parts affected by the new strong cold air have cooled down sharply, especially in the south of Shaanxi, southwest Liaoning, northern Hebei, and some parts of northern Shandong, which have dropped by more than 16 and more than 18 locally.
The south has not yet been affected by the cold air, and the temperature continues to rise! As of 16 o'clock today, a total of 8 provincial capital-level cities have hit a new high in the highest temperature this year: Hefei 24, Nanjing 241. Shanghai 229, Hangzhou 243, Changsha 265, Nanchang 252, Kunming 206, Fuzhou 268, of which Nanjing is over 20 for the first time this year, and Changsha is over 25 for the first time this year.
The temperature "waveform" is shifted, and the switch between cold and warm is frequently staged.
Today's comparison of the temperature between the north and the south is just a rehearsal of the temperature trend in most parts of China in the next few days of the Spring Festival holiday, and the switch between cold and warm will be frequently staged!
From tonight to tomorrow, under the influence of cold air and rain, the temperature in the middle and lower reaches of the Yangtze River will generally drop by 4 8, and some areas will drop by 10 12. This cold air will briefly bring the currently high temperatures back to around normal levels.
Pay attention to the temperature in Jianghuai and Jiangnan, which will drop sharply! From the three-hour temperature forecasts in Changsha, Wuhan, Nanchang, and Nanjing, we can see that there will be more than 20s tonight, and it will only be about 10 tomorrow afternoon, or even lower!
Since the 16th, the warm air has quickly counterattacked, and the cumulative increase in the maximum temperature in the middle and lower reaches of the Yangtze River can reach 8 10, and more than 12 in some areas! Around the 19th, the highest temperature in many places in Jiangnan and South China can reach about 30, which is close to or breaking the highest record in the same period in history!
The maximum temperature in Fuzhou on the 19th and 20th has been predicted to be 30, which shows the strength of the recovery!
Coming after the Cold Wave Festival! Then meet the test of large-scale rain, snow and ice.
Although the cold air also brought rain and snow this time, the process was short, and the impact on the return trip during the Spring Festival holiday would not be too great. The real test comes from the first cold wave of the Year of the Dragon that began to affect our country on the 17th!
At the end of the holiday, a strong cold wave will appear from the northern part of Xinjiang and affect most of the central and eastern regions from west to east!
On the 17th, the cold wave began to affect my country, and the northern part of Xinjiang will be the first to have a sharp drop of more than 18, while the temperature in the central and eastern regions is still rising!
This cold wave will completely reverse the warming pattern, especially in the middle and lower reaches of the Yangtze River, where the warmth is most prominent in the early stage, the cooling will also be the most drastic, and the cumulative drop in local maximum temperature can even exceed 20 °C. Starting in late February, the temperature in the south will turn significantly lower, and the highest temperature line 0 may reach the Yangtze River!
Specifically, according to the medium-term forecast of the ** Meteorological Observatory, from the 17th to the 21st, there will be a cold wave from west to east and from north to south to affect most parts of China, and the temperature will drop by 6-10, 12-16 in some areas, and more than 18 locally;
Land winds of 4-7 with gusts of 7-9, winds of 6-8 with gusts of 9-10 in the eastern sea; Western Inner Mongolia, western Gansu and other places have floating dust or blowing sand;
From the 18th to the 22nd, rain will turn to sleet or snow in Northeast China, the eastern part of Northwest China, North China, Huanghuai, Jianghuai, Jianghan and other places, Heilongjiang, Shaanxi, Henan, Shandong, northwest Hubei and other places will have heavy to heavy snow, light to moderate rain in the south of the middle and lower reaches of the Yangtze River, and locally heavy to heavy rain; Hunan, Guizhou and other places have local freezing rain.
This round of cold wave will not only bring drastic cooling, but also bring a new range of rain, snow and freezing weather. Judging from the current situation, Hunan and Guizhou will suffer from freezing rain again, but the intensity of the freezing will not be as strong as the previous year. It is recommended that you continue to pay attention to the adverse effects of this round of rain, snow and freezing weather on transportation.
