It's really a hearty chill!
I used to feel very powerful when I dropped down by 8-10, but who would have thought that now the temperature will start at 20, and I will really see you for a long time!
At 14 o'clock today, in central Guizhou, northern Guangxi, northwestern Guangxi, southern Jiangxi, western and northern Fujian, and southern Zhejiang, there was a cliff-like cooling, with a general drop of more than 20!
The picture above shows the ranking of the 24-hour temperature change at 14 o'clock today, and the temperature drops by more than 25 in a day to qualify for the top ten. For example, at Libo Station in Guizhou's Qiannan Buyi and Miao Autonomous Prefecture, the highest temperature exceeded 30 yesterday, reaching 321, only 4 at 14 o'clock today, falling directly from summer back to midwinter.
There is also Fuzhou, Fujian, where the maximum temperature soared to 32 yesterday3, not only refreshed the local record of the highest temperature extreme in February, but also refreshed the earliest time of local 30+ appearance! However, the temperature dropped all the way today, and by 14 o'clock in the afternoon, the temperature was only 132. Short-sleeved thick jacket, just one night.
The first cold wave of the Year of the Dragon not only crossed the Nanling Mountains, but even "penetrated" Guangxi, and the Hepu, Fangchenggang, Qinzhou and other places along the southeast coast of Guangxi also saw a significant cooling of 5 12!
Yesterday was still full of short-sleeved streets in Nanning, Guangxi, and today I saw the figure wearing a down jacket again.

Indeed, the weather is becoming unfamiliar. Today @Hunan Weather said that this cold wave is the strongest cold wave for Hunan in the past 50 years.
Why is this cold wave so strong?
The strength of the cold air itself is one thing, but the unusually warm air before it arrives is also worth paying attention to. It is precisely because it was too much warmer in the early stage that the temperature was pulled to a very ridiculously high level, which reserved a very large space for the cold air to cool down later.
In fact, looking at the temperature changes, it can also be seen that more than half of the 20+ cooling range in many places in the south is "correcting" the previously ridiculously warm temperature.
Taking Changsha as an example, the highest temperature on February 18 before the cold wave came was 292, more than 17 higher than the same period in normal years. (Note: The average maximum temperature in Changsha in mid-February is only 11.)9℃。After the cold wave came to cool down, the temperature in Changsha has dropped below freezing this afternoon. From the high point of the process temperature to the low point, the cumulative cooling range has exceeded 30, and more than half of this is the ...... of the previous warm "correction".
Seeing this, everyone can also understand that the warmer it is, the more likely it is that we will encounter more outrageous cold waves in the future. Of course, there is also the impact of climate warming on the intensity of cold air in winter in China, so I will not expand on it here.
Back to the present, after the cold wave arrives in South China, it also means that it is about to enter the end of the impact. After the cold air southward momentum weakened, the impact on Hainan is not great, in addition, Yunnan also has Wumeng Mountain block, Kunming temperature in the future is still stable and rising, therefore, in the future, Haikou and Kunming will be one of the few cities with warm temperatures.
The weather in Kunming is really good, the temperature is suitable, and it is sunny.
Judging from the medium-term forecast of the ** Meteorological Observatory, in the next 10 days, except for the average temperature in southern China and eastern Yunnan, which is 2 4 higher than that of the same period in normal years, the average temperature in most of the rest of China is lower than that of the same period in normal years1 3.
Specifically, the overall temperature in many places in the north today and tomorrow is still significantly low, but the cold has eased, and the temperature has gradually bottomed out. Among them, from the 24th, the rain and snow in the north will weaken and stop, and there will be an interval of about 4 days of precipitation.
For many places in the south, there will be a significant reduction in the heavy snowfall tomorrow, but after this round of rain and snow, the precipitation will not be completely over. From Guizhou to the south of the Yangtze River, the rainy and snowy weather lasted almost until the end of this month, so the temperature in many places from the middle and lower reaches of the Yangtze River to Guizhou will continue to be low, and the temperature in some areas will continue to be low8.
In addition, in eastern Guizhou, Hunan, eastern Hubei, southern Anhui and other places, there will be freezing rain tomorrow and the day after tomorrow, and it is necessary to pay attention to road conditions and driving safety through Erguang, Shanghai-Kunming, Hangrui and other expressways.
