The cold air in South China is still lingering, and the whole country is warming up on a large scale. Will it be hot in March?

In March, the second wave of strong cold air has ended, and the whole country has entered a state of great warming, and it is very obvious that it is hot in the north and hot in the south, mainly due to the influence of the second wave of strong cold air, and many areas in the south still have the influence of "afterglow of cold air", so the temperature will not warm up so quickly.

According to the temperature in Guangzhou, Guangdong, the highest temperature was 30 degrees on March 20, and it dropped on March 22, and the highest temperature was 2 1.3 degrees, indicating that the afterglow of cold air is really affecting, and then it will slowly pick up.

At this time, the temperature rise in the north has come back, so the temperature fluctuation is the strongest in the north and not so fast in the south, which belongs to "slow rebound". Therefore, South China has experienced a wave of "spring" in a large area, but it will soon return to "summer". The highest temperature has risen to 29 degrees on March 26th, so it is very hot, which is an obvious state. Generally speaking, the northern region is now back to the state of great warming, at least in the central and eastern regions, and the south will be affected by the "cold air afterglow" for about two days, and then heat up.

Judging from this trend, there won't be too much rain and snow in China. From the perspective of supercomputers, it will also be "hot to the end" and there will be no new cold air activities. Of course, changes can also occur in the future. We can see that new cold air activities are expected at the end of March. At the end of March, cold air mass activities can be seen in the northwest region, which has brought temperature drop to Xinjiang and other regions. So if we look at the whole country, this year's cold air is not over yet, but the intensity is not as strong as winter, so we will continue to observe.

However, we say there won't be much rain and snow in a short time. According to the trend, it will pick up in March. In fact, rainfall still exists in the southern region, and it is expected that there will be two more waves of rainfall before the end of March. It is predicted that there will be a continuous rainfall process on 25-28 and 29-3 1 day, which is equivalent to lasting from March 25 to the end of March, but this will not affect the climate phenomenon of great warming. At the same time, many places are also expecting a wave of rainfall development. Because it seldom rains in many areas now.

It can be seen from the national meteorological drought monitoring map that there is less rain in Yunnan, Sichuan, Guizhou, Guangdong, Guangxi and Fujian. The most water-deficient place may be Yunnan, where there has been a large area of drought, so rainwater development is needed. Can this wave of continuous rain be alleviated? On March 25th, there was little rain. On March 26th, rainfall in the Yangtze River basin increased, with moderate to moderate rain in Anhui, Henan, Hubei, Hunan and Chongqing, and then it will expand, with moderate to heavy rain in the Yangtze River Delta.

So at least from the current situation, there is still no rainfall development in Yunnan and most parts of South China, mainly concentrated in Jianghan, Jianghuai and Jiangnan, which is the next rainfall development. On the whole, it is true that today's climate change is quite complicated. Although the temperature has risen in a wide range, the "spring rain" in the south is still in a state of "spring rain is as expensive as oil", which is much less than that in the south. This is the general situation. Let's continue to follow up on climate change, and this year's climate state may be more complicated.

But now the sea area is still relatively stable. After 202 1 and 1 typhoon rhododendron disappeared, although new tropical disturbances developed and typhoon embryos were formed, they eventually disappeared. So this year's No.2 typhoon was delayed, and a typhoon appeared behind it. Let's take a look at the situation again.
