Will it really rain in the next 10 days, maybe 9 days? Does Beijing-Tianjin-Hebei still need snowfall?

On March 8, it can be seen from the Fengyun satellite cloud image that a large area of southern China is still in a rainy state, and the northern region is mainly sunny. At the same time, after the last wave of cold air, China is also entering a new round of warming. In the south of North China, the temperature will rise to more than 8 degrees in a large area, so it will heat up after a big cooling. However, when it is warming up, the new cold air in the north is already "ready to move". From the supercomputer's point of view, there will be a new wave of cold air on March 9.

So this is the development of warm current and cold air, which will inevitably bring some influence. Then the rain and snow weather is most obvious in some areas, especially in the north. At the same time, under the influence of cold air, the temperature generally drops by 6 ~ 8℃, and the local temperature can reach above 10℃, which is a relatively strong cooling. Moreover, after this wave of cold air, another wave of cold air starts from 12, so the temperature in the north is mainly "fluctuating" and the activity of cold air is relatively high.

Is it going to snow again in Beijing, Tianjin and Hebei? It is true that under the activity of cold air, Beijing-Tianjin-Hebei and central and eastern Inner Mongolia do have rain and snow weather according to the trend, but it may be more obvious in some mountainous areas, and it is mainly rain and snow weather, not pure snow weather. Secondly, there may be "pure snow" in northeastern Inner Mongolia and Heilongjiang, so even if there is snowfall, the scope and intensity are not as good as before. The forecast of the Central Meteorological Observatory does not show much. Under the influence of cold air, large area is also a small temperature fluctuation.

Now that it is spring, it is normal for the temperature to change strongly. When the snowfall changes with the seasons, it will be less and less. What can be explained here is that La Nina continues to develop, which may be related to the activity of cold air. Today, the central index of La Nina phenomenon remains below -0.5, indicating that it is still developing continuously. Therefore, we will continue to track the activities of La Nina phenomenon, and the activities that affect cold air are also affected by Arctic sea ice.

Let's look at the rainfall in the south. There is really too much rainfall in the south. On March 8, after small-scale rainfall in Guangxi, Guizhou and Hunan, the rainfall will be further expanded on March 9, and the rainfall intensity and distribution in the south will be upgraded. There are small to moderate rains in Guangxi, Guizhou, Hunan and Jiangxi, and there are heavy rains in some areas. By March 65438+.

According to the authoritative forecast of the Central Meteorological Observatory, the number of rainy days in the south can reach 6-9 days, which means that there will be 9 rainy or less rainy days in the south in the future 10. Just like "the sky leaks", there are still too many rainy days and a wide range. Although such rainy weather can't prevent the temperature from rising in a large area, it obviously has an impact on crop planting.

Spring rain is as expensive as oil? It is true that the spring rain is continuous. Sure, how long will it last? We can only continue to observe. Judging from the accumulated rainfall in the medium term, the accumulated rainfall in a large area in the south is between 25 mm and 50 mm, and there are also 100 mm to 250 mm areas in Guangxi, Hunan and Guizhou, so it is really strong.
