What does the disappearance of South Pacific 17 tropical cyclone "Harold" mean?

After the tropical cyclone "Harold" in the South Pacific 17 or above disappeared, the world can be said to have entered a new "storm window period". After the code was cancelled, new storm embryos appeared in the marine area, which were "double storm" embryos with codes 93S and 94S respectively. As can be seen from the codes of these two storm embryos, they are really not balanced in the northwest, so

According to the meteorological data in Europe and America, 93S is located at 10. 1 S 90.8 E, the maximum wind speed is 20 kt, the minimum central pressure is 1007 hectopascals, 94S is slightly weak, the center is located at 8.0 S 74.0 E, and the maximum wind speed is 15 kt, so,

Of course, whether the brewing of the "double storm" will affect some areas will be seen later. For the time being, from the satellite images, they are all located in the central area of the ocean, and we will observe them later. It can only be said that the brewing of storms is normal in different sea areas around the world, which is the situation of the whole sea area. The Pacific Northwest is very stable now. Let's take a look at a change in the land area of China.

On the whole, China can be said to be a large-scale sunny mode, but there is still a small range of cold air and rainfall. From the development of cold air, it mainly affects South China, Yunnan and other places. According to the data of the Central Meteorological Observatory, the temperature drop in some areas can reach above 8℃, so it is a little cold.

It can also be seen from the weather analysis chart that there is an obvious development of "cold high pressure" in northwest, north and south China. Therefore, this is also a manifestation of influence. Of course, there are also low-pressure areas in western Yunnan, but this is only a short-term situation, because there may be rain next. According to the forecast data of the Central Meteorological Observatory, from 12 to 13, there are moderate rains, local heavy rains or heavy rains in parts of northern and southwestern Yunnan.

So this can alleviate the long-term lack of rain in some parts of Yunnan. Now it has entered a wide range of fine weather, but it is worth noting that a new wave of large-scale rainfall may come again. According to the forecast data of the Central Meteorological Observatory, 17- 19 will see a large-scale precipitation process in the central and eastern regions of China.

So it will rain for three days. According to the forecast coverage map around 8: 00 on April 17, there are obvious moderate to heavy rains in Guangxi, Hunan, Guizhou, Hubei, Chongqing, Sichuan and other provinces, and there are heavy rains in some areas. By about 18, the rainfall will spread to East China, and the main rainstorm area is mainly in Hunan, with a larger range of moderate to heavy rain. On June 5438+09, the rain was a little scattered, but there was rain later, so there was still a lot of moderate to heavy rain in these three days. At the same time, we need to pay attention to the development of strong convective weather, which may be accompanied by thunderstorms or hail. This is a new rainfall forecast.

Judging from the rainfall forecast of the Central Meteorological Observatory in the next week or so, the range from 50 mm to 100 mm in Guangxi, Guizhou and Hunan is indeed quite a lot, which also shows that there is indeed more rainfall in the south. Now most of southern China has entered the flood season. At the same time, according to the preliminary forecast data, major floods may occur in the middle and lower reaches of the Yangtze River, the Xijiang River and Haihe River in the Pearl River Basin, the Songhua River and some water systems in Zhejiang and Fujian this year, which reminds us that there may be more rain this year, so we should always pay attention to preventing the impact of rainfall.
