Login tomorrow!Typhoon "Siaba" incarnates "sprinklers" in South China or existing extreme rainfall

Typhoon Siaba, No. 3 this year, approached step by step. Tomorrow (July 2) will land in South China, which will become the first typhoon to land in my country this year. The "Siam" has a strong rainfall ability, and extreme precipitation may occur in the local area. To this end, the Chinese Meteorological Administration has launched a three -level typhoon emergency response. How long will the "Siam" wind and rain affect? Why is it so strong with rain?

Typhoon orange warning Siaba may be the largest tomorrow to land in Guangdong

Typhoon Siaba No. 3 this year was generated yesterday morning. Yesterday, it was strengthened to a strong tropical storm yesterday. Landing in Wuchuan, Guangdong to Xu Wen will become the first typhoon that landed in our country this year. To this end, the Central Meteorological Observatory has issued a typhoon orange warning, and the China Meteorological Administration has upgraded to start a three -level emergency response.

Min Yuqiu, a meteorological analyst of China Weather Network, said that "Siaba" was born in the South China Sea and grown in the South China Sea. It is a typical "typhoon". The structure is asymmetric and weak in the first life, but the suitable sea temperature conditions in the South China Sea are enough to "Siaba" to draw energy, coupled with the strong monsoon of the South China Sea, and continuously sending water vapor and calories. Today, the "Siaba" wind wall has become thick. The spiral structure is also more clear and visible, and the intensity is significantly strengthened.

At 11 am this morning, Typhoon Avey "Avey" (tropical storm, level 8, 18 meters/s) in this year's Typhoon 4, will move north to the north, which will bring wind and rain on the East my country Sea in China. At present, there are two typhoons at sea, but the distance is far away and the mutual impact is small. (Picture: National Satellite Meteorological Center)

Under the blessing of favorable conditions such as high sea temperature, abundant water vapor, and small vertical wind cutting, it is not ruled out that "Siaba" will land with typhoon levels. "Such intensity is rare for the South China Sea's" Typhoon Typhoon "with a small development space and a short time." Min Yuqiu said.

Siaba may be alert to extreme rainstorms in Guangxi

"Quickly generating, immediately influence" is an important feature of "typhoon". This morning, the spiral rain belt of the cloud system of the "Siam" peripherals has brought precipitation to the coastal areas of Hainan and Guangdong. The core period of South China wind and rain is coming.

Due to the seasonal Feng Shui vapor transportation, the "Siaba" has a more prominent ability than wind and wind. Min Yuqiu said that South China will appear in the rainfall area of ​​heavy rain and above. , Guangdong, Guangxi and other places will undertake the most violent rainfall.

Hainan and Guangdong's heavy rains are mainly concentrated from July 1st to 3rd, and the heavy rainfall in Guangxi has continued from July 2 to the 6th. In addition, the rain and advantages of Guizhou, Yunnan and other places are also relatively strong.

The Central Meteorological Observatory predicts that from the 4th to the 4th, there will be heavy rains in Hainan Island, the coast of Guangdong and the west, and the central and eastern parts of Guangxi. The western and southeast of Guangxi are 250-400 mm, and the local area can reach 400 to 600 mm. From the 5th to 7th, there were heavy rains in Guangxi, Guizhou, Yunnan and other places, and heavy rain.

The typhoon process has a large amount of rainfall and has certain extremes. Min Yuqiu said that Wanning, Tunchang, Lizhou, Qiongzhong, Wuzhishan, Chengmai, Xu Wen, Leizhou and other stations may even approach or break the extreme value of precipitation in early July.

Why is the "Siaba" so strong? According to Min Yuqiu's analysis, it is mainly because of the support of the monsoon and the rotation after landing. "Siaba" is far from the subtropical high pressure and lacks a strong guide atmosphere. After landing, the "clip" is in the middle of the high -voltage and subtropical high pressure in the mainland. Long -term staying in Guangxi.

At present, it is the strongest period of the Southwest monsoon. After the "Siam" landed, its circular system is under a large amount of monsoon vapor, and it may bring extreme heavy rainfall to Guangxi in the future. However, because the "Siaba" path is still uncertain, we must continue to pay attention.

At present, due to typhoons, the Qiongzhou Strait has been suspended throughout the line, and the route from the beginning of the North Sea to Puzhou Island will also be suspended.

China Weather Network reminds that "Siaba" from generation to landing is not long, and the influence of South China "Dragon Boat Water" will be retreated shortly. There are many mountains and rivers in Guizhou, Yunnan and other places. In the past few days, geological disasters, small and medium rivers, floods, and floods in Guangdong, Hainan, Guangxi and other localities have high weather risks. Relevant departments and public need to strengthen prevention.
