Typhoon ＂Taili＂ may become the first landing typhoon this year, and the high temperature in South China and other places will ease.

　　Cctv newsAccording to @ China Weather Network Weibo, a tropical depression occurred near the Philippines at 11: 00 this morning (July 14th). It is expected that this tropical depression will strengthen into the 4th typhoon "Taili" this year, and will affect or land on the south China coast early next week, which may become the first typhoon to land in China this year. What are the characteristics of Typhoon Taili? What will be the impact? @Walle Hu Xiao, Chief Meteorologist of China Weather, explains it for you.

　　Typhoon Teli may become the first landing typhoon this year, about 20 days later than normal.

　　Since mid-June, the tropical ocean surface in the northwest Pacific Ocean and the South China Sea has been controlled by subtropical high, which has suppressed convection activities and lacked the necessary conditions for typhoon formation, forming a typhoon blank period of more than one month. With the retreat of the subtropical high eastward, a tropical depression near the Philippines has been generated today, which will soon develop into the fourth typhoon "Taili" this year, which also indicates the arrival of an active typhoon period.

　　"The future typhoon ‘ Terry ’ It has the characteristics of stable westbound, offshore strengthening, and advantages and disadvantages. " Hu Xiao, chief meteorologist of China Weather Network, said, "From the trend, it is more likely to travel westward in the northern part of the South China Sea, gradually affecting South China."

　　At present, the tropical depression will soon cross the Philippines and enter the northern part of the South China Sea with a SST of about 30℃. In addition, the monsoon support on the south side of the tropical depression is relatively strong, which has good conditions for development and enhancement. In addition, the outflow conditions at the upper level are also good, which may reach the level of typhoon to strong typhoon. Friends in coastal areas of Guangdong and Hainan need to be alert to the rapid increase of typhoons in the offshore areas.

　　According to the current forecast, "Taili" will land in the western part of Guangdong to the northern coast of Hainan on the 17th, becoming the first typhoon to land in China this year, and the landing time is about 20 days later than the average landing time of the first station in normal years (1991 -2020) (June 27th). After that, it will continue to move westward and may land in Vietnam. Hu Xiao added that there will be a tropical depression system going northward behind "Teli", which may affect the landing time of the typhoon, and it is necessary to continue to observe.

　　At the beginning of next week, it will enter the core period of typhoon impact, and the high temperature in South China and other places will ease.

　　From the impact point of view, there will be stormy weather along the coast of South China from the beginning of next week, and next Monday and Tuesday will be the core impact periods, with heavy rains in some areas such as Guangdong and Hainan. At present, the sea surface temperature conditions in the coastal areas of South China are very good, and the development of typhoons is easy to exceed expectations. The coastal areas of western Guangdong and Hainan need to be alert to strong winds and waves.

　　On the positive side, the wind and rain it brings will temporarily alleviate the hot and muggy weather in South China, such as Guangzhou, Shenzhen and Haikou, where the underground temperature will drop for two to three days on Monday and Tuesday, and the heat will be relieved. However, before this, the high temperature in South China will be enhanced, so it is necessary to pay attention to heatstroke prevention. In addition, when this tropical system affects South China, low pressure or inverted trough will also develop on its north side, which will bring rainfall and cooling to East China and temporarily ease the hot weather.
