In the next ten days, Hunan high -temperature weather continues to interpret this year's rare high temperature weather

Hunan high -temperature weather has developed further. On August 15, the Provincial Meteorological Observatory issued a high -temperature red warning. It is expected that on the 16th, high temperatures above 39 ° C will occur in 12 cities and states in the province, and local areas will reach 40 ° C.

How much is the high temperature this year? What causes it? How long will it last for high temperature weather? On August 15, Xie Yijun, the chief expert of the Climate Forecast of the Provincial Climate Center, interpreted this.

High temperature weather history this year is rare

According to the monitoring of the Provincial Climate Center, since July 8th, Hunan Province has continued to be sunny and hot, high temperature and rainy weather, less rainfall, high temperature, and high temperature days. The second to 2013 is rare in history.

Among them, the average temperature of the province was 30.6 ° C, which was 2.0 ° C higher than the same period of the year. The average rainfall of the province was nearly 70 % less than that of the year. Hengdong, Hengnan, Shuangfeng, and Anren had no rainfall in nearly 27 days. The average number of high temperatures in the province is 28.4 days, which is 13.4 days more than usual.

Continuous high temperature and rainy weather has led to the rapid development of meteorological drought in Hunan Province. At present, 70 counties (cities, districts) in the province have reached the level or above. Among them, Jishou, Huayuan, and Anhua 19 counties (cities, districts) have heavy droughts, and special droughts have appeared in two counties in Cili and Xin Shao.

Why is it so hot this year

"The most direct reason is that the high temperature" perpetrator 'subtropical high pressure is extremely powerful, and the indirect reason is the result of the multi -factors such as the atmosphere and the ocean and the sea ice. " And the Luoji Mountains, rarely open up the entire northern hemisphere.

(The drought in Jishou City has developed rapidly.

"The indirect" initials "are human itself." Xie Yijun believes that the heat this summer is not local and regional, but is sweeping the world, which is closely related to the global warming caused by greenhouse gas emissions. The global accelerated warming broke the original balance of the atmospheric ring system. In this unstable climate background, once some abnormal factors are superimposed, such as the Lamina incident that is still continuing, it is more likely to trigger various extreme events.

High temperature weather continues in the next ten days

According to the forecast of the Provincial Meteorological Observatory, Hunan Province will still be controlled by the subtropical high -pressure in the next ten days. The high temperature and high temperature weather will continue. The maximum temperature can reach more than 40 ° C. Meteorological drought will increase rapidly.

Xie Yijun explained that in the context of global warming, high temperature and heat of this year will no longer be "extreme" or may become the norm.

In response to the continuous high temperature, Xie Yijun reminded that the continuous high temperature and drought weather should not affect the supply of hydropower supply, agricultural production, human health, and forest fire prevention.
