Since July 6, affected by high temperature, many places in China are in full swing, with high temperature above 35℃ in many provinces. At 8: 30 on July 8, China Meteorological Bureau launched a four-level emergency response to major meteorological disasters (high temperature).
Which areas are specifically affected by this round of high temperature process? How will the high temperature trend develop in the future? What are the defense suggestions? Fu Jiaolan, chief forecaster of the Central Meteorological Observatory and senior engineer at the research level, interprets them one by one.
High temperature above 35℃ occurred in 18 provinces (autonomous regions and municipalities).
The actual situation in the past few days shows that high temperature weather above 35℃ has occurred in parts of southern Xinjiang basin, eastern northwest, northern China, eastern southwest, Huanghuai, Jianghan, Jianghuai and eastern Jiangnan.
Fu Jiaolan introduced that since July 6, a total of 18 provinces (autonomous regions and municipalities) have experienced high temperature above 35 C, mainly distributed in Xinjiang Nanjiang Basin, central and western Inner Mongolia, Gansu, northeastern Qinghai, Ningxia, Shaanxi, central and southern Shanxi, Tianjin, central and southern Hebei, Henan, Shandong, Sichuan, western Hubei, Anhui, Jiangsu, Zhejiang, Shanghai and Fujian. Among them, the daily maximum temperature in some areas of Ningxia, central and western Gansu, central and western Inner Mongolia, central and southern Shaanxi, southern Hebei, western Henan, Sichuan Basin, central and eastern Zhejiang, Shanghai and southern Jiangsu even reached 37℃ to 39℃, and the local maximum temperature in Sichuan Basin, Shaanxi Guanzhong Plain, Hanzhong Plain and Ankang Basin exceeded 40℃. Fu Jiaolan said that the daily maximum temperature in Gansu, Ningxia, northeastern Qinghai, southwestern Shaanxi and Sichuan Basin has exceeded or reached the historical extreme value in the same period.
Precipitation will ease the high temperature in the north and the high temperature in the south will continue
On July 9, the Central Meteorological Observatory continued to issue a yellow warning of high temperature. It is expected that the high temperature in the above areas will continue, and the temperature in some areas will remain above 35 C.
So, how will the high temperature trend develop in the future? Is most of China still the "site" of subtropical high?
In this regard, Fu Jiaolan analyzed that from July 9 to 10, there were still high temperature weather in Xinjiang Nanjiang Basin, western Inner Mongolia, south-central Shaanxi, southern North China, Huanghuai and other places. After 11th, the high pressure in Iran has obviously weakened, and there will be a heavy precipitation process in northern China, which can alleviate the impact of this round of high temperature on the north.
However, in the next 10 days, the subtropical high will further extend to the west and lift to the north, controlling most of southern China. The high temperature weather in the south will further develop, and there will be continuous high temperature sunny and hot weather in the eastern part of southwest China, Jianghan, Jianghuai, Jiangnan and northern South China. Among them, the local temperature in Sichuan Basin and Zhejiang can reach above 40 C.
High temperature defense measures are indispensable.
In view of the current high temperature weather in many places in China, Fu Jiaolan said that high temperature weather will have adverse effects on power supply, water resources allocation, human health and agricultural production, especially in the middle and lower reaches of the Yangtze River and Sichuan Basin, where continuous high temperature weather occurs, attention should be paid to relevant preventive work. At the same time, Inner Mongolia, Shaanxi, Henan and other places also need to prevent the adverse effects of high temperature weather.
At present, it is the summer vacation. Fu Jiaolan reminds parents and students that if they have travel plans, they need to take measures to prevent heatstroke, guard against heatstroke, pay attention to weather forecast and early warning information in time, and make reasonable arrangements for travel.
