Falling into ambush on the 11th, it happened that the meteorological departments of Zhejiang and Shanghai also announced the plum blossom one following another. Once the rainy season is gone, the subtropical high pressure system will dominate. According to the perennial statistics, the three-volt period is the period when the Yangtze River Basin enters the main period of high temperature.
The high temperature situation on the 11th also reflected the north-south change very intuitively: the core area of high temperature shifted to the Yangtze River Basin. Many places in the Yellow River and Huaihe Rivers in North China withdrew from the ranks of high temperatures, while Sichuan, Zhejiang, Anhui and other places experienced high temperatures above 38°C.
Especially in Zhejiang, the temperature in most areas is above 37°C, and there are even large areas of extreme high temperature above 40°C in the central part.
With the rain coming,Before the 14th, the high temperature in Huanghuai in North China seemed to have weakened and paused, but the humidity increased and the body felt very stuffy.In Beijing, Tianjin, Shijiazhuang and other places, the highest temperature on the 12th dropped to regarding 30°C, and it was cool when it rained. Once the rain weakened or stopped, the humidity increased, and the body still felt stuffy and it was difficult to feel cool.
After 14 days,The high pressure on the mainland has strengthened once more, and it has opened up with the Iranian high pressure in the west. Xinjiang, the core area of the high-pressure system, will experience the largest and strongest high-temperature process this year.The high temperature in Xinjiang may reach its peak around the 15th.
For this round of high temperatures that started on the 14th, Turpan currently forecasts a maximum temperature of 44°C, while Aiding Lake in the hinterland of the Turpan Basin (which is also recognized as the lowest point on land in China, so the temperature will be higher), some numerical forecasts even give close to Extreme temperatures of 50°C.
Not only is it hot in the northwest, the rainfall in North China will end on the 14th, and it will return to the dry and hot sun exposure mode. Among them, Beijing, Tianjin, and Shijiazhuang will all have high temperatures for 3 to 4 consecutive days starting from the 14th.
Since the beginning of this year (as of July 10), the number of high temperature days in Beijing has reached 23. In addition to the two days of high temperature forecast on the 14th and 15th, it is only one day away from the highest record of high temperature days in the whole year (2000, 26 days). In addition, the highest number of high-temperature days in Tianjin is 27 days in a year, and there have been 22 high-temperature days this year, and 3 high-temperature days are forecast in the next 7 days.
For the south, the weather under the control of the subtropical high does not have many options.
heavy rainfall
In the next three days, the rain belt will move northward to the area north of the Yangtze River. There will be strong rainfall in the Sichuan Basin, the eastern part of Northwest China, North China, Huanghuai, Jianghuai, Jianghan and other places.The main rainfall period is from the night of the 11th to the 13th.
From the 12th to the 13th, the Sichuan Basin and the Huanghuai area will become two rainfall centers. The mountainous areas in Sichuan, Gansu, and Shaanxi should be alert to geological disasters, and the low-lying areas in the Huanghuai area should be alert to waterlogging.
On the 14th, the focus of rainfall shifted to eastern Inner Mongolia, Jilin, and Heilongjiang.
high temperature
In the core area of the subtropical high, long-lasting sweltering and high-temperature days will be the norm. Before the 14th, the subtropical high will remain strong, and a large area south of the Yellow River will continue to be sweltering, with body sensations above 35°C or even 40°C. Especially in Hunan, Jiangxi, Zhejiang, Fujian and other places, the highest temperature will reach 37~39℃.The lowest temperature may be close to or even reach 30 ℃, and the sweltering heat will last throughout the day.Wuhan, Shanghai, Hangzhou, Changsha, Nanchang, and Chongqing may also set new high temperatures this year.
When will it be hot in the south?
After the 14th, the cold air will move southward and the subtropical high will retreat eastward. The high temperature in the middle and lower reaches of the Yangtze River will begin to decrease, and the heat will ease. The high temperature in Hunan and Guangxi will decrease first. Hangzhou will withdraw from the high temperature ranks from the 15th.
However, the high temperature in Guangdong, Jiangxi, Fujian, and Zhejiang in the south and east will end later, and everyone will have to stay for a few more days…
From June 25th to July 11th in Fuzhou, there have been 17 consecutive days of high temperature, and the high temperature will continue from 12th to 16th. However, for Fuzhou, July is usually the month with the highest temperature in the year, with 15.7 days of high temperature in July.
