How did the Beijing Tianjin Hebei region become a "furnace"?, Starting from the 27th, high temperatures will reappear | Huanghuai | Furnace
On the first day of work after the holiday, the high temperature weather in North China, Huanghuai and other areas has weakened, and the Central Meteorological Observatory has lowered the orange high temperature warning to a yellow warning. But starting from the 27th, there will be another heatwave in North China, Huanghuai, Fenwei Plain and other areas.
According to statistics, the average temperature in China from the 22nd to the 24th was 31.6 ℃, with a maximum temperature of 41.8 ℃. Among the national meteorological stations, there are 1590 with temperatures reaching 30 ℃ or above, accounting for 64.69%; 370 have reached 37 ℃; There are 130 that reach 40 ℃.
From the 21st to the 24th, the high temperature weather in the Beijing Tianjin Hebei region developed rapidly. The highest temperatures in Beijing, Tianjin, central southern and northeastern Hebei reached 38 ℃ to 41 ℃, with 14 national meteorological stations exceeding historical extremes and 37 stations exceeding the same period in June. The highest regional temperature occurred on the 22nd at Tanghekou Station in Huairou District, Beijing and Dagang Station in Binhai New Area, Tianjin, both reaching 41.8 ℃. The area affected by high temperatures above 37 ℃ is approximately 165500 square kilometers, and the area affected by temperatures above 40 ℃ is 70000 square kilometers. The comprehensive intensity level of the regional high temperature weather process is particularly strong.
According to Zhang Fanghua, the chief forecaster of the Central Meteorological Observatory, the recent high temperature weather is mainly caused by the strong control of warm air masses in North China, Yellow and Huaihe regions, and the impact time is relatively long. At the same time, under the control of high-pressure ridges, the sky is clear with few clouds, and the increase in solar radiation promotes heating. In addition, during the summer solstice, the daylight is longer and the sun shines for a longer period of time. In addition, the low humidity and dry weather in North China, Huanghuai and other regions are conducive to temperature rise and high temperature maintenance.
Many members of the public have doubts: how has the Beijing Tianjin Hebei region become a "furnace" when it is so hot before the fall of the summer?
In fact, there are significant regional differences in the concentration of high temperatures in various regions of China. The southern regions usually enter the hot season during the midsummer period, while the northern regions often enter the early summer period.
"For the North China region, high temperatures are usually more likely to occur from June to early July before the rainy season, and consecutive days of high temperatures are also more common in June. This period is mainly characterized by dry and hot temperatures, characterized by high temperatures and low humidity." Gao Hui, chief forecaster of the National Climate Center, said that under the background of global warming, the frequency of extreme high temperatures occurring in both the south and north is increasing.
The Central Meteorological Observatory predicts that from the 27th to the 30th, there will be another heatwave in North China, the Huanghuai River, the Fenwei Plain, and other areas. At that time, some areas in Beijing Tianjin Hebei, Shandong, Henan, Inner Mongolia and other regions will be at risk of high temperature disasters. Experts remind that continuous high temperatures will increase the risk of heatstroke or heat stroke, and outdoor activities and workers should take good health protection measures; At the same time, the demand for energy is increasing, and it is recommended that relevant departments ensure the supply of water and electricity.
