The temperature in Wuhan on July 23rd, 2006 and August 20th, 2006.

The dog days in Jiangcheng this year were once as cold as autumn.

The lowest temperature in hot days is as high as 365438 0.6℃

Compared with last year, there are not many hot days in Wuhan this summer. Although there were two waves of heat waves and autumn tiger attacks, they didn't last long. After July 1 1, the first heat wave hit the middle and lower reaches of the Yangtze River, and Wuhan was hot for several days. On 13, the highest temperature in Wuhan first appeared at 38℃, and reached 39℃ on 14, and the lowest temperature on that day also exceeded 30℃. On June 6, 65438, the lowest temperature in Wuhan reached 3 1.6℃, setting a record for the lowest temperature in Wuhan since June 1907. According to Zhang Xuezhi, a senior engineer of Wuhan Meteorological Observatory, it is not uncommon to see continuous high temperature in Wuhan in summer, but it is rare for the lowest temperature to exceed 30℃.

Due to the hot weather, East Lake, indoor swimming pool, water park and riverside are all crowded, and people have jumped into the water to seek coolness. According to the person in charge of a swimming pool, the museum receives thousands of people every day these days. Nan 'anzui has also become a good place for citizens this year. According to reports, every night from 6 pm to 8 pm, the South Bank is crowded, and sometimes people are reluctant to leave until three or four in the morning.

According to experts, from the end of July to the beginning of August, the subtropical high controlled the Yangtze River basin, and a second heat wave appeared in Wuhan. During this period, the highest temperature in the blinds of Dongxihu Lake was 36.7℃, which was not as "compelling" as the first high temperature, but it also made the public feel stuffy.

In late August, subtropical high and continental high alternately "sit in the village", and "autumn tiger" appeared in Wuhan. On the 24th, the temperature in the louver was 36.4℃, and the high temperature came back again, which has continued to this day.

Sleep with a quilt on the dog days.

There are many cool days this summer, and many citizens are deeply touched, especially the rainy days in dog days, which are fresh in people's memory, so they are called "the coolest dog days in Wuhan".

After the second heat wave hit, in mid-August, the subtropical high retreated, the cold air in North China continued southward, and with the successive influence of typhoon 12 and tropical storm 14, low temperature and rainy weather appeared in Wuhan. Citizens wear autumn clothes when they go out to sleep at night. It is really cool for citizens to enjoy such cool weather in the "stove" Wuhan.

According to Zhang Xuezhi, a senior engineer of the Meteorological Observatory, in mid-August, the average temperature in Wuhan was 23.9℃, which was 4.3℃ lower than the historical period, the lowest value in the same period in the past century. However, the lowest temperature in August of 13 was 19.8℃, ranking second in the history of the same period in the past 40 years (the first place was 18.2℃ in 1980), and the highest temperature on that day was 210.4℃, which was also broken.

Although the cool weather makes people feel comfortable, it has a certain impact on the market. It is understood that due to the abnormal weather, it is undoubtedly a great disadvantage for clothing enterprises that rely on the weather to eat. The sales situation of shopping malls shows that the sales situation of summer clothes this year is not good, and there is no relatively concentrated "hot sale period".

Why is the weather abnormal this summer?

According to the data of Wuhan Central Meteorological Observatory, the average temperature in Wuhan in July was 29.2℃, which was 0.6℃ higher than the average temperature in the same period in history. The average temperature in August is 27.7℃, which is 0.5℃ lower than the historical average temperature. Generally speaking, the temperature in Wuhan this summer is relatively normal. According to senior engineers in Zhang Xuezhi, May to September is the flood season every year. From May to the end of August this year, the precipitation in Wuhan is about 670 mm, while the average annual rainfall is 700 mm.. According to Zhang Xuezhi, the rainfall this summer is still normal.

On the whole, although the temperature and rainfall are normal this summer, there are also "anomalies" in stages. July and August alternate between hot and cold, sometimes hot and sometimes cold. According to Zhang Gong, this situation is mainly due to the instability of the subtropical high in the western Pacific this year, which is swinging from north to south. At the same time, there are frequent typhoons along the southeast coast. So far, Tiffany. 17 has already appeared. Under this action, the climate law was broken.
