Yesterday, Jiangsu Climate Center announced the climate impact assessment for this summer. The average summer temperature in the whole province this year is lower in the north and Huaibei, and higher in other areas. Average temperature in Huaibei in June 196 1 year minimum. However, judging from the number of hot days in summer, the number of hot days in summer this year is obviously less than that in other years of this century, especially in some stations in Huaibei area, which is rare in recent years. Generally speaking, this summer is the coolest since 2000. The sunshine hours in the province are obviously less than normal.

This summer, the province's heat island landed in Suzhou.

According to the statistics of the meteorological department from June to August, the hottest place in the province this summer is Suzhou, with an average temperature of 27.6℃; The coolest place is Ganyu, with an average temperature of 24.5℃. Compared with the normal period, the northern part between Jianghuai, Huaibei and Nanjing is 0. 1 ~ 0.8℃ lower. Suzhou and Kunshan are higher than 1℃, and other areas are higher than 0. 1 ~ 0.9℃. The days of high temperature in summer in the whole province are 0 ~ 19 days, and those in Liyang, Wuxi and Suzhou are 19 days. There is no high temperature day in summer in some areas of Huaibei. The average summer temperature in the province is 26.0℃, which is the same as the annual average temperature.

Ganyu is known as "Beidaihe, Jiangsu". The meteorological feature of this area is that it is very comfortable in summer. Among them, 196 1 year -2006, the average annual high temperature days in Jiangsu were 2- 10 days, and the average high temperature days in Ganyu were only 2 days. This year, the province's heat island landed in Suzhou, which also confirmed that the high temperature center in Jiangsu is constantly moving southward.

The hot summer sun is no longer "sinister"

Summer is always associated with sunshine, but the number of sunshine in the whole province is obviously less this year. This summer, Tropical Cyclone No.7 "Seagull" and Typhoon No.8 "Phoenix" successively affected Jiangsu, causing heavy rain in most areas of our province and heavy rain in some areas. Therefore, the precipitation in the north between Jianghuai, Huaibei and Sunan is more than normal1-60%. Too much precipitation also leads to less sunshine. This year, the sunshine hours in summer in the whole province are 307-575 hours, which is 1-50% less than normal. The average sunshine hours in summer in the province are 327.9 hours. The average sunshine hours in Nanjing in summer is 437 hours, 30% less than normal. There are many cloudy days and the sunshine is obviously insufficient. The impact is that the growth process of autumn crops is delayed, especially the heading and flowering of rice and the flowering and fruiting of cotton.

Too many people get sick after catching a cold.

Although Nanjing has not reached the meteorological standard of autumn, it is not hot in summer, and the temperature drops early in autumn, which also makes Nanjing citizens accustomed to hot summer a little unprepared. The reporter learned that since the end of August, the number of people in the hospital who got sick and hung up on water because they didn't adapt to the weather changes has increased significantly. Zhong Zhang Ai, director of the internal medicine department of Nanjing Hospital of Traditional Chinese Medicine, said that in recent days, colds, fevers, gastrointestinal discomfort and other diseases were largely caused by the summer heat.
