What month is the hottest in Jiangsu in summer?

General situation of temperature in Suzhou

According to the data analysis, the annual average temperature in Suzhou is 15.7℃, the highest is 1998 17.5℃, and the lowest is 1980 14.9℃, with an annual variation of 2.6℃. The hottest July, with an average temperature of 28.2℃; The most Leng Yue is 65438+ 10 month, with an average temperature of 3.0℃ and an annual average temperature of 25.2℃.

In spring (March-May), due to the enhancement of solar radiation, the temperature rises rapidly and the climate is mild. The average temperature is 14.2℃, and the monthly average temperature rises by 5℃, especially in April. However, due to the frequent exchange of cold and warm air in the middle and lower reaches of the Yangtze River, the temperature fluctuation is unstable, and the sudden cooling and sudden heating change greatly. In early April, there is often "cold spring" weather below 0℃.

Summer (June-August) is the hottest season in a year, with an average temperature of 26.6℃. It entered the rainy season in June, and the temperature did not rise significantly. After plum blossom in July, it entered midsummer, controlled by subtropical high, with the highest temperature, with an average monthly temperature of 28.2℃ and an average maximum temperature of 32℃, which is the hottest month in a year. Summer (June-August) accounts for 97% of the high temperature weather in summer, and the daily maximum temperature is > 35℃. The extreme maximum temperature was 39.2℃, which appeared on1July 29th, 992.

In autumn (September-165438+1October), the average temperature is 17.6℃. Due to the weakening of subtropical high, the temperature dropped month by month, and the temperature was still high in early September. In some years, the highest daily temperature in the first ten days of September is above 30℃, resulting in high temperature weather, commonly known as "autumn tiger", but it generally does not last long. Since mid-September, the main body of the Pacific subtropical high has rapidly withdrawn southward, the cold air has become increasingly active, and the temperature has dropped significantly.

Winter is the coldest season in a year, with an average temperature of 4.4℃ and 93% of the days when the daily minimum temperature is below 0℃. The middle and late June of 65438+ 10 is the coldest period in the whole year, and the daily minimum temperature is cold.

The distribution of annual average temperature varies with latitude, with a difference of 0.9℃ between north and south. In addition, there are two differences: First, the temperature regulation of Taihu Lake in the area along the lake is most obvious in winter. The average minimum temperature at Dongshan Station in Taihu Lake in June 5438+ 10 is 0.8℃ higher than that in the urban area and 1℃ higher than that in the northern counties (cities). This microclimate under the influence of vast water bodies has created favorable conditions for citrus and other fruit forests to overwinter safely along the lake. The second is the "urban heat island" effect in urban areas. Due to the nature of the surface, the industrial and commercial and population density in urban areas is different from that in suburban counties, thus forming an "urban heat island". The days with the highest temperature above 35℃ in summer in urban areas are 3.5 days longer than those in Wujiangduo 1. 1 day in the south and Kunshan in the southeast. The daily minimum temperature in winter is also high.
