Can Northeasters adapt to the environment and climate when they go to college in Anhui?
Let me tell you something about the climate in Anhui.
First, the monsoon is obvious and the four seasons are distinct.
There are four distinct seasons in Anhui province, and the climate of "warm spring", "summer inflammation", "cool autumn" and "cold winter" is obvious. If we divide the four seasons according to the average climate temperature, the average climate temperature is < 10℃ in winter, > 22℃ in summer and 10-22℃ in spring and autumn, then the distribution of the four seasons in our province is roughly as follows: two months in spring and autumn, four months in Xia Dong, long in winter and short in spring and autumn. Because of the obvious climate difference between north and south, Huaibei is longer in winter than in summer, and Jiangnan is longer in summer than in winter. The start date of the season is from south to north in spring and summer, and from north to south in autumn and winter, with a difference of about 5- 15 days, with the largest difference in spring and the smallest difference in summer.
Second, the climate is mild and the rainfall is moderate.
The average annual temperature in Anhui province is between 14 ~ 17℃, which belongs to a mild climate type. In winter, the average temperature in 65438+ 10 is between-1 ~ 4℃, and in summer, the average temperature in July is around 28 ~ 29℃, which is lower than 30℃ all over the year, so the continental climate is not obvious. Except for a few years, the cold and hot periods are generally short. The annual precipitation in the whole province is between 750- 1700 mm, showing the characteristics of more in the south and less in the north, more in the mountains and less in the plains and hills. Huaibei is generally below 900 mm, Jiangnan, western Jiangnan and Dabie Mountain are above 1200 mm, and the rainfall lines such as 1000 mm run through the middle of Jianghuai hilly area. Precipitation in mountainous areas generally increases with height, and the average annual rainfall in Guangmingding of Huangshan Mountain reaches 2300 mm. From the national precipitation distribution map, the rainfall in our province is moderate, which can meet the needs of crop growth and development in general years.
Third, the spring temperature is changeable, and the autumn is crisp.
April and May are the transitional periods between winter wind direction and summer monsoon. The north-south airflow competes with each other, advancing and retreating freely, the front belt moves north and south, the cyclone activity is frequent, and the weather and climate are changeable. Therefore, cold and warm, rainy and sunny are a major feature of the spring climate in our province. The temperature rise in spring is unstable and changes greatly every day. The temperature in spring is lower than that in autumn, and the spring rain is more than the autumn rain. The precipitation in March, April and May accounts for about 20-38% of the annual precipitation, increasing from north to south. The rainy season in the south of the Yangtze River comes early, and the annual rainfall concentration period is in April, May and June. Spring rain is more than summer rain in Jiangxi, Tunxi and Qimen. In spring, the low temperature and abundant spring rains, especially the long-term low temperature and continuous rain, are unfavorable to the seedling growth of spring-sown crops such as early rice and cotton. In autumn, in addition to the cold high pressure on the ground, the subtropical warm high pressure is still maintained at high altitude, and the atmospheric stratification is relatively stable, and the autumn is crisp and sunny.
In autumn, the precipitation in September-165438+10 only accounts for about 15-20% of the annual precipitation, with little difference between the north and the south. Therefore, autumn drought and autumn drought often occur in various parts of Anhui Province. Several years later, in the process of summer monsoon retreat and winter monsoon strengthening, cyclones and fronts bring autumn wind and autumn rain, which is not good for autumn harvest and autumn planting.
