Chenzhou City is located at the northern foot of Nanling Mountain, in the subtropical climate zone of 24 53 ′-26 50 ′ north latitude, and its terrain is inclined from southeast to northwest, showing a "mountain" shape, which is high in the east and low in the west, high in the south and low in the north. Several main mountain systems of Nanling Mountains run northeast-southwest in Chenzhou, which block and lift the cold air from north to south, and act as a barrier to the warm and humid airflow from southwest, so that the climate of Chenzhou City has obvious local microclimate characteristics in addition to the main characteristics of subtropical humid climate. That is to say, it has the characteristics of light, heat and water in the same season, and the four seasons are clearly coordinated, and there is also a microclimate with high temperature in the south and low temperature in the north, low precipitation in the west and high temperature in the east, few warm areas in Pingshan, and concentrated precipitation due to local topography. Controlled by Mongolian high pressure in winter and spring, the continental monsoon in the north prevails in Chenzhou city, with more cold air activities; Summer and autumn are controlled by the western Pacific subtropical high and Indian low, and the tropical maritime humid monsoon prevailing in the south is characterized by hot Leng Xia in winter, abundant spring rain, long high temperature period in summer and crisp autumn, but sometimes continuous autumn rain and diverse mountain climate.
Chenzhou has four distinct seasons, with long winter and summer and short spring and autumn in hilly areas. Winter is long in mountainous areas, and spring, summer and autumn are short. In flat hilly areas, from winter to spring and from spring to summer, the south is 2-4 days earlier than the north.
Spring precipitation is the most frequent season in a year, accounting for 37.3% of the annual precipitation. The sunshine hours are 220-290 hours, and the distribution characteristics of sunshine hours are less in the south and more in the north.
The most remarkable features of spring climate are early spring, rapid temperature rise, abundant precipitation, rainy weather and hail and strong wind.
The hot summer climate is prone to midsummer drought, heavy rain and floods. Because the average altitude is over 400 meters, hilly areas and mountainous areas are cooler than neighboring cities. The cool climate in mountainous areas is more prominent.
Autumn in Chenzhou is dominated by crisp air, with strong sunshine, less precipitation and more sunny days, which is prone to autumn drought. In a few years, autumn rain will be accompanied by cold dew wind.
Winter climate is characterized by less cold, less rain and snow, and the temperature is higher than that of surrounding cities.
The coldest month in a year is 65438+ 10, with an average temperature of 6.5℃, and the hottest month is July, with an average temperature of 27.8℃. With the arrival of spring, the temperature rises rapidly in March and April. After midsummer, the temperature drops. From September to 65438+February, the temperature drops by as much as 5℃ every month to enter winter. It reflects that Chenzhou belongs to continental climate.
