What are the characteristics of the climate in Huxi County?

luxi county is located in the geolatitude plateau, and the vertical distribution of heat is obviously different, so it belongs to the northern subtropical monsoon climate zone. However, due to the complex terrain, there are actually three-dimensional climate types of subtropical and temperate zones. According to the heat standard analysis of accumulated temperature ≥1℃, there are five climate types vertically distributed in the county: south subtropical zone, middle subtropical zone, north subtropical zone, south temperate zone and middle temperate zone. From the alpine mountain area at an altitude of 2,2-2,46m to the mountain area at an altitude of 1,9-2,2m, from the dam area at an altitude of 1,3-1,9m to the valley area at an altitude of 821-1,3m, the climate is quite different, forming four climate types: cold, mild, warm and dry. The accumulated temperature in the valley area below 11 meters above sea level ≥1℃ is above 6℃, which belongs to the tropical climate of South Asia. At an altitude of 11-15m, the accumulated temperature of ≥1℃ is between 53-6℃, which belongs to the tropical climate of Central Asia. At an altitude of 1,5-1,8 meters, the accumulated temperature of ≥1℃ is between 4,25-5,3℃, which belongs to the tropical climate of North Asia. At an altitude of 1,8-2,2m, the accumulated temperature ≥1℃ is between 3,2-4,25℃, which belongs to the south temperate climate. In areas above 22m above sea level, the accumulated temperature of ≥1℃ is less than 32℃, which belongs to the middle temperate climate. [8]

The climate characteristics in the county are generally clear, wet and dry, rainy in summer and dry in winter. In addition to seasonal changes, there are local regional differences due to different altitudes and topography. Winter (dry season) is mainly controlled by westerly circulation, with less traffic, abundant sunshine, high temperature, less rainfall, low temperature, high wind speed and clear weather. Summer (rainy season) is mainly controlled by the southwest humid air flow, which comes from the Bay of Bengal in the Indian Ocean and is rich in water vapor, resulting in a lot of rainfall (sometimes influenced by the warm and humid air flow in the southeast Beibu Gulf). During this period, the weather is often cloudy, and the amount of solar radiation reaches the ground less. However, due to sufficient moisture, large evaporation and high heat consumption, the temperature will not rise very high. Therefore, the climate in the county is mild, with no heat in summer and no cold in winter. The annual temperature difference is large. The temperature is not high in summer, and it is vulnerable to low temperature and cold injury in autumn.
