Climatic characteristics of Dali Bai Autonomous Prefecture in Yunnan Province
Dali Prefecture is located in the low latitude plateau. Under the comprehensive influence of low latitude and high altitude geographical conditions, the monsoon climate characteristics of the low latitude plateau are formed: (1) the temperature difference between the four seasons is small. Close to the Tropic of Cancer, the solar radiation angle is large, and the variation range is small, resulting in a small annual temperature difference, and the climate characteristics of the four seasons are not obvious. "The qi of the four seasons is often like early spring, with cold ending and summer ending in temperature", and the temperature difference between the four seasons is not big; (2) The wet and dry seasons are distinct. Dali prefecture is dry in winter and rainy in summer. In winter (165438+1October to April of the following year), the rainfall in dry season only accounts for 5 ~ 15% of the annual rainfall, and in summer (5 ~ 65438+1October), the rainfall in rainy season accounts for 85 ~ 95% of the annual rainfall. (3) The vertical difference is significant. Due to the complex topography of Quanzhou, the altitude difference is great, and the vertical climate difference is remarkable. The temperature decreases with the elevation, and the rainfall increases with the elevation. The valley is hot, the dam area is warm, the mountain area is cool, the mountain area is cold and the three-dimensional climate is obvious; (4) There are many meteorological disasters. Due to the instability of monsoon circulation and the influence of different weather systems, there are many meteorological disasters in Dali Prefecture. Common meteorological disasters mainly include drought, low temperature, flood, frost, hail and strong wind.
