What are the strong climatic characteristics?

Dali Prefecture is located in the low-latitude plateau, and 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 among the four seasons is small.

Closer to the Tropic of Cancer, the solar radiation angle is large and the variation range is small, and the annual average temperature is12.2–18.9℃, which has the climatic characteristics of small annual temperature difference and unobvious four seasons. "The atmosphere of the four seasons is often like early spring, with Liang Yu ending in cold and the temperature ending in summer", and the temperature difference between the four seasons is not great.

(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.
