What are the climatic characteristics of Diqing Prefecture?

The climate characteristics of Diqing Prefecture are mainly controlled by the southwest monsoon and the southern branch of westerly jet, with distinct dry and wet seasons. From June to 65438+10, affected by southwest warm and humid airflow, there are many rainy days, and the rainfall accounts for 80% of the annual rainfall, forming a wet season. From June 1 1 to May, under the control of westerly jet, a dry and warm southern branch, the rainfall only accounts for 20% of the annual precipitation, with many sunny days, abundant sunshine and large evaporation, forming a dry season. The mountains in the county are high and the valleys are deep, and the climate changes with altitude. From the Donghe Valley in Jinsha at an altitude of1.503m to the Haba Snow Mountain at an altitude of 5,396m and the top of Shan Zong in balague at an altitude of 5,545m, there are six climatic zones, namely, the North Subtropical Valley, the Warm Temperate Mountain, the Temperate Mountain, the Cold Temperate Mountain and the Subtropical Mountain. The climate is wide and narrow. One mountain is divided into four seasons? Typical stereoscopic climate.

The county seat is 3 degrees and 25 minutes away from the Tropic of Cancer. The plateau mainly built in Tang Zhen and Xiaozhongdian Bazi has an average elevation of 3,450 meters. The solar projection angle does not change much throughout the year, and the acceptable solar radiation energy is sufficient throughout the year. There is little seasonal difference between sunshine hours and total solar radiation, and the annual temperature difference is small. There is no summer all year round. The annual average temperature in the plateau dam area is 5.5℃, and the average temperature decreases with the elevation. The annual average temperature 14~ 17℃ in the valley area at an altitude of 1500~2 100 meters, and 8~ 14℃ in the mountainous area at an altitude of 2100 ~ 3000m. From the river valley to the plateau dam area, it decreases upward at 0.64℃/ 100 m in the south and 0.88℃/ 100 m in the north. Above the plateau, it gradually decreases by 0.6~0.7℃/ 100 m. The extreme low temperature in the plateau dam area 1958 ~ 2000 was-16.4~-27.4℃, with an average of -20. 1℃, and the extreme minimum temperature was -27.4℃, which appeared on1June 27, 1982. The extreme maximum temperature was 26.6℃, which appeared on1June 28th, 988. However, the transparency of the air layer on the plateau is high, and the solar radiation is stronger than that in low altitude areas of the same latitude. The temperature rises sharply during the day, drops sharply at night, and the daily temperature difference is large. In the dry season, the daily temperature difference reaches 30℃. Can describe? There are no four seasons in a year, and there are four seasons in a day? The climate characteristics of the plateau are very obvious.

The terrain of this county is low in the south and high in the north. The south bears the brunt of the warm and humid air flow, with relatively abundant precipitation, humid climate and relatively dry north. The precipitation in China increases with the elevation. With the increase of altitude 100 m, the precipitation increases by 20~40 mm, and the maximum precipitation height appears in the area of 3400~3600 m above sea level, and the precipitation reaches 1000 ~ 1200 mm. The rainfall distribution is bounded by the construction of ponds and dams, and the southeast mountainous area is 800 ~1. The northwest mountainous area is 400~600 mm, and the valley is 300~400 mm. In addition, the terrain structure of our county is complex and various climate types are intertwined. In the same vertical climate zone, there is a single small topographic climate such as forest climate, grassland climate and lake basin climate, which forms? Every other day. Different day? The climatic characteristics of.

Geographical environment, location and territory of Diqing Prefecture

Diqing Tibetan Autonomous Prefecture is located in the northwest of Yunnan Province, at the junction of Yunnan, Tibet and Sichuan provinces, with a total area of 23,870 square kilometers. It borders Xizang Autonomous Region in the northwest, Sichuan in the east, Lijiang in the southeast and Lisu Autonomous Prefecture in Nujiang in the west. The highest altitude in the territory is 6740m at Kawalpo, the main peak of Meili Snow Mountain, which is also the highest in Yunnan Province. The lowest altitude is the Lancang River Valley, with an altitude of 1486m and an absolute height difference of 5254m. The huge height difference in a small area makes the territory have vertical climate and three-dimensional ecological environment characteristics. Diqing Tibetan Autonomous Prefecture is the highest and only Tibetan Autonomous Prefecture in Yunnan Province. Shijiantang Town, Shangri-La, where the state capital is located, is 608 kilometers away from Kunming, the provincial capital.

topography

Diqing Tibetan Autonomous Prefecture is located in the southeast edge of the Qinghai-Tibet Plateau and the hinterland of Hengduan Mountains.
