Who can tell me the weather in Hotan, Xinjiang?

Hotan area is deep inland, far away from the ocean, surrounded by high mountains (Tianshan, Kunlun and Pamir), and influenced by ocean airflow, it is continental. It is difficult to reach the cold and humid airflow from the west and the hot and humid airflow from the Indian Ocean. The southeast monsoon prevailing in eastern China is also difficult to drift because of its long distance. This area is located at low latitude, and the cold wave is blocked by Tianshan Mountain, so the temperature is high and it belongs to the extremely arid desert climate in warm temperate zone. Its main characteristics are: hot summer and cold winter, distinct seasons, abundant heat, large temperature difference between day and night and annual variation, long frost-free period, scarce precipitation, strong evaporation, dry air and obvious vertical distribution of climatic zones. In Kunlun area, the annual average temperature drops by 0.5 ~ 0.7 degrees Celsius for every 100 meter temperature increase.

Due to the large scope and area of the whole region, there are great differences in biology and climate under different landform conditions, which can be roughly divided into three climate types: southern region, oasis plain region and northern desert region.

Southern mountainous area: It includes the Qian Shan Valley area with an altitude of1800 ~ 3000m, and belongs to temperate or cold temperate climate zone. According to the meteorological data of Nurbangan (altitude 1970m) and Montenegro (altitude 1800m) in Qira County, the annual average temperature is 4.7℃, and the extreme maximum temperature is 34.0℃. The annual precipitation 127.5 ~ 20 1.2 mm, and the active accumulated temperature greater than 10℃ is below 3400℃, with short summer and long winter. The inversion layer is obvious in some areas, and the temperature in winter is 65438 0-2℃ higher than that in plain areas.

The climate in mountainous areas above 3000 meters above sea level is cold, and there are no four seasons, only the difference between cold and warm. The cold season is longer than the warm season, and the precipitation distribution is extremely uneven. The average annual precipitation is about 300 mm, and the growth period above 0℃ is 120 ~ 150 days. Above 5500 meters above sea level, it is a permanent snow belt below 0℃ all the year round.

In the oasis plain area, the basic characteristics of the four seasons climate are: long and windy in spring, hot and dry in summer, cool and fast in autumn, less snowfall and not cold in winter. It belongs to warm temperate zone and extremely dry desert climate. The annual average temperature is11.0℃ ~12.1℃, the annual precipitation is 28.9 ~ 47. 1mm, and the annual evaporation is 2198 ~ 2790 mm.

Northern desert area: The climate is very dry, with little rain, strong sunshine and drastic changes in hot and cold, mostly sand wind, which is a very typical continental desert climate area.

The accumulated temperature ≥0℃ in plain area is 4507. 1 ~ 4783.0℃, and ≥ 10℃ is 406.1~ 431.6℃. The accumulated temperature in desert areas is higher, such as the accumulated temperature of Hotan Tawakule ≥0℃ is 50000. For example, the accumulated temperature of Hotan Montenegro ≥0℃ is 2453.4℃, that of Hotan Montenegro ≥ 1865.2℃, that of Kangxiwa ≥0℃ 1090.3℃, that of ≥ 10℃ is 293.3℃, and that of sweet water sea.

The frost-free period in plain area is 182 ~ 226 days, mostly more than 200 days. The first frost period in desert and mountainous area is later than that in plain oasis area, such as Tawakule in Hotan, 200 ~ 2 10 day, and about 100 day in Montenegro.

There is little snowfall in winter, with an average snowfall of 6.3 days, an average snowfall of 3.6 mm, a maximum snowfall of 2 1 day and a snowfall of 23.2 mm, which is not cold in winter. The annual temperature is between 23 and 35℃, and the daily range is between 12.8 ~ 16.3℃.
