Xinjiang Climate Center: It is expected that the dry weather drought will continue to increase

Tianshan News (Reporter Xie Huixuan Report) The reporter learned from the Xinjiang Climate Center: Since the spring, the warm and raining in our district, the precipitation of more than 50 % of the precipitation in the eastern part of the Dongjiang area, the Changji Hui Autonomous Prefecture and other places; Little; in mid -May, drought elephants in the northern slope of Tianshan, eastern east, southern Xinjiang, and other places have continued to develop. At present, the mountainous areas of Changji and Northern Hami City have now heavy meteorological droughts. kilometer. It is expected that the meteorological conditions will still coerced the continuous and worsening of the meteorological drought. In response, experts from Xinjiang Climate Center suggested to improve the regulation of water resources in various places and take drought resistance early.

Meteorological drought refers to the phenomenon of shortage of surface moisture shortage due to the imbalance of dispersion and the income and expenditure of precipitation than the imbalance of the revenue and expenditure of the precipitation.

Data show that since the spring, most of the precipitation in our district is more than 20 % less than that of the year. There are more than many regions in north and south and northern Altay. There are 5-90 % less in southern Lenng Mongolia Autonomous Prefecture, especially in Hami, which is the first in history. Since the spring, the average temperature in Xinjiang is 2.2 ° C higher than the year, and it is the highest in history since 1961. The northern Xinjiang and East Xinjiang, eastern Hetian, and southern Bazhou are above 2 ° C. Since May, a total of 944 automatic meteorological stations in Xinjiang have appeared at high temperature (daily maximum temperature ≥35 ° C), which is the first time in history. The high -temperature weather process is extremely extremely extreme, and it appears earlier, strong and extensive compared with the perennial year.

According to the monitoring of the comprehensive meteorological drought index: in mid -May, the northern slope of Tianshan, southern Xinjiang (Hetian), and eastern East Xinjiang have continued to develop from mid -May; 2. For a long time of high temperature weather, the middle -severe meteorological drought occurred along the Tianshan area and the Aksu area in the northern part of Hami City in Tasari to Hami City. With an area of ​​330,000 square kilometers, severe meteorological drought occurred in Changji Prefecture, Hami and other places, and special droughts occurred in Fukang, Miquan, Bari Kun and other places.

The monitoring of the remote sensing vegetation index (NDVI) shows that compared with the same period last year in June 2022, the growth of ecological vegetation in Xinjiang is generally worse than last year. The growth of vegetation in the west of the northern Xinjiang Valley and other northern Xinjiang is better than last year.

It is expected that the temperature of the whole Xinjiang is generally higher or higher in the whole year (July -August); most of the precipitation in the whole Xinjiang is 20-50 % less. There are more; the number of high temperatures in Xinjiang is more than usual, mainly in July. In July, there will be 4 weak precipitation weather and 3 high -temperature weather alternately affecting North and South Xinjiang. The drought in north of northern Xinjiang may be alleviated; the meteorological drought in the east of our district, the Tianshan Mountains, and the Kunlun Mountains will continue and develop.
