Analysis of Statistical Characteristics of Summer High Temperature in Hetian Area

Abdullah·Tohetijumai et al（Luopu  Meteorological Bureau， Luopu， Xinjiang 848200）

Abstract The historical meteorological data of 7 meteorological stations in the Hetian region from 1971 to 2021， with a maximum temperature of ≥ 35 ℃ for high temperature days， 35.0～36.9 ℃ for high temperature days， and ≥ 37 ℃ for high temperature days， were selected for analysis. The results showed that the total number of high temperature days in the Hetian region was 7 485 days. Its geographical distribution is obvious， mainly increasing from the middle to the east and west. The extreme highest temperature occurred in Moyu County， at 42.7 ℃， on July 16， 1973. In the past 51 years， the number of days with high temperatures ≥ 35 ℃ in the Hetian area has shown a weak upward trend of 1.068 d/10 a （P<0.10）， 0.142 d/10 a （P<0.10）， and 0.52 d/10 a （P<0.10） at 35.0～36.9 ℃ and ≥ 37 ℃. The Mann Kendall mutation test was used for mutation analysis of high temperature days， and the results showed that; The number of high temperature days with a maximum temperature of ≥ 35 ℃ experienced a sudden change in 2006， the number of high temperature days with a temperature of 35.0～36.9 ℃ experienced a sudden change in 1977 and 2006， and the number of high temperature days with a temperature of ≥ 37 ℃ experienced a sudden change in 2006.
