Analysis of Distribution Characteristics of Thunderstorms in Hetian Area

Li Jing et al（Hetian Meteorological Bureau， Hetian， Xinjiang 848000）

Abstract This article uses daily precipitation data from 7 observation stations in the Hetian area from 1960 to 2020 and thunderstorm days from 7 observation stations in the Hetian area from 1960 to 2013. Analyze the daily precipitation data in the Hetian area， calculate the climate tendency rate， and study the distribution pattern of the percentage of days with different levels of precipitation and the variation of thunderstorm days. The results show that： （1） The Hetian area has sparse precipitation and belongs to an extremely arid desert climate. The precipitation was mainly concentrated in spring and summer from April to August， and the proportion of precipitation was the highest in light rain. （2） The frequency of thunderstorms in the Hetian area was consistent with the trend of precipitation frequency during its spring and summer seasons. Unlike the precipitation climate tendency rate， the frequency of thunderstorms in the counties （cities） where the 7 stations were located in the Hetian area is negative in the climate tendency rate， indicating a decreasing trend in thunderstorm days over time.

Key words Hetian region; Drought; Distribution pattern; Precipitation; Thunderstorm
