新疆北部冬季暴雪分布特征分析

Analysis of the Distribution Characteristics of Winter Snowstorms in Northern Xinjiang

摘要: 本文利用新疆北部多个气象站的长期降水资料，对新疆北部冬季暴雪的时空分布特征进行了深入分析。结果表明，新疆北部冬季暴雪存在明显的高频区和低频区，不同区域的暴雪时间分布也有所差异。同时，暴雪日数在年代际上呈现出一定的变化趋势，这与大气环流的变化密切相关。本文的研究结果对于了解新疆北部冬季暴雪的发生规律，以及做好相关的防灾减灾工作具有重要的参考价值。

Abstract: This paper uses long-term precipitation data from multiple meteorological stations in northern Xinjiang to conduct an in-depth analysis of the spatiotemporal distribution characteristics of winter snowstorms in northern Xinjiang. The results show that there are obvious high-frequency and low-frequency areas for winter snowstorms in northern Xinjiang, and the temporal distribution of snowstorms varies in different regions. At the same time, the number of snowstorm days shows certain interdecadal variation trends, which are closely related to changes in atmospheric circulation. The research results of this paper are of great reference value for understanding the occurrence patterns of winter snowstorms in northern Xinjiang and doing a good job in related disaster prevention and mitigation work.
