对蒙古冬季降雪异常及其相关的大气环流进行了观测研究。采用1940年至1992年蒙古23个站点的月度积雪深度和气温数据进行统计分析。蒙古族雪量北部山区较多，向南逐渐减少。平均而言，11 月和 12 月期间积雪深度会出现季节性大幅增加。最深的降雪发生在 1 月份，所有 23 个站点的平均深度为 3.4 厘米。 11月和12月雪深与气温的相关系数在大范围内显着且负相关。
An observational study was conducted of winter snow anomaly in Mongolia and the associated atmospheric circulation. Monthly data of snow depth and temperature at 23 Mongolian stations from 1940 to 1992 were used for a statistical analysis. The Mongolian snow amount is fairly large in the northern mountainous regions and decreases to the south. On average, there is a substantial seasonal increase in snow depth during November and December. The deepest snow occurs in January, with an average depth of 3.4 cm averaged for all 23 stations. The correlation coefficients for November and December between the snow depth and temperature are significant and negative over wide areas.
