【摘要】 利用青藏高原积雪深度资料分析了青藏高原冬季１月平均积雪深度与云南夏季气温、降水的联系。结果表明：青藏高原冬季积雪与云南夏季气温和降水有较好的联系，即青藏高原冬季１月积雪峰值年对应云南北部７～８月气温低谷年，云南夏季易出现“８月低温”天气；青藏高原积雪多的年份，昆明夏季６～８月降水异常偏多，云南大部７月降水异常偏多，云南哀牢山脉以北、以东地区８月降水异常偏多。５００ｈＰａ异常环流分析表明，冬季青藏高原积雪多的年份云南夏季对流层中部冷空气活动较频繁，冷空气与底层西南夏季风暖湿气流交汇，可使降水异常增多更多还原

【Abstract】 The relationship between the snow cover of the Qinghai Tibet Plateau and the temperature and precipitation in summer in Yunnan Province is studied.The Result shows that the peak of annual array of depth of snow cover corresponds to the low temperature of Yunnan in summer and that the more the snow cover,the more the precipitation in June at Kunming in July at the most of Yunnan and in August North East of Ailaoshan mountain range.The analyses of 500hPa circulation show that during more snow cover year cold air activities are strengthened in Yunnan.更多还原
