青藏高原积雪异常与贵州东、西部旱、寒灾害关系的初步分析

Analyses of Relationship between Anomalous Snow Cover over QinghaiXizang Plateau and Drought and Low Temperature Damage in Various Areas in Guizhou

利用 195 8— 1992年的有关资料 ,对青藏高原冬、春季积雪异常与贵州春、夏季不同区域干旱和低温灾害的强弱关系进行了统计分析。结果发现 :青藏高原冬、春季积雪异常与贵州春、夏季不同区域干旱和低温灾害的强弱间存在明显的相关关系 ,高原异常多雪年贵州西部 4月春旱偏重 ;东部夏旱偏重 ,春季低温灾害偏轻。反之 ,高原异常少雪年贵州西部春旱和东部夏旱都偏轻 ,春季低温灾害偏重。

The statistical relationship between anomalous snow cover over Qinghai\|Xizang Plateau(QXP) and intensity of the drought and low temperature in springsummer in various areas in Guizhou have been analysed by using of correlative data from 1958 to 1992. The results show that the correlation coefficient between anomalous snow cover over QXP and intensity of the drought and low temperature in springsummer in various areas in Guizhou was found to be quite apparent. The drought in springsummer in the various areas is stronger and the low temperature damage in spring is weak in Guizhou when the winterspring snow cover over QXP is more than the average years.The drought in spring\|summer in the various areas is slightly and the low temperature damage in spring is stronger in Guizhou when the winter\|spring snow cover over QXP is less than the average years. \ \
