摘要: 利用1959-1993年冬半年(10月-次年3月)青南高原15个台站的月平均降水量和月平均气温距平资料,采用时空综合的经验正交函数分析方法,对青南高原地区冬半年降水、气温异常的时空分布特征进行了诊断研究,得到了降水与气温异常的典型配置及其反映这些典型场的年际演变规律的时间系数,并在此基础上进一步分析了降水、气温异常的时变特征与青南高原不同区域出现较严重雪灾年份之间的关系。结果表明,青南高原地区发生较严重雪灾的年份与时间系数出现极大(小)值的年份存在较好的对应关系。

Abstract: In this paper,by using the mean precipitation and air temperature anomalies data obtained from 15 observational stations in South Qinghai Plateau during the period of 1959-1993's winter half year,and with a joint-space and-time EOF method,a diagnostic study of the feature of spatial and temporal distribution of the precipitation and air temperature in South Qinghai Plateau is presented.Some typical patterns of precipitation and air temperature as well as the coefficients of their interannual variation are obtained.The results show that there is a good correspondence relationship between the severe snow disaster year in Sonth Qinghai Plateau and the extremum(maximum or minimum) year of the time coefficient.
Key words: The South Qinghai Plateau    Air temperature    Precipitation    Joint-space and-time    EOF method    Snow disaster in Plateau
