| 摘 要： | 采用4个月平均(11月~2月)代表冬季,根据陕西1951年以来53年的历史资料,应用地面月平均气温、月平均最低气温和月平均最高气温统计量,讨论了"冷"和"暖"冬季的标准,给出了1951—2003年陕西"冷"和"暖"冬季的划分及异常年份,最后给出了"冷冬"和"暖冬"的环流特征。

| Abstract: | The four months are chosen as the winter,i.e.November,December and the subsequent January,February.Based on the data of the last 53 years from 1951 to 2003,the mean monthly surface air temperatures,mean monthly maximun and minimun air temperatures are statistically analyzed,then discussed the standards of colder and warmer winters. the every winter from 1951 to 2003 are divided into normal-warmer-and colder-winters.Among them,extreme abnormal warmer and colder winters were put forward due to the deviation of these three statistic factors.Finally,the circulation characteristics corresponding to the colder and warmer winter were presented. |
