| 摘 要： | 利用中国强沙尘暴序列及其支撑数据集,分别以站日和站时为计算单位,建立了中国50 a(1958-2007年)沙尘暴时间序列,分析了两个序列的关系,并比较了两者所反映出的沙尘暴时空变化特征。结果表明,站日和站时序列总体变化趋势比较一致,但细节有所差别,有时会影响某些结论。在反映沙尘暴的时间变化和空间分布时,两者存在明显的差异。

| Abstract: | Base on observation data from meteorological stations,two time series of sand-dust storm(SDS) occurring in China during 1958-2007 were established by using the station-day and station-hour as units,respectively.The relationships between the two time-series were investigated and the characteristics of the temporal and spatial variations of SDS were analyzed and compared.The results indicate that the overall variation trends of SDS station-day and station-hour are consistent,but there are differences in detai... |
