| 摘 要： | 基于贵州省黔东南地区1961―2008年1―12月16个台站冰雹观测资料,引入了表征冰雹事件时间分配特征新参数——冰雹事件集中度和集中期,对黔东南地区冰雹事件年内非均匀性特征进行分析。结果表明:黔东南地区冰雹事件集中度及集中期的平均和异常空间分布均存在很大区域差异,异常空间分布根据地形可分为4个区;从时间演变上看,各区年内冰雹事件集中度与集中期均表现出显著的年代振荡特征,各区年代际变化特征不一致;黔东南区域年内冰雹事件集中度和集中期表现出反向变化趋势。

| Abstract: | Based on the hail observation data of 16 stations in Southeast Guizhou from 1961 to 2008, the paper uses concentration degree (ECD) and concentration period (ECP) as two indices to analyze the inhomogeneity characteristics of hail events in the year in Southeast Guizhou. The result shows that the average and abnormal spatial distribution of ECD and ECP both have significant differences. By the topography, the abnormal weather spatial distribution of hail events can be designated as four regions. As for thei... |
