| 摘 要： | 利用贵州52个测站的1961-2006年历年夏季（6-8月）逐日降水资料，分析了贵州夏季暴雨的时空分布特征、周期振荡及其突变特征。结果表明：46 a来贵州夏季暴雨量呈增加趋势，并存在明显的年际、年代际变化特征；暴雨日数和暴雨量在1985年发生突变；暴雨日数和暴雨量均存在15 a和准10 a的周期振荡；暴雨日数和暴雨量EOF分解的第一特征向量的荷载场空间分布基本一致，表明全省呈偏多（少）的一致型同位相分布。 |

| Abstract: | Based on the daily precipitation data in summer (JJA) for the period from 1961 to 2006 at 52 observation stations, temporal and spatial characteristics, periodical variations and abrupt changes of summer rainstorm in Guizhou were investigated. The results indicate that rainstorm precipitation increased in the past 46 years and its interannual and decadal variations were remarkable . The abrupt changes in the rainstorm precipitation and day number both occurred in 1985. There were periodical variations of 15 years and quasi-10 years in both summer rainstorm precipitation and day number. The first EOF eigenvector field of summer rainstorm day number was consistent with that of summer rainstorm precipitation, showing consistent in-phase distribution of rainstorm in Guizhou. |
