| 摘 要： | 在山区可能最大降水研究中,关键是如何估算地形对暴雨的影响.本文首次提出一种定量估算地形对暴雨影响的方法.该法基于天气-气候分析和实测降雨的统计分析,利用二维差分近似估算出特定流域地形对暴雨影响的大小及其时、空变化过程.通过海南岛昌化江流域山地PMP估算的实例,发现地形对暴雨影响的大小及其空间分布是随着历时而变化的.应用此法不仅能估算出山岳区的PMP数值,而且能绘出符合成因分析的PMP等雨量线的时、空变化情况.本文还结合实例分析,指出了"分时段地形增强因子法"在暴雨移置研究中的应用前景.

| Abstract: | For the study of Probable Maximum Precipitation in orographic region the key but more difficult point is how to estimate the effects of topography on storm rainfall. The Step-Duration Orographic Intensification Factors Method is based on the synop-climatic analysis as well as the statistical analysis of observed rainfall data in situ. The method offers a possibility to quantitatively estimate the synthetic influence of a particular basin terrain on rainfall and its variations both in space and time by means of a two-dimensional discrete scheme. The philosophy of the method with a practical application is presented in more detail. |
