| 摘 要： | 用ＰＳＵ／ＮＣＡＲ中尺度数值模式，对１９９５年６月２３至２４日的一次大暴雨过程进行了模拟试验．结果表明，潜热的反馈及地形的强迫对降雨量起决定性的作用，潜热对降雨量的增幅达８０％，地形为６８％，其中盆地北侧山脉起绝大部分的作用，盆地南侧的武夷山、仙霞岭对金衢盆地降水量的影响很小，而对其东面洞宫山脉一带的雨量有很大的影响．

| Abstract: | Using NCAR/PSU meso scale model,a numerical simulation has been conducted for a heavy rain case occurring during June 23 24,1995.The results show that latent heating and orographic forcing have the most significant effect on rainfall.The latent heating and orographic increments of rainfall account for nearly 80% and 68% of the totals respectively.The northern mountain range in the basin has a more crucial forcing effect on rainfall in this case than the southern range.However,the southern mountain range has a notable influence on rainfall in the Dong Gong mountain area in eastern Zhejiang. |
