摘要: |
从第二类有限区域湿有效能量收支方程出发,计算方程主要几项的数值,分析广东省三次暴雨的能量积聚和释放。结果表明:暴雨区及其临近地区在暴雨过程之前、暴雨中期和暴雨之后,不但各项的数值有很大差异,而且各项所起的作用也明显不同。 |

Abstract: |
Using a new formula of moist available energy(MAE),a number of key terms of MAE from three cases of heavy rain in Guangdong province in 1998 were calculated,and energy accumulation and discharge were analyzed.The main results show that there are clear differences not only in the number of key terms in the formula but also in the function of each term in the area of heavy rain during different precipitation periods. |
Key words: energy accumulation energy discharge heavy rain |
