| 摘 要： | 利用新给出的湿有效能量的表达式计算了１９９１年５～７月亚洲地区逐日的湿有效能量。结果表明：（１）亚洲地区的湿有效能量变化特点能很好地揭示该地区春向夏的季节转变；（２）江淮地区人梅前后湿有效能量有显著差异，入梅前该地区湿有效能量低，梅雨期湿有效能量高；（３）１９９１年江淮地区３段持续性暴雨在湿有效能量上有明显反映，暴雨发生在江淮地区大气对总湿有效能量贡献大的时段。

| 关 键 词： | 湿有效能量 梅雨 暴雨 |

| Abstract: | Used a formula developed by auther, the daily moist available energy in East Asia iscomputed from May to July in 1991. The evolution characteristics of the moist available energy and its relation with the three rainy intervals are briefly studied. The main results areas follow: 1) The evolution characteristics of the moist available energy in the East Asia canreveal the season change from spring to summer. 2) The evolution of moist available energyover the Yangtze-Huaihe River oscillated obviously, the moist available energy is low in thepre-maiyu period but high during the maiyu preiod. 3) There are three periods of torrentialrain which correspond with the peaks of the moist available energy over the Yangtze-HuaiheRiver. |
