| 摘 要： | 应用对流云数值模式模拟了2001年7～9月湖南省三个探空站0000和1200(世界时)462个对流云降水算例.模拟结果表明(1)其中53天的198个算例属于有利人工增雨的天气形势,133个算例的可播度大于零,54个算例的增雨率大于零;(2)7～9月天气形势有利于人工增雨日的算例,对流云平均含水量为575万吨,平均降水效率11.4%;(3)8月降水潜力大于7月,9月降水潜力最小.这表明即使大旱的2001年湖南省夏秋季对流云仍然有一定的增雨潜力.

| Abstract: | Simulation is conducted on 462 examples of convective cloud precipitation with the radiosonde data from three radiosonde stations in Hunan Province at 00: 00 and 12:00 UCT during July, August and September in 2001. The results indicate: (1) There are 198 examples in 53 days belong to favorable weather pattern, 133 examples with the potential seedability index being more than zero, and 54 examples with the rate of rain enhancement being more than zero. (2) The cases in which the average water content of convective clouds is 5750 kiloton and the average precipitation efficiency is 11.4% are favorable for rain enhancement. (3) The precipitation potential is greater in August than that in July and the least in September. Even though severe drought occurred in July, August and September in 2001, the rain enhancement is also possible. |
