摘　　要：在开发云水资源中,火箭人工增雨作业起到非常重要的作用。本文针对WR型人工增雨火箭,以播云碘化银浓度大于10L-1的扩散体所移过的累积面积在地面上的投影为有效播云区。利用湍流扩散方程,对湍流扩散系数、风速和作业仰角进行敏感性试验。结果表明:湍流扩散系数与最大扩散半径成正比,与达到最大扩散半径的时间成反比,有效播云区面积与环境风大小成正比。在迎风多轮火箭作业中,根据仰角不同,每轮发射三发火箭弹,发射夹角在32°—90°之间变化。在不同风速下,当仰角在64°-52°、湍流扩散系数在20-100m2.s-1之间时,三发火箭弹的有效播云区面积最大。Rocket precipitation enhancement in the development cloud water resources plays a very important role.For WR-type Precipitation enhancement rockets,we named the cumulative area of ground projection that AgI diffusion concentrations is greater than 10L-1 as the effective cloud seeding area.Using of turbulent diffusion equation,we performed a sensitivity test of the turbulent diffusion coefficient,wind speed and operation elevation angle.The results showed that: the turbulent diffusion coefficient is proportional to the diffusion radius,and it is inversely proportional to the time of maximum diffusion radius;the effective cloud seeding area is proportional to the winds.In the multiple rounds and windward operation,according to difference of elevation angle,each round fires three rockets,launching angle between two rockets is 32-90 degrees.In different wind speeds,when at 64°-52°elevation,turbulent diffusion coefficient in 20-100m2·s-1,the effective cloud seeding area of three rockets is the biggest.
