摘　　要：依据实时探测的温度、露点温度、液态水含量等要素及计算"冰水转化"区,从而判断增雨作业区域,确定催化时机、部位和催化剂种类。结果表明,当"冰水转化"区大于零且液态水含量大于等于0.5 g/m3时,条件①温度小于等于-8℃且大于等于-24℃时,开始播撒碘化银烟条;条件②温度小于0℃且大于-8℃时,开始播撒液体二氧化碳试剂。机上探测设备的应用,较好地提高了增雨作业的科学性,解决了机上催化剂选择、播撒区域、时机确定等问题。同时,利用雷达探测资料,对催化区和非催化区、催化前和催化后的雷达最大反射率进行了对比,分析得出催化区雷达最大反射率强度明显增强,因而从物理检验的角度证明了人工增雨机上催化剂播撒决策系统指挥有效。Based on the air factors, such as the temperature, dew point, liquid water content and calculating the area of e-Ei, the area of increasing the rain task, catalyzing opportunity and region, the kinds of catalyst is decided. When the conditions of the area of e-Ei 〉0 and LWC ：〉0.5 g/m^3 are sarisfled, one condition of the temperature（ -24 ℃ T≤ -8 ℃） is tenable, AgI catalyst is seeded. Another condition of the temperature（ -8℃ T≤0 ℃） is tenable, the catalyst of liquid CO2 is seeded. Some main cloud seeding parameter indexes of precipitation enhancement are provided to operators. Then the operators decide that the seeding catalyst is seeded whether or not. The seeding effect is improved. The seeding occasion is solved. At the same time, on the basis of radar probing data, the radar echo is greatly swelled in seeding area but the radar echo is not changed in non-seeding area or before seeding area.
