Effect Assessment of a Simulation Test of Airplane Rain Enhancement with Area Control

By using of a simulation test with a non-randomize area control,the effect assessment of airplane rain enhancement over Zheling Reservoir of Jiangxi province from 1979 to 1982 was conducted and compared with other non-randomize tests.It is shown that the area control test is an objective assessment method better than others.Mean rain enhancement of every airplane operation is 1.37mm per four hours,and the relative rate of rain enhancement is 24.92%.By comparing accuracy of every method,the false effect of area control test is 0.53%,but the falso effect of sequence test,area contrast test and historical regression test is 9.89%,-19.52% and 19.58% respectively.
