Abstract:
The physical effects assessment provides physical basis for the artificial precipitation test, so it has got more and more attentions. Based on the aircraft operations information in Zhangjiakou on May 1, 2009, this paper tries to find the contrast area from different heights to conduct the physical examination of the operational effects. The results show that: Making use of reduction to absurdity, the FSSP (range one) measurements of droplets are found to be dominated by ice phase and liquid phase when it is -10℃, and the rapidly growing moment of concentration of the particles is relatively consistent with the rapidly growing of the ice phase cloud particles. The actual results of observation are basically in agreement with cold cloud catalytic principle, and the enlargement of rainfall area has proved that this aircraft cloud seeding is effective to a certain extent.
