The Application of Pole Orbit Meteorological Satellite Data to the Evaluation of the Effect of Artificial Stimulation of Precipitation by Airplane on 14 March, 2000

摘要

During the course of weather modification by airplane on March 14, 2000, the polar orbit meteorological satellite real time remote sensing offer us some proof for artificial stimulation of precipitation. We analyze the truth of catalyst diffusion after the airplane flying and discuss the wind transportation for catalyst, the effect of artificial stimulation of precipitation on the ground. The preliminary result : (1), After the course about 1 hour 23 minutes, the maximum random movement diffusion width is 11km, the catalyst's random movement diffusion area is about 2505km~2, and there has a sunk area about 1505 km~3 on the top of the cloud. (2), According to the analysis of satellite data ,the effected area by wind transportation is about 7500 km~2, it is 3 times to the random movement diffusion area. And this is the key factor of catalyst diffusion.
