The loss of AgI aerosols in clouds during weather modification operation

In this paper,the loss of AgI aerosols in the operative clouds has been calculated,it shows that the wash-out by rain is not neglectful. Therefore it is most important to increase the throwing height of the anticraft gun shells and to locate the AgI aerosols into the upwind regions of the clouds in sense of precipitation enhancement or hail suppression.
