A method of acting on convective clouds is disclosed which comprises the steps of determining the development stage of a cloud and its direction of movement, selecting action zones therein and forming descending air flows or introducing a crystallizing reagent into said action zones. The action zones are chosen to be at the front and back parts of the cloud, two points then being selected which are situated on opposite sides of the point of deceleration of the tangential component of cloud rotation as viewed from the front and back parts, respectively, at a distance of 1 to 10 km from the first visible side boundary of the cloud, and the point of maximum value of the tangential component of cloud rotation and at a distance of 1 to 10 km from the second visible side boundary of the cloud, ascending or descending air flows being formed simultaneously or successively in two, three or four of said action zones. |
