Projection onto Ground Rainfall Distributions of Effects of Seeding Convective Cloudcells
AbstractObserved changes in the ground distributions of rainfall in the first and Second Israeli cloud seeding experiments are related to observed changes in cloud cell size and rainwater volume, rate and duration. The ground information is recorded by standard stations under static seeding experimentation in Israel, while the cloud information is of a radar records under dynamic seeding experimentation in Florida. The increase in the ground rainfall intensity seems to follow the increase in cloud cell depth. The increase in the ground rainfall duration, frequency and spatial correlation is suggested to be related to the increase in the cloud size and rainwater content, and to the kinematics of its motion. The well known increase in the ground rainfall depth (Gagin and Neumann, 1974).
