A numerical study of the effect of cloud nuclei on the initiation of rain from warm clouds

The effects of the cloud nucleus size distribution and number concentration on rain initiation from shallow maritime warm clouds are examined in a one-dimensional, time-dependent cylindrical cloud model. Calculations include nucleation, condensation on both nuclei and drops, collection of drops and scavenging of nucleus-size particles to drops. It was found that nuclei of mass about 10^-15 g are most efficient for warm rain development and the number concentration normally observed near Hawaii is the optimum concentration for maximum rainfall.
