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.en-USAll UHM dissertations and theses are protected by copyright.
