Abstract: The height and temperature of first radar echoes observed on 49 test cases in a randomized cloud seeding project have been related to seeding treatment and to five cloud parameters, namely, cloud base height, cloud base ...

Abstract: A 3-year randomized crossover seeding experiment has been conducted in South Dakota to test effects of artificial nucleation upon supercooled convective clouds of spring and early summer. The associated rainfall observations ...

Abstract: An extensive observational program has resulted in a description of the typical hailstorm of western South Dakota. The typical storm is cellular with new cells developing on its southwest side. The median hailstorm produces ...

Abstract: Magnetic tape records for radar observations of 80 moving one-hour test cases in a three-way randomized (no-seed, salt, silver iodide) cloud seeding experiment have been analyzed in terms of echoing areas and radar-estimated ...
