LOLEPSHIN, the New, Dynamic, Glaciogenic Seeding Optimized by Self-enhancing Feedbacks

Development of an effective seeding method is a key to solve many problems of weather modification and their evaluation.  Based on scientific knowledge in theory, experiments and field tests of varying scale, a glaciogenic seeding method was formulated by making optimal use of the phase change energy of growing seeded crystals, the resultant buoyant air motion and the generated eddy field of turbulent diffusion to feedback the supercooled clouds to the crystals for sustained growth and energy generation. The method is called LOLEPSHIN (Low Level Penetration Seeding of Homogeneous Ice Nucleant) and has two basic processes, RETHIT (Roll-up Expansion of Twin Horizontal Ice Thermals) and FILAS (Falling-growth Induced Lateral Air Spreading).  Recent seeding tests showed marked, large, and often predictable results in reaction time and precipitation area, followed by clearly recognizable secondary effects such as new cloud condensation in the increased updraft and enhancement of cloud and precipitation activities due to lifting of the air surrounding the induced downdraft of melted seeded precipitation.  The seeding reactions variously observed and the new horizon of the application will be shown.
