Application of Cumulus Model to Artificial Precipitation Enhancement

Cumulus precipitation days (R≥0.1mm) in Fuzhou, Fujian during summer and autumn drought seasons from 1985 to 1994, were classified to twelve weather patterns, and were simulated respectively by and 1-D time dependent dual-paremeter cumulonimbus cloud model. The precipitation forecast accuracy is more than 75 percent. By artificial seeding simulation, the physical character of cumulus precipitation during drought season in Fujian, the artificial seeding method, the seeding dose and seeding position were determined, Some significant results were achieved. Using NDP FORTRAN and BORLAND C++ program design the cumulus model systems were applied to the system of command of artificial precipitation enhancement.
