Atmospheric models in the numerical simulation system (SPEEDI-MP) for environmental studies

Nagai, Haruyasu ; Terada, Hiroaki

As a nuclear emergency response system, SPEEDI and WSPEEDI were developed to predict the atmospheric dispersion of radionuclides. Recently, a numerical simulation system SPEEDI-MP has been constructed to apply for various environmental studies. SPEEDI-MP consists of models for the atmospheric, terrestrial, and oceanic environments, database for model inputs, and system utilities. New WSPEEDI in SPEEDI-MP consists of the atmospheric dynamic model and particle dispersion model and has high performance for diffusion and deposition calculations. It simulated successfully the dispersion of $^{137}$ Cs released by the Chernobyl accident.
