Numerical Simulation of the Life History of a Hailstorm

摘要: Abstract A two-dimensional, time-dependent cloud model has been used to simulate the evolution of hail cells and hailstorms. The under development for several years tested on a few days real data, gives reasonable predictions convective characteristics essential precipitation processes both severe nonsevere convection days. Hydrodynamic equations for. deep are integrated over 20 km square grid with 200 m spacing between points. Cloud formation employing bulk water techniques simulated in model.
