The Possibility of Numerical Nowcasting of Storms

Since L. F. Richardson introduced the concept of numerical weather prediction in 1922, it has become an important part of meteorological services. The operational nurnerical weather prediction of large-scale atmospheric circulation systems has a 30-year history, but precipitation forecasting and nowcasting of meso-scale severe weather remain in its experimental stage, and the advance of their numerical predictions is slow. Theoretical studies indicate that the predictability time lhnit of the convective storm-scale system has
