摘要

An investigation is made into the hail production characteristics of a supercell-type storm that occurred in Central Oklahoma on 29 May 1976. The main research tool employed is a three dimensional numerical hail growth model with the flow field being taken directly from a triple Doppler synthesis. The Doppler data set from this storm is not ideal in that velocities are missing from one or more radars at both the lowest and highest storm levels. In addition, the storm is not geographically well situated with respect to the radars for a triple Doppler synthesis. The hail growth model reveals that embryos which experience significant growth can originate from various locales. Typically, any embryo that enters an updraft will experience some growth. Results of the model have implications for the three seeding techniques of artificial hail suppression.
