WebHAILCAST is designed to be embedded within a convective-allowing forecast model. It will produce forecasts of hail size, and if desired, hail density and terminal velocity. Hailstone growth through liquid water accretion, ice particle collection, condensation, and sublimation Explicit calculation of hailstone temperature WebJan 7, 2024 · In particular, hail sizes are maximized for intermediate CAPE values in the range we examined. Results show a non-monotonic relationship between the hailstones’ residence time and CAPE due to changes to the updraft wind field. The ratio of updraft area to southerly wind speed within the updraft serves as a proxy for residence time.
