Impacts of terminal velocity on precipitation prediction and the error representation of terminal velocity in ensemble forecasts [PDF]

open access: yesAtmospheric Science Letters, 2020
Impacts of terminal velocities (rainwater, snow, and hail) on precipitation and the representation of terminal velocity uncertainty in ensemble forecasts were discussed in several idealized scenarios differing in intercept parameters and environmental ...
