Abstract
Using parameterizations of cloud microphysics, a technique to forecast supercooled cloud events is suggested. This technique can be coupled on the mesoscale with a prognostic equation for cloud water to improve aircraft icing forecasts. The procedure is validated using comparisons with airborne measurements from the Canadian Atlantic Storms Program. As an illustration of the application of this forecast technique, constant-pressure maps showing regions of cloud ice, supercooled cloud water, and cloud liquid water are presented for two particular cases.
