This certainly applies to the precipitation falling near 0°C (including freezing rain, ice pellets and wet snow) but there is still considerable uncertainty regarding its characteristics, formation, detection and simulation. This limits our monitoring efforts as well as our predictive capability at all time scales. Such issues will be reviewed in this presentation.
