MID-TROPOSPHERIC DRY LAYERS AND THEIR RELATIONSHIP TO PRECIPITATION TYPE IN A SUB-FREEZING TROPOSPHERE
The effect of mid-tropospheric dry layers on precipitation type is examinedfor cases in which freezing (vs.frozen) precipi-tation fell when the entire depth of the troposphere was well below freezing. Aggressive mid-level dry slotting associated with a mature cyclone is examined. The depth of the mi...
