Case Study 009"Severe Icing
Event"
6 March 1996
Case Summary
Conditions conducive to aircraft icing occur across much of the United States during the winter months. These conditions are often the result of several synoptic-scale processes that include the large-scale flow, moisture, temperature and vertical motion regimes. Icing conditions are also closely tied to mesoscale and microscale interactions such as cloud liquid water content and distribution, cloud glaciation, precipitation and supercooled large drop (SLD) formation processes. During March 6, 1996 several of these large and smaller scale processes combined to produce a large area of significant icing conditions which included portions of the Mid-West to Northeast and the Northwest.
