What is it about?
This is a study of severe wind events in the western foothills of the southern Appalachian mountains which produced extremely high winds (80-95 knots or 90-110 mph) and strong warming in a narrow area. A long-term study was also conducted to determine the frequency and typical timing of these winds.

Why is it important?
Strong southeasterly (or southerly) winds producing severe damage occur every year in the foothills of the southern Appalachian mountains due to mountain waves. Some mountain wave events have produced extremely high winds (80-95 knots or 90-110 mph) which caused significant damage within the Great Smoky Mountain National Park and Camp Creek community of east Tennessee. Strong warming has also been observed with these type of winds, which typically caught forecasters by surprise. This study examines why these wind events occurred, and examines the typical characteristics of these wind events.
