Case soundings

ANC Soundings from the nearest 12-hour increment PRIOR to the high wind report. These four soundings are from some of the strongest events, and include well defined specific features favorable for windstorms. These features include:

• Strong low level southeasterly winds
• Winds veering with height, becoming southwesterly in the mid levels
• Conditionally unstable mixed boundary layer
• Mid level temperature inversion or stable layer
• Conditionally unstable layer above the inversion

Future ideas: Create composite soundings for strong versus weak classes. Compare these specific features in the composites.
