Session: Analysis and Forecasting of Mesoscale Weather Phenomena - II (100th American Meteorological Society Annual Meeting)

Wednesday, 15 January 2020: 3:00 PM-4:00 PM

151A (Boston Convention and Exhibition Center)

Host: 30th Conference on Weather Analysis and Forecasting (WAF)/26th Conference on Numerical Weather Prediction (NWP)

Chair:

This session will be hosted by the 30th Conference on Weather Analysis and Forecasting (30WAF). We welcome abstracts on phenomena including (but not limited to) snow-banding, drylines and associated circulations, bores, density currents, etc. -- as well as their upscale influence on the larger environment.
