Session 14B Numerical and Observational Studies: Microscale and Mesoscale Processes over Complex Terrain

Thursday, 16 January 2020: 3:30 PM-5:00 PM
258B (Boston Convention and Exhibition Center)
Host: 30th Conference on Weather Analysis and Forecasting (WAF)/26th Conference on Numerical Weather Prediction (NWP)
Bruce Telfeyan, 557 Weather Wing, Offutt AFB, NE; Heather A. Holmes, University of Nevada, Reno, Atmospheric Sciences Program, Reno, NV and Holly J. Oldroyd, Univ. of California, Davis, Civil and Environmental Engineering, Davis, CA

Atmospheric processes occurring over complex terrain pose many challenges for hydrological and meteorological prediction.  These processes are 3-D, multi-scale, and affected by terrain slope, heterogeneous surface roughness, and other land-cover characteristics.  Understanding the physics associated with these processes is critical to predicting a large number of geophysical phenomena (e.g., the timing of snow melt and runoff, glacier-mass balance and retreat, fire weather, etc.).
