A33Q:
Observations and Predictability of the Atmosphere over Complex Terrain I


Session ID#: 10923

Session Description:
Mountainous terrain is complex given the variety of slope angles and orientations, surface types, valley widths and curvatures. Atmospheric circulations over this intricate geometry arise from synoptic and/or thermally-driven pressure gradients, resulting in inherently complex motions with a wide range of spatial and temporal scales. Although recent years have seen sustained efforts to improve the predictability of flows over complex terrain, several scientific questions remain unsolved.

This session focuses on microscale and mesoscale atmospheric phenomena taking place in the atmospheric boundary layer over mountainous terrain. We seek original contributions spanning from theoretical, observational and modeling studies that are related to mountain meteorology. Topics of interest emerging from synergetic fields are also welcomed, including data assimilation, wind energy, hydrology, air quality, fog formation, fire weather, and snow transport.
