Satellite Analyses of Antarctic Katabatic Wind Behavior

摘要: Abstract Prominent warm signatures of strong, negatively buoyant, katabatic airstreams are present at thermal infrared wavelengths as a result intense vertical mixing and drift-snow transport within stable boundary layers. These tracers used to illustrate several aspects the behavior winds in Ross Sea sector Antarctic. The satellite features compared with surface-based observations whenever possible. Converging surface-wind upslope from Terra Nova Bay shown closely follow observed time-averaged streamlines drainage airflow. satellite-observed core airstream descends sea level via direct route, but complex three-dimensional trajectories manifested marginal regions. Katabatic propagating horizontally for hundreds kilometers over southwestern do not exhibit expected influence Coriolis force. be climatological Ice Shelf which ...
