Observational Evaluation of Snow Cover Effects on the Generation and Modification of Mesoscale Circulations

This thesis presents results from an observational evaluation of the impacts of snow cover on mesoscale flow due to the relatively small thermal forcing of snow cover. Specifically, the suppression of daytime upslope flow due to the presence of widespread snow cover, and the generation of thermally-...

Description
Summary:This thesis presents results from an observational evaluation of the impacts of snow cover on mesoscale flow due to the relatively small thermal forcing of snow cover. Specifically, the suppression of daytime upslope flow due to the presence of widespread snow cover, and the generation of thermally-direct mesoscale circulations caused by variable snow cover are examined. Thermally direct circulations caused by variable snow cover are examined in some detail through aircraft observations. Four case study presentations from the results of an aircraft field experiment are shown. Keywords: Air flow stabilization; Lower atmosphere; Pressure gradients; Upslope flow suppression; Snow breeze effects; Atmospheric circulation; Theses.
