A Doppler Sodar Case Study of Top-Down Convection and Convective Dissipation of Stratus

Stratus dissipation over the Swiss Plateau has long been a forecasting problem. A case study of stratus structure and development was conducted during the winter of 1997-98. Measurements were performed with the monostatic Doppler sodar of the Swiss Federal Institute of Technology, Zurich, to supplem...

Summary:Stratus dissipation over the Swiss Plateau has long been a forecasting problem. A case study of stratus structure and development was conducted during the winter of 1997-98. Measurements were performed with the monostatic Doppler sodar of the Swiss Federal Institute of Technology, Zurich, to supplement conventional observation methods. The results show that sodar measurements can supplement other observation methods in a useful way, especially when the data analysis of echo patterns and high-resolution vertical velocities are combined.
