Comparisons of the time-averaged vertical velocity observations from the Platteville, CO, MST radar with synoptic-scale vertical velocities computed by the adiabatic and quasi-geostrophic equation methods are made for several case studies. These first results show that an MST radar can detect synoptic-scale vertical velocities and that at Platteville the most favorable comparision occurs when the synoptic-scale vertical velocity is large and the temporal variance of the MST radar data is small.
