Measurement of Upper Convective Boundary Layer Parameters by Means of LIDAR.
Abstract
Data obtained over Madison, Wisconsin, over a three year period from 1975 to 1977 primarily during the spring, summer and fall are presented. Aspect ratios of convective cells were measured using lidar RHI scans vary from .5 to 1.5. Lidar measurements of circulation patterns around convective cells show that the strongest rising motion occurs on the upwind side of the circulation pattern while compensating sinking motion occurs on the downwind side. These observations also confirm the importance of the inversion height as a length scale in convective situations. Turbulent velocity measurements combined with lidar measurements of the inversion height were used to calculate the energy dissipation. The results agreed with local tower measurements.
