Use of cloud observations and mesoscale meteorology models to evaluate and improve cloud parameterizations. Technical progress report, 1 October 1992--30 September 1993
This research program utilizes satellite and surface-derived cloud observations together with standard meteorological measurements to evaluate and improve our ability to accurately diagnose cloud coverage. Results of this research will be used to compliment existing or future parameterizations of cloud effects in general circulation models, since nearly all cloud parameterizations must specify a fractional area of cloud coverage when calculating radiative or dynamic cloud effects, and current parameterizations rely on rather crude cloud cover estimates. During the first phase of this research program, our goal is to evaluate and improve the methods for calculating cloud cover within a mesoscale meteorology model. To accomplish this, a mesoscale meteorology model will be quantitatively evaluated using available cloud cover databases, including the US Air Force 3DNEPH and RTNEPH satellite-derived cloud fields, as well as CART data as they become available. During the second phase of this research, the cloud cover data and improved parameterizations of cloud coverage developed during the first phase will be incorporated into a mesoscale meteorology model. Model forecasts which utilize the observed cloud coverage and depth should be improved relative to forecasts which crudely specify cloud properties.
