Scientific Evaluation and Assessment of ASL Developed Moist Atmosphere Models for Low Stratus Subclouds

Abstract

The problem is to describe the thermodynamics and haze microphysics of the subcloud layer. This is extremely difficult if the cloud is low and the lower boundary of the subcloud layer is the ground like in the present case. In such a case an adequate description of the turbulent processes in the subcloud layer is necessary to get reliable results. The related problems are difficult because the condensation processes have a considerable influence on turbulence. Comparison of measured and computed liquid water profiles in the subcloud layer fields that there should be an agreement between present theory and reality within a factor of about 3. Considering the errors of measurement and the above mentioned suggestions this agreement is valued to be very good and promising. Further steps of improvements os the model and its final version should be checked by well designed experiments.
