Dynamics of the Marine Cloud Layers.

Abstract

Goals of this research have been to identify physical processes that determine the dynamics of marine cloud layers and to quantify roles of turbulence, convection and thermal radiation that play in formation. dissipation and stability of the marine cloud layers. And immediate objectives of the research are to advance turbulence models, use efficient numerical schemes, develop computer simulation programs, simulate the marine cloud layers and compare computer results with published experimental data on the marine cloud layers so as to yield insights into the cloud's physical processes. For these objectives, two theoretical models. using the second order turbulence closure and the large-eddy simulation (LES), respectively, have been developed. In addition. a hybrid model has been presented. It uses a framework of multidimensional LES model but uses turbulence intensity values calculated by unidimensional second order closure turbulence equations. Results of the computer simulation are compared with experimental data retrieved from reliable web-site sources.
