Abstract : The processes taking place in the atmospheric desert planetary boundary layer determine the evolution of those circulations which control not only its subsequent behavior, but that of the atmospheric layers above it. The structure of the boundary layer at any given time determines the subsequent low level stratification, and hence the occurrence of such phenomena as radar ducting, dust/sand storms, low level jets. The general objective of the proposed research is to develop, refine, and integrate a numerical model of the planetary boundary layer which will have the capability of predicting its future behavior. The model will be tested with reference to an observational mesonet which will be established in the Negev desert. A feature of the model will be the ability to assess the effect on a mass of warm dry air from the land passing over a body of water. Another related feature of the model will be its ability to predict the variation in desert inversion height - a parameter of utmost importance in controlling desert circulation. The same model will also be applicable in prediction of the behavior of the marine inversion. By including a dust concentration equation the capability of the model will be increased to predict this very important desert parameter.
