Abstract: A simple analytical expression for indexing the orographic precipitation rate over high mountains is presented. The formula is based upon the assumption that the moisture convergence in the mountainous boundary layer ...

Abstract: A simple method is developed for computing the interactions among various factors influencing the atmospheric circulations. It is shown how numerical simulations can be utilized to obtain the pure contribution of any factor ...

Abstract: In contrast to earlier studies, where only binary tropical storms were explored, the rotation at midlatitude and the subtropics is studied here. The point vortex theory applied to two neighboring cyclonic vortices isolated ...

Abstract: A two-dimensional mesometerological model was originally constructed by Alpert et a.. to simulate the summer air circulation in the area between the eastern Mediterranean waters and the Golan Heights involving en route ...

Abstract: A deep polar air-mass penetration to the eastern Mediterranean in November 1982 is described. The unusual weather and, in particular, the rain pattern is discussed. This event contributes to heavy rain in the inland stations, ...

Abstract: In a first theoretical study, the reasons for anti-clockwise rotation (clockwise rotation in the Southern Hemisphere) of the wind hodograph in the boundary layer are investigated. As observations of wind hodographs show ...

Abstract: A one-level sigma-coordinate model originally developed by Danard and modified by Mass and Dempsey and Alpert et al., is applied to the study of surface flow over an averaged summer diurnal cycle in Israel. The detailed ...

Abstract: The diurnal and interdiural wind variabilities are defined in terms of the ?relative gustiness? ?σ?/V?. The proportion α between the diurnal and the interdiurnal variabilities thus defined is suggested as a useful index ...

Abstract: A four-dimensional computer-analysis program for visualizing atmospheric fields on a personal computer is presented. The Program can display, on screen, a fast-time animation of meteorological fields on various surfaces ...
