Abstract: With a view to gaining insight into the role of differential friction in the movement of tropical cyclones, an analytical solution of the barotropic vorticity equation which included a frictionally induced vertical velocity ...

Abstract: A diagnostic numerical model was developed for calculating air motion in the atmospheric boundary layer near a front in terms of certain local parameters; namely, the geostrophic wind in the warm air, the densities of the ...

Abstract: A primitive equation model was utilized to describe the initial fields of atmospheric motion, temperature and humidity for the case of a snow-squall situation over Lake Ontario. Of primary interest in this study is the ...

Abstract: This study clarifies the dependence of frontogenesis on vertical and horizontal motion, baroclinicity and the liberated latent heat of vaporization. In a typical case, the relative contributions of the horizontal and ...

Abstract: The possible roles of the boundary flux of potential energy and the basic tropical easterly current in maintaining weak, quasi-steady, linear, lower tropospheric disturbances were examined for several map times utilizing ...

Abstract: Under elementary considerations the vorticity changes induced by differential friction and asymmetry of the combined hurricane and large-scale flows were incorporated in the prediction equation and integrated with a view ...

Abstract: A two-layer discrete vortex model developed previously is applied to the study of short-term displacements of tropical vortexes due to their mutual interaction. The model treats the tropical cells as point-form vortexes ...

Abstract: A vigorous winter storm over North America is studied by means of an eight-level primitive-equation model. Included are orography, surface and internal friction, long-wave radiation from clouds and water vapor, large-scale ...

Abstract: Organization of convection into bands over the Arabian Sea during a monsoon onset was studied analytically. Observed vertical profiles of temperature, moisture, and wind velocity were used as base states by a linear model ...

Abstract: A study of the effect of mesoscale latent heat release on synoptic-scale mid-tropospheric warming was made by employing a 10-level diagnostic model and the special data gathered by the National Severe Storms Laboratory. ...
