Abstract: A method was recently proposed for evaluating the impact of a perturbation, such as air pollution or urbanization, on the precipitation at a location by calculating the ratio between the precipitation at the perturbed ...

Abstract: Nonlinear, dispersive perturbations are applied to a single layer, geostrophic, density current of zero potential vorticity, which flows along a vertical wall (coast) and is bounded by a free streamline in the seaward ...

Abstract: The linear instability of circular quasigeostrophic vortices with horizontal cross sections of angular velocity identical to those that fit the observations of submesoscale eddies in the ocean is investigated analytically ...

Abstract: Two relatively simple physical oceanographic processes are suggested as plausible explanations for the biblical description of the Israelites' Crossing of the Red Sea during their exodus from Egypt. The first involves ...

Abstract: It is shown that tidal perturbations of a geopotential height in an inviscid, barotropic atmosphere can turn a purely inertial, predictable trajectory of a Lagrangian particle chaotic. Hamiltonian formulation of both the ...

Abstract: A Lagrangian model is employed to study the characteristics of a horizontal cross-equatorial flow. The Coriolis force and the mean meridional pressure field assumed here render the dynamics of particle flow across the ...

Abstract: The interaction between a simple meandering jet such as the Gulf Stream, and an eddy is shown to greatly enhance the mixing and dispersal of fluid parcels in the jet. This enhanced mixing is quantified by calculating the ...

Abstract: Solutions of an axially symmetric inviscid shallow-water model (SWM) on the earth forced by equinoctial differential heating are constructed using numerical integration of the time-dependent equations and analysis of their ...

Abstract: The linear instability of a zonal geostrophic jet with a cosh?2 meridional profile on an f plane is investigated in a reduced-gravity, shallow-water model. The stability theory developed here extends classic quasigeostrophic ...

Abstract: An axially symmetric inviscid shallow-water model (SWM) on the rotating Earth forced by off-equatorial steady differential heating is employed to characterize the main features of the upper branch of an ideal Hadley ...
