Abstract: A grid-point method for integrating the shallow water equations based on a split semi-Lagrangian treatment of advection and an Eulerian alternating direction implicit treatment of the adjustment terms is presented. The ...

Abstract: The CISK theory is generalized by incorporating an explicit solution of the time-dependent boundary layer equations for the case of exponential growth and allowing the interior flow to be unbalanced. Two separate modes of ...

Abstract: A series of 10-day forecast experiments has been carried out to investigate the sensitivity of a global semi-Lagrangian model to the value of the uncentering parameter ?, the magnitude of the time step for the dynamics, ...

Abstract: Two parallel 5-year climate simulations have been carried out to assess the effect of changing from an Eulerian to a semi-Lagrangian formulation of a general circulation model's dynamical core with the physical parameterizations ...

Abstract: The stability properties of some simple semi-Lagrangian advective schemes, based on a multiply-upstream interpolation, are examined. In these schemes, the interpolation points are chosen to surround the departure points ...

Abstract: A method for improving the estimate of the departure point position in a two-time level semi-Lagrangian integration scheme is introduced. It involves ?centering in space and time? to arrive at the best value of the advecting ...

Abstract: A stable, semi-Lagrangian, semi-implicit, two-time-level, gridpoint integration scheme for the shallow water equations on the sphere is presented. A rotated spherical coordinate system is used to integrate the equations ...

Abstract: An adiabatic global multilevel primitive equation model using a two time-level, semi-Lagrangian semi-implicit finite-difference integration scheme is presented. A Lorenz grid is used for the vertical discretization and a ...

Abstract: The Arakawa-Schubert (1974) convective parameterization scheme is applied to a quasi-geostrophic CISK model with continuous vertical resolution. Considering only the effects of non-entraining clouds and assuming that the ...
