Abstract: The response of a linearized numerical model of African waves to changes in the specification of the zonally-averaged flow is investigated. The growth rate and wavelength of the most unstable mode are found to depend on ...

Abstract: The U.S. Navy?s operational implementation of the hurricane prediction system developed at the National Oceanographic and Atmospheric Administration?s Geophysical Fluid Dynamics Laboratory is described, and the performance ...

Abstract: The linear stability of two coupled shallow water models of the equatorial atmosphere and ocean is investigated analytically. The ocean-to-atmosphere coupling is parameterized in terms of the sea surface temperature ...

Abstract: The growth of synoptic scale cyclones imbedded in a baroclinically unstable zonal flow over a long straight mountain range is investigated. Two different analytical models of the phenomenon are used. The first model uses ...

Abstract: The effect of topography on the evolution of a disturbance in a baroclinically unstable mean flow is studied using a three-dimensional primitive equation model. A procedure is developed to compare control integrations with ...
