Abstract: The problem of genesis of easterly African waves is reexamined as a linear eigenvalue instability problem of a supposedly realistic basic zonal shear flow with and without a cumulus heating. Evidence will be presented to ...

Abstract: It is hypothesized that few African waves become tropical storms because they typically have an unfavorable thermal structure that cannot be sufficiently transformed during its propagation across the Atlantic Ocean by the ...

Abstract: This paper investigate the equilibration of finite amplitude waves in a forced, dissipative, high resolution, barotropic beta-plane model. The external forcing is prescribed in the form of an easterly Bickley jet and the ...

Abstract: Using large-scale analyses, the effect of tropical cyclone?trough interaction on tropical cyclone (TC) intensity change is readdressed by studying the evolution of upper-level eddy flux convergence (EFC) of angular momentum ...

Abstract: In this paper, nonlinear evolution and equilibration of the barotropic waves in a zonally inhomogeneous Bickley jet are investigated. The equilibrated state consists of a full spectrum of waves with a dominant frequency ...

Abstract: This paper reexamines the structure of ageostrophic winds in a baroclinic wave presented by Lim, Holton, and Wallace. It is found that the nonzero growth rate is indispensible to the compete explanation of the observed ...

Abstract: The Geophysical Fluid Dynamics Laboratory (GFDL) hurricane initialization algorithm is implemented in the community fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model ...
