Abstract: The mechanism of nonlinear wavenumber selection for single-wave steady states is examined analytically and numerically in an Eady-type model with uneven Ekman dissipation. The spectral solution is truncated to three zonal ...

Abstract: we use truncated spectral Eady models with two Ekman layers of different strength to investigate the baroclinic flow transitions observed in annulus experiments. Our analysis is both analytical and numerical As the dissipation ...

Abstract: An intercomparison study of the evolution of large-scale circulation features during TOGA COARE has been carried out using data from three 4D assimilation systems: the National Meteorological Center (NMC, currently known ...
