Abstract: The implementation of a progressive Fourier transform, applied to time series representative of the El Niño?Southern Oscillation (ENSO), provides a visual review of the frequency modes that have dominated throughout the ...

Abstract: A semi-implicit, control-volume, nonhydrostatic model is presented. Advection is fifth order with respect to space. Boundary conditions and molecular fluxes are also formulated at fourth order with respect to space. ...

Abstract: A method is described that estimates the time evolution of surface divergence and other secondary circulation properties of an ocean eddy. The method is novel because it is applied to the observations of a single surface ...
