On Scalar and Vector Transform Methods for Global Spectral Models

On Scalar and Vector Transform Methods for Global Spectral Models We compare scalare and vector transform methods for global spectral models of the shallow-water equations. For the scalar transform methods, we demonstrate some economies in the number of Legendre transforms required. It is shown that the vector transform method is algebraically equivalent to the more usual scalar transform methods, and the choice of transform grid is discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Monthly Weather Review American Meteorological Society

Abstract

We compare scalare and vector transform methods for global spectral models of the shallow-water equations. For the scalar transform methods, we demonstrate some economies in the number of Legendre transforms required. It is shown that the vector transform method is algebraically equivalent to the more usual scalar transform methods, and the choice of transform grid is discussed.
