H.F. Campos Velho and J.C.R.Claeyssen (1994): A Nonmodal Approach for Time-integration of a Barotropic Limited Area Model, Computers & Mathematics with Applications, Vol. 33, No. 9, pp 1-13.

Abstract: In this work we integrate a semi-discrete non-linear matrix differential system arising from a barotropic limited area model with periodic boundary conditions on the beta-plane. We use a new formulation for the state transition matrix, the non-modal matrix, in order to carry out the time-integration. The Helmholtz wind field reconstruction is performed by singular value decomposition (SVD).
