Abstract: Application of the nonlinear normal mode initialization method requires the construction of the normal modes of the linearized model equations. In the case of a limited area model the Coriolis parameter in this linear ...

Abstract: A nonlinear normal mode initialization method with all of the beta terms included in the linearized model equations is formulated for a limited-area model. It is the extension of an earlier method examining the sensitivity ...

Abstract: A nonlinear normal mode initialization method is applied to a baroclinic limited arm forecast model. This method is very effective in reducing the amplitude of the rapid oscillations during the first hours of the forecast. ...

Abstract: In this paper the convergence of an iterative method for solving the nonlinear balance equation is analyzed. It is shown that this iterative method, originally proposed by Miyakoda and Shuman, is convergent if a sufficiently ...

Abstract: A wind field given over a limited domain can be partitioned into nondivergent and irrotational components in an infinity of ways. A particular solution, selected by requiring the velocity potential to vanish on the boundary, ...
