## Abstract An economical explicit integration scheme for numerical weather prediction models is described. A splitting technique is used, in which the horizontal advection terms in the governing equations are integrated with a timestep limited by the wind speed, whilst the terms which describe gra

Abstract
Two minor numerical instabilities in the split explicit integration scheme are identified and remedies which have been developed are described. Some results of these refinements are presented.

## Abstract A splitβexplicit finite difference scheme is developed which combines the accuracy and economy required for numerical weather prediction with the conservation properties required for climateβchange experiments. Results are presented to demonstrate the scheme working in practice.
Splitting methods are frequently used for the solution of large stiff initial value problems of ordinary differential equations with an additively split right-hand side function. Such systems arise, for instance, as method of lines discretizations of evolutionary partial differential equations in ma
