A new dynamical core for the Met Office's global and regional modelling of the atmosphere

A computational scheme suitable for numerical weather prediction and climate modelling over a wide range of length scales is described. Its formulation is non‐hydrostatic and fully compressible, and shallow atmosphere approximations are not made. Semi‐implicit, semi‐Lagrangian time‐integration metho...

Description
Summary:A computational scheme suitable for numerical weather prediction and climate modelling over a wide range of length scales is described. Its formulation is non‐hydrostatic and fully compressible, and shallow atmosphere approximations are not made. Semi‐implicit, semi‐Lagrangian time‐integration methods are used. The scheme forms the dynamical core of the unified model used at the Met Office for all its operational numerical weather prediction and in its climate studies. © Crown copyright, 2005.
