38 | | The strength of the nudging strongly depends on the nudging time scale used. Usually, this time scale should be in the order of several hours. By varying the nudging time scale with height it is possible to apply the nudging not everywhere but for example only above the boundary layer. In case this is wanted, the time scale should be set to a very large number (~10^10^) inside the boundary layer. By this way, the nudging tendency will approach zero. |
