I am trying to get wrf namelist.input physics options that can optimize the output results (wind map) compared to observed meteorological data in east-Africa region. I need the options for tropical region.
Nothing is rigid in terms of set of parameterizations for any specific location. You have to do hit-and-trial sets of parameterization schemes to compare with your observations during the study period. It's an extensive work; there are no short-cuts.
Although you may get a reasonable comparisons with some set of parameterizations, you have to know that you have just tweaked the model to get the reasonable estimates. However, they are not as good predictions as we think they are because of the nature of the parameterizations included in the models including WRF.
