An Estimation of Optimum Grid Size for Kashmir Valley by Spectral Method

Abstract

In many of the short-range numerical weather prediction models, an accurate specification of grid size is essential in mountainous and valley regions to adequately represent terrain forcing without resorting to subgrid-scale parameterization. Since the geomorphology of the earth is quite varied, an improper specification of grid size will neither be adequate nor realistic. In this study, the spectral method is used to determine the required optimum horizontal grid size for numerical simulations enclosing Kashmir Valley and its surroundings.
