Overview of the Application of Orographic Data in Numerical Weather Prediction in Complex Orographic Areas

Complex orography is still a big challenge for all numerical weather prediction (NWP) models. Orography an important factor that affects the NWP results. The in mainly main accuracy of results through two aspects: orographic representation models dynamics and orography-related parameterization schemes physical processes. To ensure results, it necessary to have comprehensive understanding application data NWP. This paper summarized influence on weather, accuracy, parametrization drag Finally, this elaborates problems looks forward future directions field, hoping improve performance complex areas provide reference better
