Systematic Model Error: The Impact of Increased Horizontal Resolution versus Improved Stochastic and Deterministic Parameterizations

Abstract:

Long-standing systematic model errors in both tropics and extratropics of the ECMWF model run at a horizontal resolution typical for climate models are investigated. Based on the hypothesis that the misrepresentation of unresolved scales contributes to the systematic model error, three model refinements aimed at their representation-fluctuating or deterministically-are investigated. Increasing horizontal resolution to explicitly simulate smaller-scale features, representing subgrid-scale fluc...
