Sensitivity of the boundary layer energy fluxes to forcing parameters in a simple climate model

Abstract

Winter and summer surface temperatures and time-averaged boundary layer energy fluxes are calculated by utilizing the Saltzman-Ashe parameterization for boundary layer fluxes in a two-level static model. The results are found to agree with observed patterns. Within the framework of this simple model, sensitivity analyses of the time-averaged boundary layer energy fluxes are conducted. Based on these results some of the forcing parameters (such as the subsurface temperature, cloud cover, surface albedo etc.) are arranged in a hierarchical order of importance. A generalized method of sensitivity analysis is also suggested.
