Abstract

The summer precipitation bias over the central US is a persistent challenge for climate models and it is closely linked to surface temperature bias. The Energy Exascale Earth System Model (E3SM) v1 Atmosphere Model (EAM) has implemented many new features in the physical parameterizations and developed two different horizontal resolutions: 1o (ne30) and 0.25o (ne120). Each resolution has its own tuning parameter setting. It is important to assess the persistent precipitation bias over the central US in EAM v1 and exam how the bias respond to different model settings.
