Biases in CMIP6 Historical U.S. Severe Convective Storm Environments Driven by Biases in Mean‐State Near‐Surface Moist Static Energy

Abstract This work evaluates how well Coupled Model Intercomparison Project 6 models reproduce the climatology of North American severe convective storm (SCS) environments in ERA5 reanalysis and examines what drives biases across models. Biases spring SCS vary widely magnitude spatial pattern, though most do reproducing climatological pattern a few (MPI CNRM) also overall magnitude. are driven by extreme available potential energy. These ultimately found to be mean‐state near‐surface moist static energy, indicating that depend strongly on mean state. Results similar for fall, but not summer or winter when free‐tropospheric important. differ parent weakly child same parent. outcomes help identify well‐suited studying climate effects environments.
