We are implementing a boundary layer scheme for WRF that incorporates recent advances in the understanding and modeling of both stable and convective boundary layers. The stable side of the scheme is the Total Turbulent Energy closure advanced by Mauritsen et al. (JAS 2007). On the convective side, we use an eddy diffusivity - mass flux scheme described by Angevine (JAM 2005). The latter also integrates transport by non-precipitating cumulus. The complete scheme should improve model performance in two areas where current models are known to be deficient, that is, stable boundary layers and boundary layers with shallow cumulus. Results of 1D tests on established test cases will be shown.
