Info

Challenges • QPF problematic (too much convective precip) • Stratiform regions appear too small (microphysics?) • Convective systems often fail to decay (BL evolution?) • Lack of detail in initialization
Advances needed for convectivescale forecasting • Assimilation of small-scale structure (Doppler radar, etc.) • New techniques for TKE/PBL for 1-5 km grids • Shallow cumulus parameterization to improve convective initiation? • More accurate treatment of ice/liquid species in cloud microphysics • New verification techniques
