Establishing closer collaboration to improve model physics for short-range forecasts

The numerical weather prediction (NWP) workshop on model physics with an emphasis on short-range prediction, July 26-28, 2011, Maryland, identified near-term opportunities for making urgently needed physics improvements in the models. The workshop also established a longer-term framework for closer collaboration between research and operations in the development of forecast model physics. Topics discussed include representation of physics processes in NWP models, including atmospheric radiation, land surface modeling, and cloud microphysical processes. The workshop participants recommended the some action items such as EMC to establish a science advisory board and EMC and the DTC to work closely to promote R&O collaboration through working group meetings and workshops. The members also highlighted that NOAA/NWS should acquire increased computing resources for developing the next-generation high-resolution deterministic and ensemble modeling systems.
