The atmospheric momentum budget. Zonal averages (land points only) of a total parameterized surface stress, and contributions from b the turbulent friction and turbulent orographic form drag, and c low-level blocking and orographic gravity wave drag, from the results submitted by different groups to the Working Group for Numerical Experimentation of the World Meteorological Organization Drag project, for short range forecasts for January 2012
