These upgrades include:
Increase in horizontal resolution from 35 km to 27 km grid spacing (still 64 vertical layers).
The high resolution part of the GFS will be extended from F180 to F192
Improvements to the shallow and deep convection parameterizations
Replacement of shortwave radiation from NASA based version with random cloud overlap to AER based RRTM with maximum/random cloud overlap
Inclusion of vertical advection of moisture, ozone and cloud condensate based on positive definite advection scheme
Changes to boundary layer scheme and gravity wave drag
Maximum wind gusts variable added.
Testing shows a dramatic reduction in grid point storms (colloquially known as “precip bombs” or “grid-scale feedback”), which have historically plagued the GFS. Tropical cyclone tracks and intensity have also shown improvement.
