Description
This PR brings in improvements, cleaning and tuning of the prognostic updraft velocity parameterization under the progomega flag in saSAS. The new parameterization improves the representation of updrafts and cloud base mass-flux compared with lidar observations.
Issues
Testing
The full UFS regression test suite has been run - new baselines are needed for tests using the saSAS convection scheme. Impact on the baselines are very minor coming from changes related to k > kbcon1 to k >= kbcon1 outisde of the progomega option.
