For those attempting to tune pgcon: ! The value of 0.55 comes from an observational study of ! synoptic-scale deep convection and 0.7 came from an ! incorrect fit to the same data. That value is likely ! correct for deep convection at gridscales near that of GFS, ! but is questionable in shallow convection, or for scales ! much finer than synoptic scales. ! Then again, the assumptions of SAS break down when the ! gridscale is near the convection scale anyway. In a large ! storm such as a hurricane, there is often no environment to ! detrain into since adjancent gridsquares are also undergoing ! active convection. Each gridsquare will no longer have many ! updrafts and downdrafts. At sub-convective timescales, you ! will find unstable columns for many (say, 5 second length) ! timesteps in a real atmosphere during a convection cell's ! lifetime, so forcing it to be neutrally stable is unphysical. ! Hence, in scales near the convection scale (cells have ! ~0.5-4km diameter in hurricanes), this parameter is more of a ! tuning parameter to get a scheme that is inappropriate for ! that resolution to do a reasonable job. !
