3b. Numerous changes are made to convective parameterization
- Water loading effects are now included in assessing the buoyant instability of parcels from which a revised (lower) cloud top is determined to be at the highest level of positive buoyancy.
- The latent heat of vaporization used to calculate equivalent potential temperatures during model integration is made to be consistent with the value used in generating the initial lookup tables.
- The first-guess reference temperatures in the upper-half of shallow convective clouds are limited to be no more than -1 deg C colder than the ambient temperature.
