Description:

In ccpp-physics submodule, added explicit 'alpha_fd' coefficient to drag_suite.F90 which corresponds directly to 'alpha' coefficient in Beljaars et al. (QJRMS, 2004), which by default is 12.0. The coefficient will be a runtime namelist option, and can control the strength of the turbulent orographic form drag (TOFD).
Note that the runtime results are bit-for-bit identical to those of the previous version unless a value other than alpha_fd = 12.0 in the namelist.
In ufs-weather-model, updated .gitmodules and added Regressions test log.

Changes

Regression Test Changes (Please commit test_changes.list):

• No Baseline Changes.

Regression tests have been performed on Hera with the Intel and Gnu compilers. The tests involving ugwpv1 all passed for both intel and gnu compilers, however, some of the other gnu tests failed. These tests also failed with the previous commit, so failures don't appear to have to do with the code changes in this PR.

Input data Changes:

• None.
