MYNN surface Layer Upate

[joeolson42]

MYNN surface-layer scheme update:

Updates from RRFS_dev, which include updates made for RRFS "Base E" (negligible impact on forecasts beyond the first 10 or so timesteps) + some addition mods below:

• Reintroduce u* averaging over water, which can help reduce the noisy 10-m winds in the hurricane regime. This has little or no impact in any other regime.
• Clean-up of the model constants. There was actually a benign bug found with a constant coming in from the interface AND the "use phys_constants". Also, g was defined globally and in some subroutines. This can be further cleaned up later, but this takes out all known issues.
• Changed "kind=kind_phys" to just "kind_phys", which was requested in a previous PR.
• Updated some comments that were out of date.

Top of commit queue on: TBD

@jkbk2004 - Apparently this also needs to be merged before the end of April. Is there a way to make that happen?

[jkbk2004]

We have a flexibility for the rest of the week. It's likely to work on the combined PRs #1660 + #1646 today or tomorrow, right? If we let the combined PRs go today, we still have time for this pr either tomorrow or Friday. If you like to combine all 3 PRs together, that's still possible and we can schedule like tomorrow to give enough time for pre-test. #1672 is on-going. I think it will be merged this afternoon.

[SamuelTrahanNOAA]

I'll work on merging #1678 into #1646

[joeolson42]

The gnu tests look ok. I'm running the intel tests now (on hera). Will upload results later today. Sam, thanks for doing the merge.

@SamuelTrahanNOAA #1672 was merged. Let me know if you want us to wait for #1646 (combined with this one and #1660) to be ready. Or we can go for another pr #1685 for minor change on cmeps and ww3. @zach1221 FYI

[SamuelTrahanNOAA]

You should commit #1646 next. I am working on updating it right now.

[SamuelTrahanNOAA]

I have updated #1646; it is up-to-date with develop. Also, my tests of the combination of 1660+1646+1678 passed on hera.intel and hera.gnu before I merged 1672. The Jet tests are still running, but it is extremely rare for the tests to pass on hera.intel and fail on jet.intel.

[jkbk2004]

Merged with #1646
