Physics (PBL and convections) update for HR2 #1012

Closed Qingfu-Liu closed 1 year ago

Qingfu-Liu commented 1 year ago

This PR is created for HR2 with the updated PBL & convection codes (code from Jongil Han). I have resolved the conflicts of the codes with the current repository. The overall features for the updates are:

  1. In order to reduce the negative hurricane intensity biases, a parameterization for environmental wind shear effect is included in the GFS cumulus convection and TKE-EDMF PBL schemes. In addition, the entrainment rates in the GFS cumulus convection and TKE-EDMF PBL schemes are enhanced proportional to the sub-cloud or PBL mean TKE (turbulent kinetic energy) when TKE is larger than a threshold value.

  2. A detailed description and test results with the NCEP GFS for the impacts of the new parameterization of environmental wind shear effect and TKE-dependent entrainment enhancement on hurricane intensity and track forecasts are given here.

  3. In order to enhance the underestimated CAPE forecasts in the GFS, the entrainment rate in the TKE-EDMF PBL scheme is increased as a function of vegetation fraction and surface roughness length. A detailed description and test results with the NCEP GFS for this update are given here.

There is something wrong with this PULL request. Only 6 files are changed, but the pull shows there are 30 files changed

Looks like it should be committed to ufs-community/ccpp-physics instead of NCAR/ccpp-physics?

Qingfu-Liu commented 1 year ago

Lisa, you are right. I tried to create a fork from ufs-community/ccpp-physics, but can't (no permission). So I used my old CCPP fork which is created from NCAR ccpp. I am asking Grant to help me to fix this.
