MPAS-Dev/MPAS-Model: MPAS Version 8.4.2

Le résumé fourni par la source

This bug fix release addresses several issues in the MPAS-Atmosphere model and in the MPAS infrastructure. Specific changes include: Fix an issue with the naming of MPAS's internal ESMF time-keeping library in CMake builds of MPAS. (PR #1506) Fix an issue with restart runs in MPAS-Atmosphere on GPUs. (PR #1503) Address a lack of TKE in MPAS-Atmosphere with the 1.5-order prognostic TKE option when there is no TKE in the initial conditions (for example, in real-data cases). (PR #1499) Correct the ordering of the lbc_ni and lbc_nr scalars in the atmosphere core's Registry.xml file. Note that unless LBCs are provided for ni and nr, the previously incorrect order of lbc_ni and lbc_nr would not affect results, as both fields would be filled with zero values. (PR #1498) Change the default value of the config_number_of_sub_steps namelist option from 2 to 4 in the atmosphere core's Registry.xml file to address an issue in convection-permitting simulations where noise can sometimes appear in the jet streams using the previous default value of 2. The noise, when present, also produces unphysical features in horizontal kinetic energy spectra at high wavenumbers. (PR #1496) Note: Increasing the number of sub-steps from 2 to 4 can be expected to increase the computational cost of the dynamics by ~10% and the computational cost of a full-physics simulation by ~5%. Work around an issue with continuation lines in instances of the PACKAGE_LOGIC_PRINT macro that prevented successful compilation of MPAS-Atmosphere with the nvfortran compiler. (PR #1495) Acknowledgements: Thanks to Trude Eidhammer (@trudeeidhammer) and Evan Parker (@eap) for identifying issues and providing fixes in this release.
