Question about Availability and Configuration of the Scale-Aware Tiedtke Scheme in MPAS

Hello everyone,

I am currently using MPAS to simulate tropical cyclone tracks and to evaluate the impact of different physics parameterization schemes on the simulation results. The official MPAS distribution provides two primary physics suites. Based on my tests, the new-Tiedtke convection scheme within the mesoscale physics suite produces relatively better track simulations.

However, one of the key advantages of MPAS is its variable-resolution capability. When I tested a variable-resolution configuration (e.g., 60–3 km) using a convection-permitting setup, the simulation biases became substantially larger compared to the mesoscale configuration.

Recently, I came across a paper by Wang et al. (https://doi.org/10.1175/WAF-D-21-0179.1), which describes a newly developed scale-aware Tiedtke convection scheme designed to better adapt across different resolutions. I am very interested in applying this scheme to my experiments.

I would like to ask: Has this scale-aware Tiedtke scheme already been implemented and made publicly available in MPAS? If so, could you please advise how to configure and activate this scheme in MPAS (e.g., required namelist settings or code branches)?

Thank you very much for your help.
 
Hi,

The scale-aware Tiedtke scheme has been incorporated into MPAS-v8.0 and newer version. To run this scheme, you need to set

config_convection_scheme = 'cu_ntiedtke'

Please try and let me know if you have any questions.
