Method synopsis

High-resolution Weather Research and Forecasting model simulations using different microphysical parameterizations to assess precipitation sensitivity in complex mountain terrain. Three different microphysics schemes were tested with identical other physics parameterizations.

Synthesized from method descriptions across 2 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Cold-season precipitation sensitivity to microphysical parameterizations: hydrologic evaluations leveraging snow lidar datasets (2024), Journal of Hydrometeorology. Implementations in other papers (listed below) may differ.

1. WRF model configuration setup
   Configure WRF Model version 4.3.3 with two-way nested domain setup. Outer domain uses ~1-km horizontal resolution (230 × 349 grid cells) and inner domain uses ~1-km grid (349 × 391 grid cells). Use CFSv2 0.5° horizontal resolution lateral boundary and initial conditions provided every 6 h. Set two-week spinup period prior to 1 October start date.
   Quantities: 230 × 349 grid cells outer domain, 349 × 391 grid cells inner domain, 0.5° CFSv2 resolution, 6-hour boundary condition updates, 2-week spinupDuration: Simulations run from 1 October 2017 to 30 April 2018 and from 1 October 2018 to 30 April 2019Conditions: Cold season simulation periods covering snow accumulation season
   Equipment: WRF Model v4.3.3, CFSv2 climate reanalysis data
2. Microphysics scheme testing
   Run three WRF configurations with different microphysics schemes: Thompson (MP08), Morrison (MP10), and ISHMAEL (MP55). Keep all other physics parameterizations constant including Noah-MP land surface model, Monin-Obukhov surface layer, Mellor-Yamada-Janjic planetary boundary layer, and Community Atmosphere Model radiation schemes.
   Quantities: 3 different microphysics parameterizations testedDuration: Each scheme run for both water years (2018 and 2019)Conditions: Identical physics parameterizations except for microphysics scheme
   Equipment: Thompson microphysics scheme, Morrison microphysics scheme, ISHMAEL microphysics scheme
