Terrence McGuinness contributed to the TerrenceMcGuinness-NOAA/global-workflow repository by tuning the orographic gravity wave drag (OGWD) parameterization for high-resolution weather modeling grids. He adjusted the effective grid size factor for OGWD from 6.0 to 2.0 for resolutions below 10 km, directly increasing OGWD magnitude and improving forecast skill for fine-scale grids such as C1152. This targeted configuration management work, implemented using Shell scripting, addressed the need for more accurate physical representation in high-resolution forecasts. The change was fully documented, linked to issue tracking, and integrated into the workflow, reflecting a focused and technically sound engineering approach.
