Implication

Coupled simulation reveals that soil data discrepancies alter energy fluxes and atmospheric stability in southern Africa, highlighting broad uncertainties in regional water cycle models.

Key Points

Soil hydrophysical properties markedly alter regional surface water and latent heat fluxes, significantly modifying convective available potential energy across southern Africa.
Convection-permitting coupled WRF-Hydro simulations with the Noah-MP land surface model across four global soil datasets show reduced water capacity lowers convective inhibition.
Highlights critical uncertainties in modeled water cycles, as soil data discrepancies alter atmospheric moisture convergence and land-atmosphere coupling across diverse climatic zones.
