This study covers the entire life cycle of Hurricane Humberto (2007) including the formation of barotropic low, quick, near-land intensification, landfall, and dissipation. Using WRF-ARW, Humberto is modeled, allowing for evaluation of model accuracies in formation, intensity, track, and timing. A study was performed on the bogus data assimilation schemes of both the WRF-ARW and the GFDL using a case study on Hurricane Humberto, but didn't directly address the use of different model parametrization schemes and their effects on model accuracy (Xiao et al., 2009). Thus, running the ARW testing different parametrization schemes, allows for a study of the effect the parametrization schemes have on model accuracy.
