Furthermore, surface observations are compared with high-resolution cloud-resolving models like MM5 and WRF, also with ocean coupled models like UMCM and CWRF. Results indicate that H-Wind may have overestimated the wind speed in the inner core and underestimated in the outer regions in Hurricane Ike. The uncoupled atmospheric models, MM5 and WRF, overpredict surface winds compared to the observations, largely due to the lack of coupling to the ocean. But, with the track error of each model, precise evaluations are difficult to make. The results presented in this study suggest that more analysis of both the observations and model forecasts are needed to further examine the full range of surface wind speeds, not just the maximum winds in hurricanes. As well it is essential to estimate the uncertainty of observations and model forecast.
