Hurricane Winds at Landfall

We are currently supported by the National Science Foundation to investigate the effects of land and the urban environment on the hurricane wind field during landfalls. We are using both in-situ measurements of hurricane winds, large-eddy simulations, and even wind tunnel experiments to better understand how the hurricane wind fields changes as it moves onto land and into suburban and urban areas. We hope to use these results to improve the near-surface wind field predictions in both research and forecasting models.
