Abstract This study examines the changes in boundary layer of landfalling tropical cyclones. Several storms which made landfall near surface observation platforms capable of high resolution data storage were examined. These records were subjected to spectral methods to explore the characteristics of the changing boundary layer turbulence. These results were compared to recent observations of boundary layer roll features noted in some landfalling storms. Spectra were also used for determining turbulence dissipation rates in the storms. It was determined that only the highest resolution datasets available with a sampling rate of 5 Hz were adequate to explore the small scale features of the flow and to accurately describe the turbulence dissipation rates.
