  abstract = {{T}ropical cyclones ({TC}s) can have profound effects on the dynamics of forest vegetation that need to be better understood. {H}ere, we analysed changes in forest vegetation induced by {TC}s using the normalized difference vegetation index ({NDVI}). {W}e used an accurate historical database of {TC} tracks and intensities, together with the {W}illoughby cyclone model to reconstruct the 2{D} surface wind speed structure of {TC}s and analyse how {TC}s affect forest vegetation. {W}e used segmented linear models to identify significant breakpoints in the relationship between the reconstructed maximum sustained wind speed ({W}max) and the observed changes in {NDVI}. {W}e tested the hypothesis that the rate of change in damage caused by {TC}s to forest and recovery time would increase according to {W}max thresholds as defined in the widely used {S}affir-{S}impson hurricane wind scale ({SSHWS}). {W}e showed that the most significant breakpoint was located at 50 m/s. {T}his breakpoint corresponds to the transition between categories 2 and 3 {TC}s in the {SSHWS}. {B}elow this breakpoint, damages caused to forest vegetation and the time needed to recover from these damages were negligable. {W}e found a second breakpoint, with a sharp increase in damages for winds >75 m/s. {T}his suggested that extremely intense tropical cyclones, which might be more frequent in the future, can cause extreme damages to forest vegetation. {N}evertheless, we found high variation in the observed damages and time needed to recover for a given {W}max. {F}urther studies are needed to integrate other factors that might affect the exposure and resistance to {TC}s as well as forests' capacity to recover from these disturbances.},
