Abstract : Contrary to the indications of several past studies, numerous tropical cyclones, intensify after recurvature. The unexplained behavior has led to large intensity forecast errors. This study reveals two seasonal peaks of the behavior separated by a July minima in which intensification after recurvature (IAR) does not occur. A particular synoptic pattern is indentified. Monthly characteristics of IAR are explained as a function of physical parameters in the tropical cyclone's oceanic and atmospheric environment. Guidelines are provided to allow the forecaster to anticipate and react to IAR.
