 Another explanation is the absence of dry land between the south seas and the shores of the Sud sauvage (the southeastern part of the island), which means that the screaming sixties and the furious fifties (terms invented by mariners to describe the powerful winds between those longitudes) can reach Réunion without meeting any obstacle.A third reason is that this French Overseas department lies in the path of the tropical cyclones that arise in the centre of the Indian Ocean.The word "battant" as used here is not covered by any of the definitions given by the "Trésor de la langue française informatisé".
