Severe tropical cyclones with near surface sustained wind speeds equal to or exceeding 33 ms¡1 (120 km h¡1, 64 kn) are CYCLONES Tropical cyclones are intense, cyclonically1-rotating, low-pressure weather systems that form over the tropical oceans. High speed winds with severe rain are called cyclones. Cyclone is the general term for a variety of low pressure system types, such as tropical cyclones, extra tropical cyclones and tornadoes. Intense means that near surface sustained2 wind speeds exceed 17 ms¡1 (60 km h¡1, 32 kn). They are classified as large, traveling, cyclonic storms up to 2000 kilometers in diameter with centers of low atmospheric pressure. Les cyclones tropicaux ont un diamètre, en général de quelques centaines de kilomètres mais ils peuvent atteindre, 1000 voir même 1500 km et leurs structures nuageuses peuvent atteindre 20 km hauteur. • Students discuss in pairs dangers of tropical cyclones.
