Vous avez s\u00fbrement entendu parler des ouragans qui frappent les Antilles, mais vous \u00eates vous d\u00e9j\u00e0 demand\u00e9 d’o\u00f9 ils provenaient\u00a0? Je suis l\u00e0 pour r\u00e9pondre \u00e0 vos questions.<\/b><\/p>\n

Pour qu’un ouragan puisse se d\u00e9velopper, deux crit\u00e8res doivent \u00eatre r\u00e9unis. Le premier crit\u00e8re, le plus important, est la temp\u00e9rature de l’eau qui doit \u00eatre de plus de 26\u00b0. Celle-ci doit \u00e9galement \u00eatre profonde de plus 50 m\u00e8tres.<\/p>\n

On parle d’ouragan quand les vents d\u00e9passent 117km\/h. Sinon, on appelle ce ph\u00e9nom\u00e8ne une temp\u00eate tropicale. Le mot \u00ab\u00a0cyclone \u00ab\u00a0que vous connaissez tous est donc un synonyme de ce fameux \u00ab\u00a0ouragan\u00a0\u00bb\u00a0!<\/p>\n

Cependant, tant que l’eau au-dessus de laquelle se situe l’ouragan reste chaude, celui-ci peut continuer d’\u00e9voluer. Ainsi, l’ouragan Irma a atteint les 249 km\/h\u00a0! En effet, les eaux \u00e9taient anormalement chaudes \u00e0 cette zone de l’Oc\u00e9an Atlantique.<\/p>\n

\"\"<\/p>\n

La partie au centre de la d\u00e9pression se nomme \u00ab\u00a0l’oeil\u00a0\u00bb du cyclone, il n’y a ni vent ni pluie contrairement \u00e0 ce que l’on peut penser\u00a0!<\/p>\n

Et voil\u00e0, vous savez tous sur les ouragans et sur leur provenance\u00a0!<\/p>\n
