Hurik\u00e1ny jsou nejimpozantn\u011bj\u0161\u00ed bou\u0159e na Zemi. Tyto obrovsk\u00e9 spir\u00e1ly, kter\u00e9 vznikaj\u00ed nad tepl\u00fdmi vodami tropick\u00e9ho Atlantsk\u00e9ho oce\u00e1nu, se \u017eenou na z\u00e1pad a zanech\u00e1vaj\u00ed za sebou stopu zk\u00e1zy.

Satelity ESA sledovaly hurik\u00e1n Dean, jeho\u017e v\u011btry o rychlosti 260 km\/h vyvol\u00e1valy obrovsk\u00e9 vlny a sr\u00e1\u017eely budovy k zemi.
