Incipiunt fere omnes tempestates marinae in regionibuspressionisaeris demissae, quae ventos violentos et inundationes per se circumagentes efficiunt. Eae tempestates naturaliter annumerantur secundum sui venti celeritatem. Depressiones tropicae ventos habent minores quam 17 m/s (62 km/h), tempestates tropicae (sive procellae[2]) ventos inter 17 m/s et 33 m/s (62 et 118 km/h), et typhones marini ventos qui 33 m/s (118 km/h) excedunt.[4] De typhonum marinorum magnitudine deinde systema Saffir-Simpson NOAA quinque gradus additionales distinguit:[5] gradum primum ventibus inter 33 m/s et 41 m/s (118 et 153 km/h), secundum ventibus inter 41 m/s et 49 m/s (154 et 177 km/h), tertium ventibus inter 49 m/s et 58 m/s (178 et 209 km/h), quartum ventibus inter 58 m/s et 69 m/s (210 et 249 km/h), quintum ventibus qui excedunt 69 m/s (249 km/h). Typhones gradus quinti ventos tam rapidos habent ut magnas alluviones 6 m super maris aequor et magnum exitium tectis aedificationibusque efficiant.
Nomina typhonum marinorum anno 2006 in Mari Atlantico Septentrionali
Meteorologi solent dare nomina propria tempestatibus quando status "tempestatum tropicarum" attingunt. Exempli gratia anno 2006 nomina typhonum marinorum fuerunt:
↑Vide paginam Typhon apud Vicipaediam Anglicam: "Typhon is also the father of hot dangerous storm winds which issue forth from the stormy pit of Tartarus, according to Hesiod. His name is apparently derived from the Greek "typhein", to smoke, hence it is considered to be a possible etymology for the word typhoon, supposedly borrowed by the Persians (as طوفان Tufân) and Arabs to describe the cyclonic storms of the Indian Ocean. The Greeks also frequently represented him as a storm-daemon, especially in the version where he stole Zeus's thunderbolts and wrecked the earth with storms (cf. Hesiod, Theogony; Nonnus, Dionysiaca)."
