Hypercane
A hypercane is a theoretical class of hurricane that could form if ocean temperatures reached around 50° Celsius (122° Fahrenheit)—15° higher than the warmest ocean temperature[1]—which could in turn be caused by an asteroid impact, a large volcanic eruption, or extensive global warming.[2] There is speculation that dinosaurs might have been killed off by a series of hypercanes, resulting from an asteroid crashing into Earth.[3] The term was originally coined by atmospheric scientist Kerry Emanuel in 1996, at MIT.[4]
Hypercanes would have wind speeds of over 130 m/s, but would also have a central pressure of less than 700 hectopascals, giving them an enormous lifespan.[4]
The anime Tactical Roar uses a fictional hypercane in the Pacific Ocean as a pretext to showcase naval battles, which are the series' focus.
