Hypercane
From Wikipedia, the free encyclopedia
A hypercane is a theoretical class of tropical cyclone that could form if ocean temperatures reached around 50° Celsius (122° Fahrenheit)—15° higher than the warmest ocean temperature ever recorded.[1]—which could in turn be caused by a large asteroid or comet impact, a large volcanic or supervolcanic eruption, or very extensive global warming.[2] There is some speculation that some dinosaurs might have been killed off by a series of hypercanes, resulting from an asteroid or comet crashing into Earth.[3] The term was originally coined by atmospheric scientist Kerry Emanuel in 1996, at MIT.[4]

[edit] Phsical description
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]
[edit] Hypercanes in fiction
The anime Tactical Roar uses a fictional hypercane in the Pacific Ocean as a pretext to showcase naval battles, which are the series' focus.
