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]
Physical description
Hypercanes would have wind speeds of over 600 miles per hour,130 m/s, and would also have a central pressure of less than 700 hectopascals, giving them an enormous lifespan. This storm would have been produced by the super heated ocean waters in the asteroid's impact zone, creating a storm that would have been the size of Noth America, with a storm surge of 60+ feet and an eye over 200 miles accross. The waters would remain hot enough for weeks, allowing more hypercanes to be formed. Cite error: Closing </ref> missing for <ref> tag
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.
