Did you know after Professor Kerry Emmanual at MIT coined the term Hypercane for a Hypothetical class of Tropical Cyclones it was put forward that Hypercanes may have played a role in the climate shifts after the Chicxulub impactor event that lead to the demise of the Non-Avian Dinosaurs.

After the impact water would have rushed back in heating to greater than 50ºC (Normal TCs just need 26.5ºC or 27ºC, and the warmest SSTs today are 34ºC), this is hypothesised to have set off a series of Hypercanes which damaged the Ozone layer; todays Tropical Cyclones only really just poke into the Stratosphere, a Hypercane due to the very intense convection would be even higher injecting water which can catalyse ozone breakdown.

Unlike how hypercanes are portrayed in fiction (as megasized storms) they're would be actually fairly compact systems, with central pressures bellow 700hPa and 800km/h winds, the extremely low central pressured would have allowed hypercane to survive for quite a while after being removed from the source of the heat, and the event if it did create hypercanes it would have been series for a few weeks until the thermal disequilebrium was closed up.
