The waters after a hypercane could remain hot enough for weeks, allowing more hypercanes to form. A hypercane's clouds would reach 30 to 40 km (20 to 25 mi) into the stratosphere. Such an intense storm would also damage the Earth's ozone layer, potentially having devastating consequences for life on Earth.
Then in 1995 a new theory claimed that a powerful mega-storm known as a hypercane caused the extinction. The hypercane allegedly reaches 20 miles into the stratosphere and has wind speeds of up to 500 miles per hour. 3-D computer graphics will reveal how this storm could have brought down nearly all life on the planet. One of six episodes about ...
Fixed: 130 m/s is approximately 500 kilometers/hour, not 500 miles/hour. Winds could speculatively and conceivably get as fast as the latter, but the lower boundary (where the analytical hurricane solution falls apart and a numerical hypercane one starts to be needed, at least on paper) is the former. 142.104.60.203 02:50, 25 August 2007 (UTC)

The 55 m/s (200 km/h; 120 mph; 107 kn) winds extend out to about 60 km (37 mi). The paper also specifically says the top speeds are at a radius of 6 km, so the eye must be less than 12 km in diameter, which completely contradicts the statement in the article that the eye would be 300 km in diameter.
Now known as the "Tropical Cyclone Report". A report summarizing the life history and effects of an Atlantic or eastern Pacific tropical cyclone. It contains a summary of the cyclone life cycle and pertinent meteorological data, including the post-analysis best track (six-hourly positions and intensities) and other meteorological statistics.
Permian–Triassic boundary at Frazer Beach in New South Wales, with the End Permian extinction event located just above the coal layer [2]. Approximately 251.9 million years ago, the Permian–Triassic (P–T, P–Tr) extinction event (PTME; also known as the Late Permian extinction event, [3] the Latest Permian extinction event, [4] the End-Permian extinction event, [5] [6] and colloquially ...
