Hypercanes would have wind speeds of over 800 kilometres per hour (500 mph), potentially gusting to 970 km/h (600 mph), [7] and would also have a central pressure of less than 700 hectopascals (20.67 inHg), giving them an enormous lifespan of at least several weeks. [5]
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 ...
Hypercane, hypothetical extreme tropical cyclones that could reach the size of continents and last for several weeks on average. Hypercanes also would have maximum sustained winds reaching at least 500 miles per hour (800 km/h), and a minimum central pressure of 700 millibars (21 inHg) or lower.
Such a storm would produce winds of over 800 km/h (500 mph). A series of hypercanes may have formed during the asteroid or comet impact that killed the non-avian dinosaurs 66 million years ago. Such a phenomenon could also occur during a supervolcanic eruption, or extreme global warming.
The number of $1 billion Atlantic hurricanes almost doubled from the 1980s to the 2010s, and inflation-adjusted costs have increased more than elevenfold. [1] The increases have been attributed to climate change, more people moving to coastal areas, [1] and the dramatic increase in construction costs since 1980.
Yardeni then sees the index reaching 7,000 by the end of 2025, 8,000 by the end of 2026, and 10,000 by the end of the decade. Previously, Yardeni told Yahoo Finance he'd seen the S&P 500 hitting ...
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)
With maximum sustained winds of 215 mph (345 km/h) and a minimum pressure of 872 mbar (hPa; 25.75 inHg), Patricia is the most intense tropical cyclone ever observed in the Western Hemisphere. In terms of central pressure, it is also the second-most intense tropical cyclone ever recorded worldwide, just shy of Typhoon Tip in 1979 which had a ...
