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.
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.
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)
A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]
On the other end of the spectrum, wedge tornadoes can have a damage path a mile (1.6 km) wide or more. A tornado that affected Hallam, Nebraska on May 22, 2004, was up to 2.5 miles (4.0 km) wide at the ground, and a tornado in El Reno, Oklahoma on May 31, 2013, was approximately 2.6 miles (4.2 km) wide, the widest on record.
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.
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 ...
