Cyclone Zoe was near its record peak intensity on late December 27, 2002 when this image was captured by the Moderate Resolution Imaging Spectroradiometer on NASA's Terra satellite. Cyclone Zoe was one of the most intense tropical cyclones ever observed in the South West Pacific Ocean .
The season began with an early start, with the formation of the first tropical cyclone on 29 July, which was only recognized as a tropical cyclone during post-season analysis. This was the second time that a tropical cyclone had formed during July. The other one was Cyclone Lindsay in the 1996–1997 season.
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]
Common developmental patterns seen during tropical cyclone development, and their Dvorak-assigned intensities. The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared ...
Mesocyclones form when strong changes of wind speed and/or direction with height ("wind shear") sets parts of the lower part of the atmosphere spinning in invisible tube-like rolls. The convective updraft of a storm then draws up this spinning air, tilting the rolls' orientation upward (from parallel to the ground to perpendicular) and causing ...
Traditionally, areas of tropical cyclone formation are divided into seven basins. These include the North Atlantic Ocean, the eastern and western parts of the North Pacific Ocean, the Southwest Pacific, the Southwest and Southeast Indian Oceans, and the North Indian Ocean (Arabian Sea and Bay of Bengal). The West Pacific is the most active and ...
Officials are assessing damage after Cyclone Chido devastated the island of Mayotte over the weekend.. The worst storm to hit the Indian Ocean islands in approximately 100 years, Chido's 124 mph ...
As the cyclone is essentially a two phase particle-fluid system, fluid mechanics and particle transport equations can be used to describe the behaviour of a cyclone. The air in a cyclone is initially introduced tangentially into the cyclone with an inlet velocity . Assuming that the particle is spherical, a simple analysis to calculate critical ...
