The process in which an extratropical cyclone undergoes a rapid drop in atmospheric pressure (24 millibars or more) in a 24-hour period is referred to as explosive cyclogenesis, and is usually present during the formation of a nor'easter. [2] Similarly, a tropical cyclone can undergo rapid intensification.
The Northwest Pacific sees tropical cyclones year-round, with a minimum in February and a peak in early September. In the North Indian basin, storms are most common from April to December, with peaks in May and November. [24] In the Southern Hemisphere, tropical cyclone activity generally occurs between early November and April 30.
Hurricane Beulah in 1967 was the first tropical cyclone to have its eyewall replacement cycle observed from beginning to end. [11] Previous observations of concentric eyewalls were from aircraft-based platforms. Beulah was observed from the Puerto Rico land-based radar for 34 hours during which time a double eyewall formed and dissipated. It ...
A tropical cyclone is a storm system characterized by a low-pressure center and numerous thunderstorms that produce strong winds and flooding rain. [45] A tropical cyclone feeds on heat released when moist air rises, resulting in condensation of water vapour contained in the moist air. [45]
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]
Many theories exist as to the exact process by which the eye forms: all that is known for sure is that the eye is necessary for tropical cyclones to achieve high wind speeds. [12] The formation of an eye is almost always an indicator of increasing tropical cyclone organisation and strength.
The 2024 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. It was above-average in terms of depressions and average in terms of formation of cyclonic storms. [1] Seasons have no official bounds, but cyclones tend to form between April and December, with the peak from May to Early November.
A vortex may consolidate into a tropical cyclone in either the eastern Pacific or western Atlantic and detach from the gyre if the environment is conducive to tropical cyclone development. [3] [1] [6] This occurs about once every other year on average, [1] and tropical cyclone development occurs in tandem with around half of all CAGs. [8]
