Tropical cyclone genesis efficiency
WebDec 1, 2014 · Tropical cyclone (TC) genesis is a process through which disorganized convective-scale cloud systems are developed into a self-sustaining cyclonic system with a warm core under favorable large-scale background conditions. WebJun 1, 2024 · Although many tropical cyclones form in the deep tropics (far removed from the influence of midlatitude systems), about 16% of global genesis events from 1948 to 2010 formed via tropical transition, during which a cold-core cyclone of baroclinic origin transitions into a warm-core tropical cyclone (Davis and Bosart, 2003; McTaggart-Cowan …

http://www.soest.hawaii.edu/~li/www/Geetal2012.pdf WebInteractions between these systems may lead to merger, growth to the surface, and development of both the nascent eye and inner rainbands of a tropical cyclone. The process is essentially stochastic, but the degree of stochasticity can be reduced by the continued interaction of the mesoscale systems or by environmental influences.
WebJul 15, 2024 · Abstract Globally, the highest formation rate of super tropical cyclones (TCs) occurs over the Bay of Bengal (BoB) during the premonsoon transition period (PMT), but TC genesis has a low frequency here. TCs have occurred over the BoB in only 20 of the past 36 years of PMTs (1981–2016). This study investigates which environmental conditions … http://www-das.uwyo.edu/~geerts/cwx/notes/chap13/trop_cyclogenesis.html

WebJan 1, 2006 · The genesis efficiency is linked to the structure of the initial disturbance. Numerical studies suggested that the initial disturbance comprised of a mid-level vortex …
Areas farther than 30 degrees from the equator (except in the vicinity of a warm current) are not normally conducive to tropical cyclone formation or strengthening, and areas more than 40 degrees from the equator are often very hostile to such development. The primary limiting factor is water temperatures, although higher shear at increasing latitudes is also a factor. These areas are …
