Evaluating the effects of latent heating in tropical cyclone Sinlaku's extratroplical transition using ARW and energetics analysis
Of all the Tropical Cyclones (TC) that occur worldwide, 42% (27%) of the North Atlantic (western North Pacific) storms undergo Extratropical Transition (ET) into Extratropical Cyclones (EC). EC are asymmetric cold core systems as opposed to their warm core predecessors, and their radii of gale force...

Of all the Tropical Cyclones (TC) that occur worldwide, 42% (27%) of the North Atlantic (western North Pacific) storms undergo Extratropical Transition (ET) into Extratropical Cyclones (EC). EC are asymmetric cold core systems as opposed to their warm core predecessors, and their radii of gale force winds (17msâťÂš) may increase by a factor of two to three times their original radii. This expansion of the gale force winds can cause a significant amount of damage. In addition, these ET can trigger and amplify upper atmospheric waves, indirectly leading to the generation of other powerful storms across the world, which makes it imperative to study the dynamics and energetics involved with the ET. The ET of TC Sinlaku (2008), with the aid of a 500mb shortwave, was well observed through an international field campaign, THORPEX Pacific-Asian Regional Campaign (T-PARC). To understand the effects of latent heating when Sinlaku transitioned, this study has followed similar techniques to Kuo et al. (1990). Two different sets of simulations using the Weather Research and Forecasting (WRF) model with the Advance Research WRF core were conducted, involving a full set of physics and fake dry physics (neglecting latent heating).
