The Extratropical Transition of Tropical Cyclones
The objective is to investigate the physical processes that occur as a tropical cyclone interacts with the environment such that intensity and structure changes occur. Specific interactions being studied are with baroclinic environments in the midlatitudes during extratropical transition. During extratropical transition, radical changes to the storm structure occur as vertical wind shear and in...
متن کاملExtratropical and Tropical Transition
Extratropical and tropical transition each represents an end of the tropical cyclone lifecycle. Extratropical transition, along with dissipation, represents the end of the tropical cyclone lifecycle. Conversely, tropical transition represents a unique beginning to the tropical cyclone life cycle. In this lecture, we aim to describe both, focusing primarily on the extratropical transition proces...
متن کاملExtratropical Transition of Southwest Pacific Tropical Cyclones. Part I: Climatology and Mean Structure Changes
A database of tropical cyclone best track and intensity information for the southwest Pacific Ocean basin is used to construct a 28-year climatology for tropical cyclones that move into middle latitudes. Of the nine or so tropical cyclones that form each year, an average of about three can be expected to migrate south of 358S, with the greatest fraction in March. Storms entering the Tasman Sea ...
متن کاملSIXTH INTERNATIONAL WORKSHOP on TROPICAL CYCLONES Topic 2.4 : Observing and Forecasting of Extratropical Transition Rapporteur:
At IWTC-V in Cairns, Australia, researchers and forecasters agreed that a research program focusing on important physical characteristics associated with the extratropical transition (or “ET”) of tropical cyclones (TC) was needed. This research program should promote analysis of existing observational and modeling datasets to: (i) improve analyses and prediction of the structure changes, signif...
متن کاملThe Impact of air-sea interaction on the extratropical transition of tropical cyclones
Tropical cyclones moving polewards into the midlatitudes and undergoing extratropical transition are frequently associated with a significant decrease in predictability. This can be associated both with the system undergoing ET and with the flow downstream of the system (Harr et al. 2008; Anwender et al. 2008). Forecast errors are not only associated with strong ET events. For example, the medi...
