Extratropical Transition
Extratropical Transition : The transformation of a tropical cyclone into an extratropical cyclone. More than 40% of Atlantic tropical cyclones undergo such a transformation at the end of their tropical existence. The metamorphosis typically starts as the system begins to be driven by atmospheric temperature differences rather than latent heat release. The cyclone begins losing its tropical characteristics and often develops front-like qualities. During the transformation the rain area usually shifts to the left of the storm track while the strongest winds diminish but become elongated to the right of the storm track. Some extratropical transition events can result in a more powerful storm than the originating tropical cyclone
