Characteristics of Tropical Cyclone Outer Size and Structure Associated With Extratropical Transition

Geophysical Research Letters
There is a lack of consensus on how tropical cyclone outer winds may change, if at all, due to extratropical transition. Hence, this study examines changes in North Atlantic tropical cyclone outer size and structure using a large, multidecadal sample of ...
