The poleward movement of a decaying
tropical cyclone often results in a rapidly-moving,
explosively-deepening midlatitude cyclone. The
re-intensification of the remnant tropical cyclone
as an extratropical cyclone depends on the
phasing between the decaying tropical cyclone
and a midlatitude environment that is favorable
for midlatitude cyclogenesis (Klein et al. 2001).
Because of the typical rapid translation speed
(Jones et al. 2003) of the decaying tropical
cyclone, accurate extended-range prediction of
the phasing between the remnant tropical
circulation and the midlatitude environment into
which it is moving is critical.This research has been supported by the Office of Naval Research, Marine Meteorology
