Re: Tropics Acting Up Again

I know this doesn't have anything to do with the center being exposed but w/ 95L lost/decrease in convection have to do with it making the transition from low attached to a front to a tropical low? Lows that transition from cold to warm core as they do change do they loose convection and refire it again once they become warm core and feed off of the ocean water? (sorry hope my question is understandable and not wordy or confusing).
Nah, and in fact it is usually the persistence of convection that signifies a system undergoing transition to a warm-core entity; it suggests that the ingredients are in place for a tropical system to survive and helps build the mechanisms by which oceanic warmth can be carried to the upper levels.
Sometimes you'll see tropical disturbances in the deep tropics build convection, have it die out, and then build it again and develop -- but it's somewhat different than what we're looking at here (even though it does help erode the very weak cold core believed to be associated with tropical waves) as it relates more to the development of a vortex than the transition of a pre-existing vortex.
