Another goes through the central Gulf, and a third skirts the continental slope off Louisiana. These paths are caused by ring-slope interaction. Ring-slope interaction in this graveyard area can result in very strong offshore transport. Effects of atmospheric storms have also been captured in current meters. Hurricane effects in deepwater can be even more dramatic as in case of Hurricane Allen in 1980.
Cyclones also have an effect, giving rise to a characteristic current.
Cold air outbreaks are a third phenomena with three to four a month, fall through spring. These force inertial oscillations. These are diurnal and associated with the summer. For more information, contact Walter Johnson .
