Abstract
The contribution of bubbles to the air-ocean heat exchange during passages of extreme typhoons was investigated based on a field observation at the ocean. We proposed an ultrasonic backscatter model estimating bubble population and heat flux through the bubble interface. Bubbles produced in an extreme weather were found to be entrained to an ocean surface layer to rapidly exchange heat with the sea water, resulting in vertical transfer of heat in the ocean.
