Sensible heat transfer across the wind-driven air-water interface in the high speed wind region with breaking wave was investigated through laboratory experiments in a wind-wave tank. We proposed the water vapor balance method for estimating the sensible heat transfer velocity in the high speed wind region with breaking wave, in stead of the heat balance method available only in the low speed wind region. The sensible heat transfer velocity monotonically increases with the free stream wind speed in the high wind speed region with breaking wave. The results suggest that the effect of breaking wave on the sensible heat transfer across the wind-driven air-water interface is small.
