Transfer of energy between ocean and atmosphere in the form of sensible heat flux is due to
Answer: B
Sensible heat flux is due to the difference in temperature between the upper surface of the ocean and the lower part of the atmosphere.
Sensible heat is exchanged by conduction and turbulent transfer whenever the sea surface and the air above it are at different temperatures; bulk formulas take it proportional to the wind speed times the air-sea temperature difference.
A difference in specific humidity drives the latent heat flux (evaporation), a difference in CO2 partial pressure drives the gas flux, and a density difference does not drive heat exchange.
