The specific heat of seawater is about 4.2 x 103 J/(kg*K), while the latent heat of vaporization (or evaporation) is about2.5 x 106 J/Kg. What do these figures including theirunits express? In the suptropics, the latent heat flux across thesea surface is typically -125 W/m2. How many meters ofwater column per year would need to be evaporated to match thisfigure?
