From dimensional considerations it is deduced that in wind–windsea equilibrium the fluid dynamical conditions can be described by only two nondimensional parameters. One is the wave age for the representative windsea. This describes the degree of windsea development relative to the local wind. The other is the windsea Reynolds number RB, which is defined by u 2 /νσp, where u∗ is the air friction velocity, ν is the air kinematic viscosity, and σp is the angular frequency at the windsea spectral peak. RBwas introduced by Toba and Koga in 1986, and formerly it was denoted as the breaking-wave parameter. It is the fundamental controlling parameter for the windsea boundary layer, and consequently for the behavior of air–sea transfers. RBis shown to be much superior to the 10-m wind speed, U10 or u∗, in studying the behavior of transfer coefficients. The air–sea CO2 transfer has traditionally been expressed in terms of a transfer velocity kLas a function of U10. We propose the use of a nondimensional transfer
