Webusing a generalization of the Charnock (1955) formula to include low-wind conditions: With ν the kinematic viscosity, u* the friction velocity, α the Charnock coefficient (set to a constant value) and g the gravity acceleration. In ACCESS1.3, a new expression of the Charnock coefficient was constructed to take into account its WebOne common method of coupling developing waves and stress is to make the Charnock coefficient α ch explicitly dependent on the sea state by computing it either in the wave model from the wave spectra (e.g. Janssen et al., 2001) or in the atmospheric model as a function of the wave age (Mahrt et al., 2001; Oost et al., 2002; Moon et al., 2004). bournemouth symphony chichester 7 july
