Ocean Weather Ship Papa

This scenario is a classical scenario for the Northern Pacific, for which long term observations of meteorological parameters and temperature profiles are available. The station Papa at 145$ ^{\circ}$W, 50$ ^{\circ}$N has the advantage that it is situated in a region where the horizontal advection of heat and salt is assumed to be small. Various authors used these data for validating turbulence closure schemes (Denman (1973), Martin (1985), Gaspar et al. (1990), Large et al. (1994), Kantha and Clayson (1994), d'Alessio et al. (1998), Burchard et al. (1999), Villarreal (2000), Axell and Liungman (2001), Burchard and Bolding (2001)).

The way how bulk formulae for the surface momentum and heat fluxes have been used here is discussed in detail in Burchard et al. (1999).

For mixing below the thermocline, an internal wave and shear instability parameterisation as suggested by Large et al. (1994) has been used. The maximum simulation time allowed by the included surface forcing file and the temperature profile file is January 1 (17.00 h), 1960 - December 31 (12.00 h), 1968. In this scenario, the simulation time is run from March 25, 1961 (0.00 h) to March 25, 1962 (0.00 h).

This scenario has been discussed in detail by Burchard et al. (1999). We are grateful to Paul Martin for providing the meteorological data and the temperature profiles, see also Martin (1985).
