Observations and model circulations of aerodynamic drag on sea ice in the Fram Strait
Wind and temperature profiles in the constant flux layer, obtained by tethersonde, were used to compute the total aerodynamic drag on an area of 60% pack ice in the Fram Strait (79 degrees 20'N, 1-3 degrees W). The boundary layer appeared adiabatic to heights >150 m, and there were only mino...

| Zusammenfassung: | Wind and temperature profiles in the constant flux layer, obtained by tethersonde, were used to compute the total aerodynamic drag on an area of 60% pack ice in the Fram Strait (79 degrees 20'N, 1-3 degrees W). The boundary layer appeared adiabatic to heights >150 m, and there were only minor air-water temperature differences. Drag coefficients of 4.9 and 5.1 x 10 super(-) super(3) referred to 10 m a.g.l. were found. Eddy correlation measurements in the local constant flux layers over ice floes were used to estimate the skin drag of an area of 100% ice cover. This was |
