Abstract in another language

Detailed analyses of air temperature profiles measured over the Antarctic shelf ice revealed the frequent presence of an inversion layer in the lower 2 m above ground. The regular character of the phenomenon allowed for an in-depth description of its diurnal evolution and long-term behavior. From additional high-resolution temperature profile measurements it was observed that the inversion layer leads to a decoupling of the surface layer heat fluxes from the radiative surface temperature. It is demonstrated that bulk parameterizations are not able to provide valid predictions of turbulent heat fluxes under such conditions. A model with a three-layer temperature profile is shown to give useful estimates for the aerodynamic temperature, even in the presence of an inversion layer near the surface. This indicates a possible approach to address the limitations of current bulk parameterizations for heat fluxes in high latitudes.
