Abstract:

This paper deals with some characteristics for the atmospheric boundary layer structure and the transfer of the turbulent fluxes over the Zhongshan Station area. The data of temperature,humidity,wind and pressure profiles were collected by using TMT (tethersonde meteorological tower)sounding system at this area in the period of summer expedition, 1994-1995. The fluxes of momentum and sensible heat were evaluated by semiemperical flux profile relation of Monin Obukhov similarity theory from these observed data . The results show that the characteristics of atmospheric boundary layer structure and the transfer of turbulent fluxes have obvious differences for different stations ( Zhongshan Station, the Ice Sheet Camp and the Sea Ice Camp). Therefore they are very complicated and have strongly local property in Antarctica.
