英文摘要Based on the data from Zhongshan Station (eddy covariance measurements) and three Automatic Weather Stations deployed along the traverse route from Zhongshan Station to Dome-A, East Antarctica, and using aerodynamics method and eddy-correlation technique, we analyzed the seasonal and diurnal variation of the near surface turbulent parameters (sensible/latent heat fluxes, turbulent scales of temperature, specific humidity and wind speed, surface roughness length, atmospheric stability and momentum transfer coefficient), as well as their spatial distribution patterns. The results showed that sensible/latent heat fluxes display obvious annual variation and summer diurnal cycle. In summer, the near-surface air transfers heat to snow/ice in sensible heat flux form (except Dome A) and receives latent heat flux from snow/ice surface. Sensible (Latent) heat flux increases (decreases) with the increasing elevation and distance from the coast, from -4.2 (16.8) W/m(2) at Zhongshan to 5.5 (1.2) W/m(2) at Dome-A (the summit of the East Antarctic ice sheet). The spatial distribution patterns of surface roughness length, momentum transfer coefficient and friction velocity in summer are similar with wind speed, increasing southward from the East Antarctic coast into the interior escarpment region (strong katabatic wind zone), and then weakening gradually inland. It indicates that these surface dynamical parameters of the Antarctic ice sheet are closely related with wind speed. The results have an important reference value on improving the boundary layer parameterization scheme in Antarctic climate simulation.
