Abstract
Based on the ultrasonic anemometer/thermometer data in the East Antarc tic coastal area ice sheets obtained first by Chinese scientists, turb ulent intensity, kinetic energy and sensible heat of turbulence, surfa ce; roughness height drag coefficient and normalized variation were ca lculated and analysed using the eddy-correlation method. The results s how that the values of roughness height and drag coefficient are 4.3 x 10(-4) m and 1.8 x 10(-3), respectively. These turbulent parameters h ave apparent diurnal variations.
