Abstract
Recently Maki (1974) reported the observations of the atmospheric turbulence above the sloping surface at Syowa Station in Antarctica in 1970 by means of an ultra sonic anemometer which was mounted at the 20m level of a meteorological tower (21m height). He shows that the turbulent intensities (σu/u*, σν/u* and σω/u*) are almost independent of Ri in stable conditions, and their averaged values are 1.80, 1.55 and 3.00, respectively, where σu, σν and σω are the standard deviations of the wind fluctuation in longitudinal, lateral and vertical directions, respectively, and u* is the friction velocity. And he also shows that the mean wind vector has an inclination of 18°16' (tan-1 0.330) from the horizontal plane, (the broken line of Fig. 2 in this paper.)
The present author has made the observations of wind and temperature fluctuations at the same tower of the same place in 1971. The results of the observation do not always coincide with Maki's results. The following are the summary of the present results (Adachi, 1973).
