Some Features of the Turbulent Transfer on the Bare Ice Field Near the Yamato Mountains, East Antarctica
Measurements were made of profiles of wind speed and air temperature on the bare ice surface on the lee of the Yamato Mountains from 1 to 7 December 1973. The vertical profile of air temperature was found unstable in the daytime when the wind speed decreased, as the bare ice surface was heated by so...

Consequently, a mean eddy heat flux transported from the surface was 50ly/day.
