• Micrometeorological conditions were observed over fast ice with overlying thick snow cover and underlying deep sea approximately in the center of Ongul Strait in Lutzow-Holm Bay, Antarctica, from the end of March to the beginning of December in 1990. In response to the annual change of solar radiation, the radiation balance had an annual change; the radiation balance was negative for a period including the polar night, and changed to positive after October. Corresponding to the radiation balance, both the sensible heat flux from the air to the snow and the conductive heat flux from the fast ice to the snow changed. Especially, the sensible heat flux changed with the radiation balance like a mirror image. As the prevailing wind velocity increased, the temperature and humidity increased, and the radiative heat loss, the sensible heat flux from the air to the snow, and the conductive heat flow from the fast ice to the snow decreased.
