The characteristics of heat balance on the snow surface at Mizuho Station in Antarctica

In this paper, the data of the micrometeorology near the surface, the net radiation and the local pressure at Mizuho Station in Antarctica(1979) are analysed. The monthly average values of sensible and latent heat fluxes are calculated with Bowen ratio-energy budget method. The monthly average heat flux on the snow surface is studied. The heat budget on the snow surface is estimated directly using the net radiation flux. The obvious characteristic is that the value of the net radiation on the snow surface is negative from March to December. The supplement of the heat is obtained according to the sensible heat flux from the air to the snow surface. It can be concluded that the snow surface at Mizub(?) station is a strong cold source.
