RADIATION BALANCE AND TURBULENT FLUX CHARACTERISTICS OVER MIZUHO STATION IN ANTARCTICA

In this paper,by using measurements in micrometeorology and radiation balance in the surface layer(Yamanouchiet al.,1981;Wada et al.,1981;Ishikawa et al.,1982;Ohata et al.,1983),we have analyzed the diurnal and annual varia-tion characteristics of radiation balance in spring,summer,autumn and winter,and calculated the momentum flux andsensible heat flux with the aerodynamic method and profile gradient alternate method in different seasons.We have alsoobtained the diurnal variation characters of the latent heat flux from the equation for energy balance.The results fromthe calculation are compared.Finally,the relationship between the turbulent heat and momentum exchange coefficientand the diurnal variation of the Richardson number is discussed.
