Using the observation data from Longbao, Yushu of Qinghai Province, daily variations of momentum flux and sensible heat flux during unfrozen, frozen and frozen with snow covered periods are analyzed, momentum bulk transfer coefficient, sensible heat bulk transfer coefficient, aerodynamic roughness length, thermal roughness length are calculated, relationship between additional damping and roughness reynolds number are analyzed and three kB-1 parameterization schemes are compared. The results show that daily ranges of momentum flux and sensible heat flux are the biggest in frozen period and the smallest in frozen with snow covered period. Momentum bulk transfer coefficient CD and sensible heat bulk transfer coefficient CH are the biggest in frozen period and the smallest in frozen with snow covered period. Aerodynamic roughness length and thermal roughness length are the smallest in frozen period and the biggest in frozen with snow covered period. Power function type of three kB-1 parameterization schemes is the most suitable during unfrozen, frozen, and frozen with snow covered periods.
