Study on the Hydrothermal Exchange of Underlaying Surface in the Moving Dune of Inner-Mongolia

CHEN Min-yan et al(Department of Atmospheric Sciences,School of Physics,Peking University,Beijing 100871)  
Utilizing the test data of atmospheric boundary layer in the moving dune of Inner-Mongolia in the summer of 2001,the paper calculated the turbulent flux including the momentum and sensible heat flux by the aerodynamics method and eddy covariance method,analyzing the effects of nonuniform underlaying surface and temperature profile structure on turbulent flux and adaptability of flux-gradient relationship,and compared with results of acquiring turbulent flux by aerodynamics method and eddy covariance method.Meanwhile,combined with the terrain and climatic characteristics of moving and sufficient water content,discussing the acquiring method of turbulent under the nonuniform underlaying surface.
