Observations of the Stationary Katabatic Winds in Mizuho Plateau, East Antarctica
This paper describes the study on the thickness and intensities of surface inversions and vertical wind profiles in a katabatic wind layer existing semipermanently in the Mizuho Plateau. Observations of vertical temperature and wind profiles in lower layer were carried out ten times by means of radi...
