Numerical Simulation of Katabatic Wind Profile at Syowa Station, Antarctica (Special Issue of the Proceedings of the First Symposium on Antarctic Meteorology and Glaciology)

The vertical profiles of the strong katabatic winds at Syowa Station, Antarctica, are studied. A numerical solution of the equations of the Ekman layer above the Antarctic coastal slope is obtained under the following assumptions, (a) The steady state condition (b) The wind component of normal direc...
