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...

| Summary: | 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 direction to the sloped plane is zero (c) The wind vectors are uniform along the slope at each height (d) Monin-Obukhov's similarity theory is valid in each thin layer of Ekman layer (e) Local value of Monin-Obukhov length is defined by the local heat flux and the local momentum flux (f) New non-dimensional wind shear function (φ) is presented in neutial or stable Ekman laver, φ=(1+12 z/L)^<1/2> |
