内容記述 |
Acoustic sounding was used in observing a katabatic wind layer at the lowest few hundred meters over Mizuho Station (70°42′S, 44°20′E, 2230m above sea level), East Antarctica. Some examples of acoustic echo return showed the structure of surface inversions in connection with a katabatic wind and the behavior of breaking waves, e.g.a "herringbone" type structure described by EMMANUEL et al. (J. Atmos. Sci., 29,886,1972) as an unstable wave. Observations disclosed that wave-like motion exists in a layer between the heights of 100 and 300m and it has a shorter period than the calculated value from the Brunt-Vaisala frequency. This discrepancy was explained by a simple two-dimensional wave equation, considering the presence of mean atmospheric flow. |
