Observations revealed, as to katabatic winds blowing above the two places, that the one above the latter is characterized by the presence of a hydraulic jump generated by nunataks there, resulting in a stronger turbulence than the one above the former which is stationary. Hence, a comparison is made in this paper between characteristics of turbulence and a hydraulic jump in a katabatic wind}, pages = {75--85}, title = {南極みずほ高原上の斜面滑降風の乱流(第1回南極気水圏シンポジウム)}, volume = {67}, year = {1979}, yomi = {コバヤシ, シュンイチ and イシダ, タモツ} }
