“…Some results of the horizontally two-dimensional structure (e.g., Panofsky, 1962;Ropelewski et al, 1973;Shiotani and Iwatani, 1976;Shiotani et al, 1978;Naito, 1982) were estimated from observations along a line perpendicular to the wind direction, using Taylor's frozen eddy hypothesis (Taylor, 1938).
