飞行路径方向的速度波动是通过安装在轻型飞机翼尖的单根热线测量的。随后通过标准方法分析磁带记录以产生一维光谱。这些光谱在数十个波数范围内表现出 (– 5/3) 幂律行为。通过进入并垂直于平均风的飞行路径在水平面上验证了局部各向同性。
Velocity fluctuations in the flight path direction were measured by a single hot-wire mounted in the wing tip of a light aircraft. Magnetic tape recordings were later analysed by standard means to produce one-dimensional spectra. These spectra exhibited the (– 5/3) power law behaviour over a range of several decades of wavenumber. Local isotropy was verified in the horizontal plane by flight paths into and perpendicular to the mean wind.
