吾人利用超音波測風儀以10赫之取樣率在海研一號船上及臺中港海邊實地觀測海面邊界層內空氣之亂流運動,即使儀器受到船體運動的影響,10赫取樣率仍可鑑別出亂流能譜中的慣性領域。超音波儀器在雨中對亂流運動仍然保持良好反應,雨中亂流運動的能譜顯示在慣性領域依然滿足-5/3定律,但是能量會減少,水平擾動仍保有無向性,但是垂直擾動明顯偏離無向性,吾人可利用能講慣性消散法來推算亂流應力大小,這樣可避開對儀器方向性敏感的困難,但在應用此方法時必需先扣除亂流場不均勻特性及對流所造成的影響。
Surface layer turbulence has been observed with an ultrasonic anemometer aboard a research vessel and at Taichung harbour. The 10 Hz sampling rate provides sufficient resolution to give the equilibrium spectrum at the inertial subrange even when the instrument is mounted on a ship. The sonic anemometer responses well during rain fall, however, the energy level within the inertial subrange decreases. The dissipation method can be used to calculate the turbulent stress to avoid the problem of sensitivity to instrument orientation, but the correction of the bouyant flux and the flow inhomogenity have to be considered.
