摘要
利用１９８９年１２月～１９９０年１月重庆地区的观测资料，计算了一般天气条件下和雾中的湍流谱。结果表明，重庆地区在中性和不稳定的条件下，湍谱的峰值频率比平坦地形大，峰值区较窄。在夜间静力稳定条件下，湍谱的低频部分能量突然增大。
Turbulence spectra are investigaed that result in the presence of fog and otherwise using Chongqing wind record from December 1989 to January 1990. Results show that under neutral and unstable stratification the frequency of peaks is higher in this hilly area as compared to the plains, with a narrower domain of the peaks; under nighttime hydrostatic stability, the energy increases sharply in the low frequency portion. Besides, case studies exhibit significant features of such spectra on a foggy day.
