Analysis of Turbulent Characteristics and Spectrum during the Cold Wave
寒潮冷锋过境期间湍流特征量及其谱分析

Based upon the data of three orthogonal wind velocity components and temperature withtwo ultrasonic anemometer / thermometers at the height of 47 m and 120 m of the IAP MeteorologicalTower, this paper calculates and analyses the diurnal variations of turbulent characteristics and thenormalized spectrum of the wind velocity components and temperature during the cold front weather.They play specified large-scale turbulence characteristics.
