|
摘要
为探索反演湍流耗散率的最优方法,促进湍流规律和机理研究以及相关方法的业务化应用,文章根据风廓线雷达和无线电-声探测系统的探测原理,选取实例数据,通过虚温计算的布维频率和大气湍流引起的谱宽反演湍流耗散率。研究结果表明:该方法较为有效和简便,适用于加装无线电-声探测系统的风廓线雷达;湍流耗散率并不完全随高度增加而递减,而存在某高度层内湍流较强的现象;湍流耗散率与大气稳定度相互影响。
In order to explore the optimum method for retrieving turbulent dissipation rate,to promote the study of turbulence law and mechanism,to make the application of related methods in business,the sample data were selected,the turbulent dissipation rate was inverted through the Brunt-Vaisala Frequency calculated by imaginary temperature and the spectral width caused by atmospheric turbulence,based on the detection principle of wind profiler radar and Radio-Acoustic detection system.The results showed that the method was effective and simple,and was suitable for wind profiler radar equipped with Radio-Acoustic detection system.Turbulence dissipation rate did not decrease completely with the increase of altitude,but there was strong turbulence in a certain altitude layer.Turbulence dissipation rate and atmospheric stability interact.
