摘　　要：文章利用2020年8月满洲里西郊机场风廓线雷达数据,对湍流耗散率ε进行了计算,针对满洲里典型天气条件下的湍流耗散率ε、折射率结构常数C^(2)_(n)、水平风速、垂直风速等进行了分析。得出了大气湍流耗散率ε的变化范围;湍流耗散率ε具有较为明显的时空分布特征;风廓线计算得到的湍流耗散率ε与机载QAR记录的数据结果一致性等结论,为风廓线雷达湍流探测应用提供了参考。Based on the wind profile radar data of Manzhouli west suburban airport in August 2020,this paper calculates the turbulent dissipation rateε.The turbulent dissipation rateε,refractive index structure constant C^(2)_(n),horizontal wind speed and vertical wind speed under typical weather conditions in Manzhouli are analyzed.The variation range of atmospheric turbulence dissipation rateεis obtained.The turbulent dissipation rateεhas obvious spatial and temporal distribution characteristics.The turbulence dissipation rateεcalculated by wind profile is consistent with the data recorded by airborne QAR,which could provide a reference for the application of wind profile radar turbulence detection.
