南京市近地层湍流结构及输送特征研究
A STUDY OF TURBULENCE STRUCTURE AND TURBULENCE TRANSFER CHARACTERISTIC IN THE SURFACE-LAYER AT NANJING CITY
【摘要】 本文利用“城市生物气溶胶研究”中的超声风温仪观测资料,对南京市近地层大气的湍流强度、相关系数、速度谱及通量输送等进行研究,得到南京市近地层湍流结构及输送特征的一些结论。
【Abstract】 In this paper,the data got by the ultra-sonic anemometer in the program of "Experimental Study on the Bioaerosols Pollution and its Transport,Decay and Deposition in the Cties" are analyzed. Some results are gained,included the turbulence structure and characteristic in the surface-layer at Nanjing City,such as the turbulence intensity, the turbulence autocorrelation coefficient,turbulence energy spectra and the turbulence transfer characterlstic.
