摘　　要：本文根据南沙群岛渚碧礁的一次大气湍流观测资料，分析研究南沙海域的湍流热通量输送、方差相似性、风速各分量谱、温度谱及各湍流通量协谱等大气湍流结构和输送特征，并与陆地下垫面上的结果作了比较。With the data observed in Nansha Islands, the characteristics of the both transfer and atmospheric turbulence structure of some physical parameters in the boundary layer are analyzed in this paper. These parameters include heat fluxes, variation similarity, wind spectrum (u,v,w), temperature spectrum and cospectrum of different turbulent fluxes in the Nansha Islands area. Furthermore, these analyzed results are compared with the results in the land surface and some new ideas about the characteristics of the atmospheric turbulence structure and transfer in the Nansha Sea region are obtained.
