Abstract:

The discovery of turbulent coherent structures is a major turning point in turbulence research. It is of great significance to understand the turbulence and the transport of matter, momentum and energy. In this paper, the discovery process was reviewed at first, and then the morphological characteristics, composition structure, flux contribution and other characteristics of turbulent coherent structure in atmospheric boundary layer were summarized, the causes were expounded, the typical formation mechanisms were explained, the application in practice was discussed, and the detection methods were summarized. Finally, the research trend in the future was prospected.

Key words: atmospheric boundary layer; turbulent coherent structure, characteristic, formation cause, application, detecting method
