The results are as follows： （a） The SWV is a kind of subtropical vortex, with characteristics of both an extratropical vortex and a tropical vortex. （b） In the case examined, large-scale circulation and other perturbation fields contributed to the formation and development of the SWV. （c） When the SWV moved from weak large-scale circulation EKE areas to strong ones, the EKE of the SWV increased, and vice versa. （d） Sub-grid processes and frictional dissipation were the main sinks of the SWV EKE, which contributed to the decay of the SWV. （e） The residual term （RES） and the Total （composite effect of all right hand side （rhs） terms except the RES in the EKE equation） varied almost in the same tendency, which kept the EKE varying in a moderate way. （f） The EKE between 550 hPa and 850 hPa increased most intensively, corresponding to the vertical stretching of the SWV.展开更多

The picking up of the second moment from echo spectra will make known more about atmospheric turbulence. It would be interesting to study the evolution of the mixed layers and gravity waves, etc. But the crosswind has a strong effect on the spectral width of back-scattered acoustic signals and the noise is another trouble. In this paper a method for better estimation of spectral parameters is described and the results prove to be meaningful.展开更多
