湍流介质中的猝发现象和光传输
Bursts in the Turbulent Medium and Light Propagation
摘要
大气中的测量结果表明,不稳定的层结湍流介质中,可能频繁出现带温度突变面的涡漩,由于其结构的不对称性,能够导致介质的某些光传输特性偏离湍流均匀各向同性理论.温度突变面的产生可能和层结湍流介质中涡漩在竖直方向的移动有关,我们把这种涡漩的产生和移动叫做"猝发”(burst).
Abstract
It is shown by the results measured in the atmosphere that the eddies with temperature sharp Changing section via temperature discontinuous surface may frequently occur in an unstable stratified turbulent medium. Because the structure of temperature discontinuous surface is very asymmetrical,the properties of light propagation of turbulent medium would departure the theory of isotropic turbulence. The occurring of discontinuous surface is probably related with the removing of eddies in the vertical direction in the stratified turbulent medium. The production and removing of these eddies can be named " burst".
