本文利用多航天器观测资料研究了地球磁层边界层中引起的涡旋湍流的性质,以期揭示无碰撞太阳风等离子体向磁层中传输的机制。已建立的方法,从现场测量的Kelvin-Helmholtz涡发展到非线性阶段的识别,并已获得有关的激励和非线性演化的涡及其后果的新见解。漩涡可能不是太阳风进入的主要参与者。
英文摘要
The nature of eddy turbulence induced in Earth's magnetospheric boundary layer is examined by using data from multi-spacecraft measurements, with a view to revealing the mechanism by which collisionless solar wind plasma is transported into the magnetosphere. The methods have been established for identification from in situ measurements of Kelvin-Helmholtz vortices developed to the nonlinear phase, and new insights have been obtained regarding the excitation and nonlinear evolution of the vortices and their consequences. The vortices may not be the major player in the solar wind entry itself.
