摘要

We have achieved all the goals stated in our grant proposal. Specifically, these include: (1) The understanding of the complexity induced nonlinear spatiotemporal coherent structures and the coexisting propagating modes; (2) The understanding of the intermittent turbulence and energization process of the observed Bursty Bulk Flows (BBF's) in the Earth s magnetotail; (3) The development of 'anisotropic three-dimensional complexity' in the plasma sheet due to localized merging and interactions of the magnetic coherent structures; (4) The study of fluctuation-induced nonlinear instabilities and their role in the reconfiguration of magnetic topologies in the magnetotail based on the concepts of the dynamic renormalization group; (5) The acceleration of ions due to the intermittent turbulence of propagating and nonpropagating fluctuations. In the following, we include lists of our published papers, invited talks, and professional activities. A detailed description of our accomplished research results is given.
