Linear and Nonlinear Plasma Waves Generated by the Earth's Bow Shock

这项研究提供了当前项目的延续，包括对地球弓形激波附近等离子体波的理论和观测研究。会议将讨论四个主要议题。这包括(1)阿尔芬波的理论研究；(2)前震观测资料分析；(3)继续利用线性分析技术研究电子束的不稳定性；(4)利用数值计算机技术模拟电子束不稳定性。这项研究将涉及阿尔文波和朗缪尔波，这两种波都存在于这部分空间。研究太阳风与地球环境的波和粒子相互作用，对于进一步了解地球大气结构与太阳变率之间的各种耦合过程至关重要。* * * / /

This research provides a continuation of the current program involving theoretical and observational studies of plasma waves in the vicinty of the Earth's bow shock. Four major topics will be addressed. These include (1) theretical studies of Alfven waves; (2) analysis of observations in the foreshock; (3) continuation of studies relating to electron beam instabilities using linear analytical techniques; and (4) electron beam instability simulations using numerical computer techniques. The research will address both Alfven and Langmuir waves, both of which are known to exist in this part of space. Studies of the of the wave and particle interaction of the solar wind with the Earth environment are essential to futher our understanding of the various coupoling processes tying the Earth's atmospheric structure to solar variability. *** //
