Self-Consistent Evolution of the Photoelectron-Driven Polar Wind from Ionospheric to Magnetospheric Altitudes Including the Effects of Wave-Particle Interactions

电离层和磁层耦合的主要机制之一是通过离子流出。 在白昼，极风的主要驱动力是光电子。 该项目将研究极地风的演变，使用混合模拟代码，可以考虑到光电子和波粒相互作用的碰撞效应。 由于来自磁层的粒子沉淀对极风的自洽效应也将包括在内。 理论和模拟工作的结果将与Akebono和POLAR卫星的数据进行比较。 这些结果将促进我们对电离层-磁层耦合的理解，这在磁层和空间天气的动力学中具有重要作用。

One of the major mechanisms for coupling the ionosphere and the magnetosphere is through ion outflows. On the dayside, the primary driver of the polar wind is photoelectrons. This project will investigate the evolution of the polar wind, using a hybrid simulation code that can take into account the collisional effects of the photoelectrons and wave-particle interactions. The self-consistent effects on the polar wind due to particle precipitation from the magnetosphere will also be included. The results from the theoretical and modeling work will be compared with data from the Akebono and POLAR satellites. The results will advance our understanding of ionosphere-magnetosphere coupling, which has an important role in the dynamics of the magnetosphere and space weather.
