CAREER: Transport of Ions and Electrons in Solar Energetic Particle Events -- Towards an Integrated Space Weather Model

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。在这个项目中，首席研究员（PI）将对太阳高能粒子（SEP）事件中的电子和离子传递进行系统研究，并为空间物理学家制定培训计划。PI将开发一种增强的蒙特卡罗方法，通过跟踪单个粒子的轨迹来跟踪高能粒子的传播；研究太阳风磁流体动力学（MHD）湍流的径向依赖性如何影响高能粒子输运；探索超越静态准线性理论的太阳风MHD湍流的各种动态近似；并研究太阳风中的通量管对高能粒子输运的影响。该项目将包括设计和开发一门由PI教授的新的空间物理课程，以改进阿拉巴马大学亨茨维尔分校物理系的空间物理课程。PI的科学调查将导致一个有充分记录的模型，这将为研究SEP事件中的粒子输运提供一个现实的数值工具。由于SEP事件是一种严重的空间天气危害，因此该模型对实际空间天气预报非常有用。研究sep的输运及其与日球层行星际等离子体的相互作用将直接有助于增加对宇宙中高能粒子输运的理解。该项目的教育和培训部分将直接支持两名研究生和几名本科生。除了在UAH开发课程外，PI还将组织一次两年一次的研讨会，讨论空间天气研究的最新进展，以补充一年一度的SHINE（太阳、日球层和行星际环境）会议。PI将为全国各地申请参加他的研讨会的感兴趣的研究生提供经济支持。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).In this project, the Principal Investigator (PI) will perform a systematic study of electron and ion transport in solar energetic particle (SEP) events and create a training program for space physicists. The PI will develop an enhanced Monte Carlo approach to follow the propagation of energetic particles by tracing single particle trajectories; examine how the radial dependence of solar wind magnetohydrodynamics (MHD) turbulence can affect energetic particle transport; explore various dynamic approximations of solar wind MHD turbulence beyond static quasi-linear theory; and investigate the effects of flux tubes in the solar wind on the transport of energetic particles. This project will include the design and development of a new space physics course to be taught by the PI, improving the space physics curriculum in the Physics Department at the University of Alabama at Huntsville (UAH).The PI's science investigation will lead to a well documented model which will provide a realistic numerical tool to the community for studying particle transport in SEP events. This model will be useful for operational space weather forecasting, since SEP events are a serious space weather hazard. Studying the transport of SEPs and their interaction with interplanetary plasma in the heliosphere will directly contribute to increased understanding of energetic particle transport in the cosmos. The project's education and training component will directly support two graduate students and several undergraduate students. In addition to curriculum development at UAH, the PI will organize a biannual workshop on recent progress in space weather studies to complement the annual SHINE (Solar, Heliospheric, and INterplanetary Environment) meeting. The PI will provide financial support to interested graduate students throughout the country who apply to attend his workshop.
