Collaborative Research: Understanding the Asymmetric Thermospheric Response to Polar Driving

该奖项由2009年美国复苏和再投资法案(公法111-5)资助。他的努力旨在更好地理解极地风暴事件中非线性耦合的热层和电离层是如何不对称地驱动的，以及这些领域之间的耦合如何影响整个系统级的响应。该项目的目标是：a)利用最新获得的南极数据，确定特定风暴期间南北半球的电动驱动因素；b)调查半球不对称磁场配置如何控制系统一级对强驱动的反应；c)研究电离层和热层之间的半球非对称能量和动量转移，以及这些过程如何影响全球对不同驱动条件的反应；d)了解极地热层背景和扰动中性风在不同驱动条件下如何不对称地发展。随着空间气象目标的推进，对研究生的培训为这项拟议的研究提供了更广泛的影响，这一努力以教育任务为基础。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).his effort seeks to develop a better understanding of how the nonlinearly coupled thermosphere and ionosphere are driven asymmetrically in polar storm events, and how coupling between these domains affects overall system-level response. Goals of the project are to a) specify electrodynamic drivers in the northern and southern hemispheres during specific storms with newly available Antarctic data, b) investigate how the hemispherically asymmetric magnetic field configuration controls system-level response to strong driving, c) examine the hemispheric asymmetric energy and momentum transfer between the ionosphere and thermosphere and how these processes affect the global response to different driving conditions, and d) understand how the polar thermospheric background and disturbance neutral winds asymmetrically develop under different driving conditions. Along with furtherance of space-weather objectives, the training of graduate students provides the broader impact to this proposed research grounding this effort in an educational mission.
