Collaborative Research: Understanding the Asymmetric Thermospheric Response to Polar Driving

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。他的努力旨在更好地理解非线性耦合的热层和电离层是如何在极地风暴事件中不对称地驱动的，以及这些域之间的耦合如何影响整个系统级响应。该项目的目标是：a)利用新获得的南极数据，确定特定风暴期间南北半球的电动力驱动因素；b)研究半球不对称磁场结构如何控制系统级对强驱动的响应；c)研究半球不对称电离层和热层之间的能量和动量转移，以及这些过程如何影响不同驱动条件下的全球响应。d)了解极地热层背景和扰动中性风在不同驾驶条件下的不对称发展。随着空间气象目标的推进，研究生的培训为这项基于教育任务的研究提供了更广泛的影响。

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.
