CEDAR: Height-Resolved Joule Heating Rates and the Influence of Neutral Winds

研究人员正在测量高纬度E区焦耳加热率的垂直分布，以及E区中性风对这一分布的影响。 他的地址中性动力学，电动力学和能量在整个垂直列极E地区和耦合方面与磁层和低层大气。 他正在讨论的其他问题：（1）中性风上的洛伦兹力向下延伸到E区的程度;（2）地磁活动的水平及其持续时间如何影响焦耳加热率，解释中性风;（3）高纬度电离层的负载/发电机特性以及中性风对它们的影响;以及（4）增强的焦耳加热率与局部离子温度的相关性。 物理耦合发生在高纬度E和相互作用的潮汐强迫从下面，磁层从上面，到现在为止，知之甚少。 这项研究强调了焦耳加热率作为高纬度主要能源的重要性，将显著改变潮汐。

The investigator is measuring vertical distribution of the Joule heating rate in the high latitude E region, and the influence of E-region neutral winds on this distribution. He addresses neutral dynamics, electrodynamics, and energetics throughout the vertical column of polar E region and coupling aspects with the magnetosphere and lower atmosphere. Other issues he is hurdling: (1) to what degree the Lorentz force on neutral wind extends downward into the E region; (2) how the level of geomagnetic activity and its duration impacts the Joule heating rate, accounting for neutral winds; (3) what are load/generator characteristics of the high-latitude ionosphere and neutral winds' effect on them; and (4) the correlation of enhanced Joule heating rates with local ion temperature. The physical coupling occurring in high-latitude E and interplay of tidal forcing from below, magnetospheric from above, have, until now, been poorly understood. This study, highlighting the importance of the Joule heating rate as a primary high-latitude energy source, will change the tide significantly.
