标题： A Characteristic Signature of Magnetospheric Wave-Particle Interactions Found in the Turbulent E-region

摘要： 磁层中的电磁波散射电子，使其沉降到地球高层大气中，在那里将它们的时间特性赋予弥散极光。利用电离层E区的雷达观测和磁层的卫星观测，我们展示了磁层中增强的静电回旋谐波波活动与几秒后在附近磁场线的低层电离层中观测到的米尺度电离层等离子体湍流之间存在密切且前所未有的关联。 显示英文摘要

摘要： Electromagnetic waves in the magnetosphere scatter electrons, causing them to precipitate deep into Earth's atmosphere, where they impart their temporal characteristics to diffuse aurorae. Using radar-observations of the ionospheric E-region and satellite observations from the magnetosphere, we demonstrate a close and unprecedented association between enhanced electrostatic cyclotron harmonic wave activity in the magnetosphere and the appearance of meter-scale ionospheric plasma turbulence observed a few seconds later in the lower ionosphere on nearby magnetic field lines.
