Global Studies with Dual Schumann Resonance Methods

威廉姆斯/摘要本研究的目标是地球的行为，S自然地在三个不同的尺度上发生舒曼共振。在全球范围内，目标是了解背景舒曼共振强度的显著变化，以及这种变化如何受到对流层中与温度有关的条件不稳定的影响。在中尺度上，目标是了解与产生极低频Q爆发的高能正地面闪电有关的气象条件。我们现在能够从单站观测的全球基础上绘制这些事件的地图，这可能使研究中尺度对流系统的全球日变化成为可能。这种变化可能与全球电路的传统昼夜行为截然不同。在局部闪电尺度上，目标是了解与产生正地闪电有关的持续电流的性质和向地面的电荷转移。

Williams/Abstract The objectives of this research are the behavior of the Earth s naturally occurring Schumann resonances on three different scales. At a global scale, the objective is to understand the pronounced variability of background Schumann resonance intensity and how this variability is influenced by the temperature-related conditional instability in the troposphere. At the mesoscale, the objective is to understand the meteorological conditions associated with the production of energetic positive ground flashes that produce ELF Q-bursts. We are now able to map these events on a global basis from single-station observations and this may enable an investigation of the global diurnal variation of mescoscale convective systems. This variation may be quite distinct from the traditional diurnal behavior of the global circuit. At the local lightning scale, the objective is to understand the nature of the continuing current and the charge transfer to ground associated with the sprite-producing positive ground flashes.
