NSWP: Determining the Relationships between Promptly Penetrating, Daytime Low Latitude Electric Fields and Interplanetary Electric and Magnetic Field Conditions

本文半经验地模拟了由地球磁场和电离层电场（ExB）的相对方向和强度驱动的等离子体垂直漂移，以及这些漂移对行星际磁场（IMF）的敏感性。将多元回归和神经网络分析应用于来自秘鲁Jicamarca雷达站点的非相干散射雷达（ISR）数据、来自Jicamarca的低功率JULIA雷达数据、来自秘鲁和菲律宾站点的磁力计数据以及ACE卫星数据，以提高我们对穿透电场的理解。Rice对流模型也被用于提供物理驱动的理论见解，通过耦合到电离层电场，将IMF耦合到垂直离子漂移。研究的重点是更准确地描述白天迅速穿透的电场与行星际电场和磁场条件之间的时间依赖关系。同时，确定了IMF驱动电场的纵向变化。

Vertical Plasma drifts driven by the relative orientation and strengths of the Earth's magnetic field and ionospheric electric fields (ExB), and the sensitivity of those drifts to the interplanetary magnetic field (IMF) are modeled semi-empirically. Multiple-regression and neural network analyses are applied to incoherent scatter radar (ISR) data from the Jicamarca, Peru radar site, to low power JULIA radar data from Jicamarca, to magnetometer data from Peru and from the sites in the Philippines, and to ACE satellite data to improve our understanding of penetrating electric fields. The Rice Convection Model is also used to provide theoretical insight into physical drivers that couple the IMF to vertical ion drifts through coupling to ionospheric electric fields. The research focuses on more accurate descriptions of the time dependant relationships between promptly penetrating electric fields in the daytime and the interplanetary electric and magnetic field conditions. Also, the longitudinal variation of IMF driven electric fields is determined.
