Triggered Large-scale Auroral Disturbances and PBIs: Polar Ionospheric Convection Evolution and Structure

[06:11 . 17]里昂摘要这是一个为期两年的奖项，旨在继续努力记录和了解不同类型的极光干扰的原因。该项目的最终目标是建立太阳风与行星际磁场的变化之间的关系，与重联有关的电离层流在白天的变化，以及由此产生的极光干扰类型。了解这些关系对于改善极光干扰的规范和预测至关重要，极光干扰可能导致无线电传输和卫星通信的中断，包括全球定位系统。该项目的主要目标是根据最近对极地观测技术的投资，推导和验证观测技术，以确定各种极光干扰。具体的重点是确定哈朗不连续的夜侧电场反转。研究工作将主要由研究生进行。

The project relates to the ultimate goal of establishing the relationships between changes in the solar wind and interplanetary magnetic field, changes in the reconnection related ionospheric flows on the dayside, and the resulting types of auroral disturbances. Understanding these relationships is essential to improve specification and forecasting of the auroral disturbances, which can cause disruption of radio transmission and satellite communications, including the Global Positioning System. The main objective of the project is to derive and verify observational techniques based on recent investments in polar observation technology to identify the various auroral disturbances. Specific focus is on the determination of the nightside electric field reversal in the Harang discontinuity. The research work will be carried out mainly by graduate students.
