ST2.4/PS5.2Terrestrial and planetary magnetotails and their response to variable upstream conditions (co-organized)
|Convener: Eija Tanskanen | Co-Conveners: Rumi Nakamura , Caitriona Jackman , Nicolas André
Examining the state of the magnetotail is crucial in understanding the magnetospheric dynamics in different time scales. Magnetotail lobes are known to be able to store magnetic energy and release it afterwards during magnetic storms and substorms. At times the magnetic energy is released in a steady mode and at times in a bursty mode, and the loading-unloading can be cyclic or non-cyclic. The different magnetotail responses may be produced by different interplanetary structures e.g. coronal mass ejections, interplanetary shocks or high-speed streams. We sough studies examining: how does tail lobes and plasma sheet response to the variable space weather conditions? When do we observe TCRs and plasmoids? What happens before, during and after the reconnection process? These questions can be addressed by multispacecraft observations from different magnetospheric locations and by ground-based instruments. We invite studies including observations, theory and modelling of magnetotail during variable space weather conditions. Multispacecraft analysis of Cluster and THEMIS are particularly welcome.
