Foreshock Transients and their Impacts on the Bow Shock/Magnetosheath/Magnetosphere System

Session ID#: 161570

Session Description:
Spacecraft observations show that there are a wide variety of foreshock transient events. When these transients interact with the bow shock/magnetosheath/magnetosphere system, there is a transfer of energy and momentum. This session will focus on observational and theoretical studies of foreshock bubbles, hot flow anomalies, spontaneous hot flow anomalies, flux transfer events, magnetic impulse events, traveling convection vortices, convection flow channels, pressure pulses and dayside ionospheric events. The emphasis here is on identifying the mechanisms driving the events and establishing their significance via studies combining observations from muti-spacecraft and ground-based instruments within the context of results from theoretical models and computer simulations.
