Working Group 3

Simulation group led by Dusan Odstrcil (USA) and Fang Shen (China); At-large leaders: Noe Lugaz (USA) and Chin-Chun Wu (USA)

Scientific Objective

• Provide global context for all CME events investigated by the ISEST team
• Investigate processes of the CME initiation and heliospheric propagation

• Develop tools to assist collaboration of numerical modelers, theoreticians, and observers

Scientific Questions

• Initiation
• Propagation
• Impact

Simulations, Data, Results

Event Periods (with WG1)

• late July to early August 2010
• February 2011
• early March 2012
• July 2012

Mechanisms, processes, and forces (with WG2)

• How much variable ambient conditions affect ICMEs?
• Which mechanisms, processes, forces are governing the CME take-off and ICME propagation?
• The CME-associated phenomena

Forecasting the CME arrival and impacy (with WG4)

• Arrival time
• Geo-effectiveness
• Energetic particles
