2. Page 2HMI Team Meeting – January 26-27, 2005 HMI science objectives are grouped into five broad categories: Convection-zone dynamics and the solar dynamo; How does the solar cycle work? Origin and evolution of sunspots, active regions and complexes of activity; What drives the evolution of spots and active regions? Sources and drivers of solar activity and disturbances; How and why is magnetic complexity expressed as activity? Links between the internal processes and dynamics of the corona and heliosphere; What are the large scale links between the important domains? Precursors of solar disturbances for space-weather forecasts. What are the prospects for predictions? These objectives are divided into 18 sub-objectives each of which needs data from multiple HMI data products. HMI Science Objectives – Top Level
