The strongest magnetospheric disturbances are caused by <\/span><span style=\"font-family: verdana, geneva, sans-serif\">interplanetary coronal mass ejections (ICMEs) and their embedded magnetic fields, which can often be <\/span><span style=\"font-family: verdana, geneva, sans-serif\">described as magnetic flux ropes (MFRs). In many cases, it is not fully clear what IMF features lead to the <\/span><span style=\"font-family: verdana, geneva, sans-serif\">largest disturbances in the magnetosphere. Is the most crucial the duration of the negative Bz interval, the <\/span><span style=\"font-family: verdana, geneva, sans-serif\">minimum Bz, or some integrated electric field that characterizes the solar wind energy flux? Which magnetic <\/span><span style=\"font-family: verdana, geneva, sans-serif\">structures are more geoeffective: The highly fluctuating ones, where large negative Bz alternates with positive <\/span><span style=\"font-family: verdana, geneva, sans-serif\">Bz, or sustained intervals with moderately negative Bz?<\/span><\/p>\n<p><span style=\"font-family: verdana, geneva, sans-serif\">We will use solar wind and ICME models to simulate different IMF structures.

In this <\/span><span style=\"font-family: verdana, geneva, sans-serif\">way, we can study the response of the magnetosphere to different IMF configurations.
