A survey of the non-radial flows (NRFs) during nearly five years ofinterplanetary observations revealed the average non-radial speed ofthe solar wind flows to be ~30km/s, with approximately one-half of the large (>100km/s)NRFs associated with ICMEs. Conversely, the average non-radial flowspeed upstream of all ICMEs is ~100km/s, with just over one-thirdpreceded by large NRFs. These upstream flow deflections are analysed in thecontext of the large-scale structure of the driving ICME. We chose 5magnetic clouds with relatively uncomplicated upstream flow deflections.Using variance analysis it was possible to infer the local axis orientation,and to qualitatively estimate the point of interception of the spacecraft withthe ICME. For all 5 events the observed upstream flows were in agreementwith the point of interception predicted by variance analysis. Thus weconclude that the upstream flow deflections in these events are in accordwith the current concept of the large-scale structure of an ICME: a curvedaxial loop connected to the Sun, bounded by a curved (though notnecessarily circular) cross section.  <b>Key words.</b> Interplanetary physics (flare and stream dynamics;interplanetary magnetic fields; interplanetary shocks
