Abstract

Data obtained during Ulysses' rapid northbound traverse across the heliographic equator provide evidence for predicted, opposed north‐south tilts of corotating interaction regions formed from streams originating in the northern and southern solar hemispheres respectively. In both hemispheres, reverse waves that were propagating poleward were observed poleward of the latitudes where the fast‐slow wind interaction occurred. Forward waves, on the other hand, were observed only within the low‐latitude band of wind variability, consistent with the prediction of systematic, opposed tilts. However, the evidence for opposed north‐south tilts within the low‐latitude band of variability was less conclusive.
