This paper focuses on the interactions between the fast solar wind from coronal holes and
the intervening slower solar wind, leading to the creation of stream interaction regions that …

Abstract Interplanetary Coronal Mass Ejections (ICMEs), their possible shocks and sheaths,
and co-rotating interaction regions (CIRs) are the primary large-scale heliospheric structures …

Space weather describes the way in which the Sun, and conditions in space more generally,
impact human activity and technology both in space and on the ground. It is now well …

In a previous study (Cane and Richardson, J. Geophys. Res. 108 (A4), SSH6-1, 2003), we
investigated the occurrence of interplanetary coronal mass ejections in the near-Earth solar …

We present the results of an investigation of the sequence of events from the Sun to the
Earth that ultimately led to the 88 major geomagnetic storms (defined by minimum Dst≤ …

We studied the geoeffectiveness, speed, solar source, and flare association of a set of 378
halo coronal mass ejections (CMEs) of cycle 23 (1996–2005, inclusive). We compiled the …

Using a classification of the near-Earth solar wind into three basic flow types:(1) High-speed
streams associated with coronal holes at the Sun;(2) Slow, interstream solar wind; and (3) …

We study the properties and geoeffectiveness of solar wind high‐speed streams (HSSs)
emanating from coronal holes and associated with stream interaction regions (SIRs). This …

In past studies, we classified the near-Earth solar wind into three basic flow types based on
inspection of solar wind plasma and magnetic field parameters in the OMNI database and …

The activity of the Sun alternates between a solar minimum and a solar maximum, the former
corresponding to a period of “quieter” status of the heliosphere. During solar minimum, it is …
