Centennial evolution of monthly solar wind speeds: Fastest monthly solar wind speeds from long-duration coronal holes
Renata Lukianova, Lauri Holappa, Kalevi Mursula
High speed solar wind streams (HSSs) are very efficient drivers of geomagnetic activity at high latitudes. In this paper we use a recently developed parameter of geomagnetic…
Seasonal solar wind speeds for the last 100 years: Unique coronal hole structures during the peak and demise of the Grand Modern Maximum
Kalevi Mursula, Lauri Holappa, Renata Lukianova
Solar coronal holes are sources of high-speed solar wind streams, which cause persistent geomagnetic activity especially at high latitudes. Here we estimate seasonal solar wind spe…
Occurrence of high-speed solar wind streams over the Grand Modern Maximum
Kalevi Mursula, Renata Lukianova, Lauri Holappa
In the declining phase of the solar cycle, when the new-polarity fields of the solar poles are strengthened by the transport of same-signed magnetic flux from lower latitudes, the…
