Assessing North Atlantic winter climate response to geomagnetic activity and solar irradiance variability

Maliniemi, Ville Aleksi; Asikainen, Timo; Salminen, Antti; Mursula, Kalevi (Peer reviewed; Journal article, 2019)

Recent studies suggest a response in the North Atlantic winter circulation which lags by a couple of years with respect to sunspot maximum. This has been explained by two different top‐down mechanisms: a solar wind driven ...
Comparing the effects of solar-related and terrestrial drivers on the northern polar vortex

Salminen, Antti; Maliniemi, Ville Aleksi; Asikainen, Timo; Mursula, Kalevi (Journal article; Peer reviewed, 2020)

Northern polar vortex experiences significant variability during Arctic winter. Solar activity contributes to this variability via solar irradiance and energetic particle precipitation. Recent studies have found that ...
