Particle Events as a Possible Source of Large Ozone Loss During Magnetic Polarity Transitions.

摘要

This paper concerns the possibility that very large solar proton events, which occurred during periods of the Earth's magnetic reversal, might have caused fairly substantial ozone losses in the past. Large-scale explosions on the Sun near solar maximum lead to emissions of charged particles (mainly protons and electrons) from the Sun. Occasionally the Earth is positioned in its orbit such that these solar particles interact with the Earth's magnetosphere and rain down only on the polar regions. 'Solar proton events' have been used to describe these phenomena since the protons associated with these solar events cause the most atmospheric disturbance.
