| Research Abstract |
We investigated the missing link of solar magnetic activity-climate connection on the basis of our recent finding that solar wind parameters correlate well with temperatures and the Arctic Oscillation and correlation. As a cause to produce the correlation of stratosphere temperature and solar wind parameter, the study of solar wind particles accretion appeared realistic because of easy access to stratospheric ozone data. We investigated correlation between the solar wind and global grid data of the total ozone, and Thus, we have proposed a mechanism in which NO generated by solar wind particles in the ionosphere is transported to the stratosphere, to reduce the ozone, and to modulate the temperature of the stratosphere.
