Outline of Final Research Achievements |
In this study, we analyzed the cosmogenic nuclides in tree rings and ice cores to investigate the periodic variations of solar activity and the galactic cosmic rays in the past. Based on the time profile, we also examined the long-term variations of large-scale structure of heliospheric magnetic field. In addition, we conducted measurements of oxygen isotopes in tree rings to understand the solar influence on climate. As a result, it turned out that solar activity plays important role in the variations of precipitation in addition to the temperatures. We also examined the possible solar influence on meteorological phenomena focusing on the solar rotational period. As a result, it was suggested that solar activity shows a significant impact even at a meteorological time scale.
