| Zusammenfassung |
| It is well known that atmospheric variables can be influenced to change by aerosol
concentration. In spite of a wealth of studies, however, it is still remain unclear how the
regional anthropogenic aerosol in East Asia affects the climate variability in the North
Pacific. In this study, we examined the effect of anthropogenic aerosol forcing in East Asia
(GEOS-Chem) on the climate variability in the North Pacific based on a global
chemical transport model and three idealized experiments using an atmosphere
model. GEOS-Chem is forced by the assimilated meteorology from the Modern-Era
Retrospective Analysis for Research and Applications of the National Aeronautics and
Space Administration for 1985-2010. Regarding three experiments, the first set
used the historical SST for 1985-2010 with the time-varying emissions in East
Asia. The second set used the historical SST without the emissions and the third set
included the climatological SST with the time-varying emissions in East Asia. By
comparing GEOS-Chem run with atmosphere model runs, we analyze the role of
regional aerosol forcing in East Asia on the climate variability in the North Pacific. |
