Aerosol and Solar Irradiance Effects on Decadal Climate Variability and Predictability
The expanding interest in decadal climate variability, predictability, and prediction highlights the importance of understanding the sources and mechanisms of decadal and interdecadal climate fluctuations. The purpose of this paper is to provide a critical review of our current understanding of exte...
