Description of Research

Summary Statement of Research Interests
Professor Stott's research seeks to understand what factors govern the behavior of Earth's climate system. Stott's research group at USC is conducting research at sites located within western tropical Pacific (Indonesia), India and China in an effort to quantify how ocean and atmospheric changes during the past 30,000 years influenced monsoon precipitation. These studies seek improve our understanding of the magnitude and frequency of large-scale drought associated with failure of the monsoon system. Other studies are attempting to define how tropical sea surface temperatures in the Pacific warm pool have changed over time. These studies have uncovered a recurrent pattern of SST variability and surface ocean salinity change in the western tropical Pacific that coincided with global climate changes in the past. These studies suggest that there was a close coupling between tropical and extra-tropical climate on all time scales. The tropical ocean variability is similar to the modern interannual variability we refer to as El Nino/La Nina). Some of the ongoing questions being addressed by Stott's group include: 1.) was ENSO (El Nino/La Nina) active during the last glacial period; 2) did changes in tropical ocean/atmospheric behavior influence the history abrupt climate change during the past 80 thousand years and; 3.) how did tropical Pacific SST respond to changes in ice cover and atmospheric CO2 change at the end of the last glaciation. Answers to the above questions have implications for predicting how climate may vary in the future.
