15A.6
The Global Warming Events in the Past 60 years
Michael Davis, The Ohio State University, Columbus, OH; and J. Lin and S. Stuckman
The impacts of global climate change have been analyzed for the past few decades. Up until this point, an average of the time series was taken in order to perform this prediction. However, if each year is treated as an individual warming event then the results may be spatially or temporally different. Temperature and precipitation patterns may be altered providing a new insight into potential outcomes of global climate change. These changes may be influenced on the natural, anthropogenic or a combination of both causes. Analysis on temperature patterns provides warmer than normal SST in the Indian Ocean and central Atlantic Ocean with a colder than normal SST anomaly in the north central Pacific Ocean. Differences in land temperature and ocean temperature are found to occur in these climate simulations mostly in the Northern Hemisphere where this contrast is most profound. Sea level pressure anomalies are greater in the Oceania region and weaker in the southeastern Pacific which could indicate the enhancement of the Walker Circulation. Furthermore, a deepening of the Aleutian Low is shown to become a dominate feature in the Northern Hemisphere. Significant precipitation anomalies remain primarily confined to the tropical regions leaving them at most risk for extreme precipitation events.
