Seminar Room MCZ, 440

Speaker: Packard Chan

Packard Chan will be presenting on Horton et. al. (2015). His thoughts on the paper are:

The possible link between changes in atmospheric circulation and extreme temperature is recently a hot topic of research. However, the long-term change in atmospheric circulation remains inconclusive. Employing self-organizing map (SOM) cluster analysis for seven regions of the Northern Hemisphere, this paper identified statistically significant trends in the occurrence of some circulation patterns. By doing a quantitative partitioning, the paper found that while a substantial portion of the observed change in extreme temperature occurrence has resulted from regional- and global-scale thermodynamic changes, the change in occurrence and persistence of regional circulation pattern is also altering the risk of extreme temperatures.
