GS Marena Lin be presenting Zhang et al. (1997) and says the following about the paper:Recent work has suggested that the apparent decline in global mean temperature rise is related to the current negative phase of the Pacific Decadal Oscillation (PDO). Motivated by the apparent shift in temporal variability of Pacific Ocean surface temperatures between the 1950-1976 and 1977-93 epochs, Zhang et al. (1997) was the first to delineate this interdecadal mode of variability and its relationship with global surface temperatures. They contrast it with better-known global teleconnections related to ENSO variability. I plan to discuss the computation and implications of the resulting PDO index and ways in which it may be related to global surface temperature variability and recent global mean temperature trends.
