Scott Power - Academia.edu (original) (raw)

Dr. Scott Power Dip. Ed. is the head of climate research and the International Development Manager in the Bureau of Meteorology. He is a Coordinating Lead Author of the latest IPCC WGI report and an author of the latest IPCC WGI-III Synthesis Report (http://www.ipcc.ch/). Scott has published extensively in the international scientific literature on global warming, El Niño, decade-to-decade climate variability and historical changes in severe weather. He is the former head of operational climate monitoring and prediction in the Bureau and a former acting head of Australia’s National Climate Centre. He previously coordinated the Bureau's participation in the Australian Climate Change Science Program, he led the development of a project to enhance climate prediction services in numerous Pacific Island countries, and was co-chair of the Pacific Climate Change Science Program (http://www.pacificclimatechangescience.org) that assisted 15 vulnerable countries adapt to climate change.

Research paper thumbnail of El Niño-Southern Oscillation complexity

Such conditions are accompanied by changes in atmospheric and oceanic circulation, affecting global climate, marine and terrestrial ecosystems, fisheries and human activities. The alternation of warm El Niño and cold La Niña conditions, referred to as the El Niño-Southern Oscillation (ENSO), represents the strongest year-to-year fluctuation of the global climate system. Here we provide a synopsis of our current understanding of the spatio-temporal complexity of this important climate mode and its influence on the Earth system.

Composites of SST and mean sea level pressure anomalies reveal that the IPO has maintained a broadly stable structure across the seven most recent positive and negative epochs that occurred during 1870-2013. The TPI is shown to be a robust and stable representation of the IPO phenomenon in instrumental records, with relatively more variance in decadal than shorter timescales compared to Niño 3.4, due to the explicit inclusion of off-equatorial SST variability associated with the IPO.

Research paper thumbnail of A non-flux corrected transient CO 2 experiment using the BMRC Coupled Atmosphere/Ocean GCM

Geophysical Research Letters, 1995

No flux corrections were used in the experiment. A roughly linear temporal increase in global surface temperature is found in response to the CO2 increase. The rate of increase is consistent with the (relatively low) equilibrium response found previously using the Atmospheric GCM and a simple ocean. Ocean surface temperatures increase more at mid latitudes than at high northern or southern latitudes where heat is sequestered into the deep ocean. Despite the secular climate drift which occurs in the model, the major patterns of atmospheric and oceanic temperature change are similar to changes noted elsewhere (from flux corrected models). This adds further support to the main conclusions drawn from transient CO2 experiments performed elsewhere with coupled GCMs.
