Ocean atmosphere dynamic interaction processes related to short-term and long-term climate variability. 2-layer models and physics of El Nino/southern oscillation, North Atlantic Oscillation and monsoon dynamics are discussed with the perspective of global climate change. During the semester the class will conduct a real-time monitoring experiment of the Pacific/Atlantic Ocean using the Internet. Also presented are advanced assimilation techniques of satellite (GEOSTAT, Topex/Poseidon, SeaWifs, MODAS) and in-situ data from the World Ocean Circulation Experiment (WOCE) in numerical climate models.
