The Ocean Circulation Group focuses on studies of the physical processes of the ocean and its interaction with other elements of Earth's climate system. Ongoing research topics include,

• Sea level variability
• Seasonal-to-interannual climate variability; El Nino/Southern Oscillation (ENSO), Monsoon, Indian Ocean Dipole (IOD), North Atlantic Oscillation (NAO)
• Decadal climate change; Pacific Decadal Oscillation (PDO) and Indian Ocean warming
• Global warming
• Air-sea interaction
• Water and heat transport
• Ocean mass variability
• Oceanic waves; planetary waves, inertial-gravity waves, tsunamis
• Model development and model applications
• Data assimilation

Our research is founded on application of satellite remote sensing of the ocean and atmosphere, and employs a comprehensive approach that consists of data analyses, analytical and numerical modeling, and data assimilation. The studies also include investigations in developing new observing systems, advancements in modeling and data assimilation methodologies, and expansion of capabilities and scope of data analysis techniques.
