Assessing the roles of oceanic processes, particularly ocean stratification and mixing, in ocean-atmosphere interactions that dictate the genesis and evolution of extreme weather.
Examining long-term anomalous changes of physical processes, specifically western boundary currents and meridional overturning circulations, that control inter-ocean exchanges of heat and freshwater and their implications on weather and climate variability.
Extracting dynamical constraints from multi-faceted observations in terms of large-scale oceanic waves theory.

“The ocean responds slowly to energetic, rapidly moving, and evolving atmospheric disturbances, with the oceanic response continuing after the disturbances have passed. The relatively slow response time of the ocean is reflective of its high heat capacity and density and may introduce a memory effect into subsequent atmospheric disturbances.”
Dr. Kandaga Pujiana is an Assistant Scientist at the Cooperative Institute for Marine and Atmospheric Studies at the University of Miami. He completed his Ph.D. in Ocean and Climate Physics at Columbia University. Dr. Pujiana’s research interests extend from examining the importance of oceanic processes in ocean-atmosphere interactions to extracting dynamical constraints from multi-faceted observations in terms of theory for large-scale ocean circulations and waves. His current research attempts to assess anomalous changes in oceanic processes such as western boundary currents and the meridional overturning circulation, with significant implications on inter-ocean heat and freshwater exchanges and potentially climate variability. Dr. Pujiana is apart of the XBT science team at AOML.
