Long term observations of physical and biological variability
in the central and eastern North Pacific show large-amplitude
fluctuations on decadal timescales that are unrelated with the
well-known changes in the sea surface temperatures and the El
Niño Southern Oscillation. By combining these observations with
numerical models that simulate the ocean circulation and the ecosystem
dynamics, I will present evidence of a new emerging pattern of Pacific
climate variability termed the North Pacific Gyre Oscillation. This new
pattern will provide the basis for an improved and unified view of the
Pacific climate dynamics teleconnections and of the mechanisms linking
physical climate variability to the marine ecosystem response.
Dr. Di Lorenzo earned a B.S. from the University of Bologna, Italy and a Ph.D. from the Scripps Institution of Oceanography. He was a postdoctoral researcher with the University of California Los Angeles and the University of California San Diego. He is currently an associate professor in the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology. Dr. Di Lorenzo's research interests include: (1) large-scale dynamics of climate variability and change, (2) regional climate dynamics of the coastal ocean and marine ecosystems, and (3) ocean predictability, inverse ocean dynamics and data assimilation.
