Modal View of Atmospheric Variability

lt;p>Nedjeljka Zagar is a professor of meteorology at University of Ljubljana (University of Hamburg). Her research covers topics in atmospheric dynamics and numerical weather prediction, especially tropical aspects. She has been using the normal-mode functions for data assimilation modelling and for quantification of atmospheric variability across many spatio-temporal scales with focus on unbalanced circulation.

Joseph Tribbia is a senior scientist at the National Center for Atmospheric Research (NCAR) and Head of its Atmospheric Modeling and Predictability Section in the Climate and Global Dynamics Division. He received a Bachelor of Science in Physics from the Illinois Institute of Technology in 1971, and a masters and doctoral degree in Atmospheric Science from the University of Michigan. He has been at NCAR since 1978 and his work has focused on the numerical simulation of the atmosphere and geophysically relevant flows. His journal publications include works on the application of dynamical systems theory in atmospheric dynamics, the problems of atmospheric data analysis and numerical weather prediction, atmospheric predictability and the prediction of forecast reliability, the simulation and prediction of El Nino/Southern Oscillation and decadal climate projections.
