Modal View of Atmospheric Variability: Applications of Normal-Mode Function Decomposition in Weather and Climate Research

Nedjeljka Zagar is a professor of theoretical meteorology at Universität Hamburg. She received a BSc and a MSc in physics from the University of Zagreb, a PhD in dynamical meteorology from Stockholm University, and a postdoctoral fellowship from the Advanced Study Program of NCAR. She has been a professor of meteorology at the University of Ljubljana. Her research covers topics in atmospheric dynamics and numerical weather prediction, focusing on tropical aspects of data assimilation and predictability.

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.
