Nedjeljka Žagar


Welcome to my homepage!

I am a postdoctoral fellow within the Advanced Study Program (ASP) at the National Center for Atmospheric Research .
I received my BSc and MSc in physics/atmospheric physics from the Faculty of Sciences at the University of Zagreb and my PhD from the Department of Meteorology at the Stockholm University . The title of my doctoral dissertation was "Dynamical aspects of atmospheric data assimilation in the tropics" (pdf).

My research interests range from modelling the mid-latitude mesoscale weather to large-scale variability.
My main research topic at present is data assimilation. I am interested in (im)balances which (do not) exist at large scales in the tropics and their manifestation in data assimilation. The goal is to improve understanding of the mass-wind couplings in the tropics and understanding of the flow-dependency of background-error covariances and thereby to improve the data assimilation procedures and to reduce uncertainties in the tropical analysis fields.
