Professional Profile

Zoltan Toth, Senior Scientist


Dr. Zoltan Toth is a Senior Scientist at the Global Systems Laboratory (GSL) with NOAA Research. His research has covered topics in atmospheric and related dynamical systems, including the dimensionality and equilibrium properties of the climatic phase space, the limits of predictability, ensemble forecasting, theoretical and practical aspects of data assimilation, uncertainties in numerical modeling, sensitivity studies, and the statistical calibration and socio-economic use of weather forecasts.
 
Prior to joining NOAA Research, at the Environmental Modeling Center (EMC) of the National Centers for Environmental Prediction (NCEP), Dr. Toth led the development and first-ever operational implementation of the Global Ensemble Forecast System (GEFS, 1992), the Winter Storm Reconnaissance program (WSR, 2001), and the North American Ensemble Forecast System (NAEFS, 2006).
 
Dr. Toth played leadership roles in various national and international research organizations and programs, has been an editor of international journals, gave over 70 invited presentations, collaborated with over 400 scientists across the globe, and authored more than 80 refereed publications.

Research Interests 

Weather and climate predictability; Study of the nature and quantitative behavior of error variance in numerical analysis and forecast fields; The fundamental properties of data assimilation, forecast, and ensemble prediction systems; The effect of observing systems on the quality of numerical analyses and forecasts; Statistical post-processing of numerical weather forecasts.
