Matt Reszka

Post-doctoral Fellow - research in dynamical and statistical constraints for variational data assimilation, generation of global atmospheric analyses for International Polar Year project

Current research and/or projects

Improvement in weather/climate forecasts through modification of existing assimilation constraints, and contribution to international research effort focussed on polar regions

  • Atmospheric dynamics, particularly balance relationships between meteorological fields and the use of such relationships as constraints in forecasting
  • Theoretical development of balance constraints applicable to the tropical regions and implementation in existing assimilation systems
  • Statistical methods for specification of background error variances and covariances
  • Implementation and management of a global 4D-Var assimilation system using a forecast model with online chemistry
  • Investigation of stratospheric processes, including sudden stratospheric warmings, the ozone cycle and tropical waves, as well as their role in the climate system
