Matt Reszka
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
