The theoretical tools we use include idealized models of the atmosphere and oceans which are amenable to mathematical analysis, an idealized general circulation model (FMS), as well as the analysis of comprehensive climate models (e.g., CMIP and PMIP models). We also aim to anchor the research in observations. To handle the large variety of observational and modeling datasets, we use a software tool called GOAT (Geophysical Observation Analysis Tool).
Current research projects include:
- Idealised coupled cloud-ocean-atmosphere models
- The effect of continent distribution on tropical climate
- The relation of the atmospheric energy budget and tropical precipitation
- Origin and nature of the double ITCZ bias
- Variations of the tropical rain belt in the present and past climates
- Relating the Hadley cell strength to the atmospheric energy budget
