The research topics of the group revolve around climate dynamics, with emphasis on tropical atmosphere dynamics.

We strive to understand the underlying principles behind the dynamics of large-scale natural phenomena in the atmosphere and oceans. The tools we use combine observational analysis with theoretical analysis using a hierarchy of models across a range of complexities.

Currently, active research projects include:

  • Conceptual models of tropical circulations
  • The width of the tropics (Tropical Width Diagnostics Working Group)
  • The effect of continent distribution on tropical climate
  • The relation of the atmospheric energy budget and tropical precipitation
  • Monsoon dynamics

The theoretical tools we use include idealized models of the atmosphere and oceans which are amenable to mathematical analysis, an intermediate-complexity general circulation model (FMS), as well as the analysis of comprehensive climate 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).
