Welcome to the website for the Convective Storm Dynamics Group, led by Prof. James Ruppert!

Through our research we seek to better understand the dynamics of convective cloud systems and their two-way feedback with larger scales. This feedback is sometimes called the weather–climate interface. Cloud–radiation feedback is a prime example: while the structure and distribution of clouds are greatly shaped by the climate in which they form, the clouds play a key role in determining albedo and local greenhouse radiative trapping, therefore greatly shaping climate through radiative balance. To study these links we invoke knowledge and tools across a range of scales, while the lessons of our research have implications over a number of areas of atmospheric science, including severe and hazardous weather, climate variability and change, and the prediction of weather and climate.

Our primary research tools include numerical modeling, theoretical analysis, reanalysis datasets, and observations. Experiments using high-resolution numerical models (WRF, MPAS, ICON, CM1) are an especially vital tool in our research, as are the supercomputers we run them on.

Our primary research topics include:

  • Tropical mesoscale to large-scale dynamics
  • Tropical cyclones
  • Cloud–radiation feedback
  • The Madden–Julian Oscillation
  • Air–sea interaction
  • The diurnal cycle
  • Monsoons
  • Self-aggregation
