My present research interests are in climate dynamics and dynamic meteorology. Most of the studies I have been involved in are associated with numerical simulations of the atmosphere. Most of these simulations are so-called sensitivity experiments where we use models to study the impact of certain processes or (sea)surface properties on the climate 

Research topics I have been involved in:

 

  • Parameterisation of cloud processes in numerical models
  • Mesoscale atmospheric dynamics
  • Climate modeling and climate analysis
  • Large-scale atmosphere ocean interaction 
  • Large-scale variability and storm-tracks
