• Outline

     I am currently working on convection representation in climate models. If convection is not accurately represented, what kind of errors does it pose in the climate simulations? Do current climate models have skill in representing convection, then how to quantify them? How important is the diurnal cycle? Another challenging area is, how convection responds under different forcings and scenarios in the climate models. How can data assimilation improve convection representation? How can we use data assimilation and artificial intelligence to understand convection?
