About my research

I'm a post-doc at the Max-Planck-Institute for Meteorology.  My research topic is the understanding of the temporal changes in the area and intensity of the tropical rainbelt. In particular, my interest is to understand the mechanisms (large-scale or mesoscale) driving the regional differences in the tropical rainbelt on seasonal and interannual time scales. This interest has involved me in the analysis of tropical precipitation and its representation in global-coupled storm-resolving models (GSRM). Topics such as the reproduction of the ITCZ and monsoon systems are fundamental questions of my study. Moreover, GSRMs have allowed me to explore the feedback between air-sea interaction and tropical precipitation.
