Hydrology Mississippi’s moisture sources in present and future climate In our new study (led by PhD student Imme Benedict), we have assessed the water budget of the Mississippi River Basin under present and future climate conditions. Our main aim was to find out where the precipitation originates from, and in particular whether this comes from land or ocean. To
Weather Mega-heatwave amplification due to upstream drought In a new publication led by Dominik Schumacher of Ghent University (DRY-2-DRY project funded by ERC), we have quantified the impact of upstream drought on mega-heatwaves. With the help of satellite observations and modelling, we quantified the degree to which air masses warm up in drought locations and contribute to
Evaporation Better hydrological cycle with high-resolution global models? To study the global hydrological cycle and its response to a changing climate, we rely on global climate models (GCMs) and global hydrological models (GHMs). In a new paper in HESS, we have evaluated the benefits of increasing the resolution of a GCM and a GHM in simulating the hydrological
Weather Global moisture transport in ERA5 The new ECMWF ERA5 data shows the global moisture transport at an unprecedented detail level. For my atmospheric dynamics class, I have downloaded a year of data at the 850 hPa level (just above the boundary layer) and composed a movie. The movie shows many of the essential ingredients of
