DRIP - DRought ending in Intensified Precipitation

This project aims to estimate the change in frequency and intensity of DRIP events with global warming due to changes in the water-cycle. We will identify actual historical compound DRIP events and find indices that are suitable to identify these events in model data. As global climate models show a large spread in precipitation for both historical and the different future climate projections, there is expected to be a spread in model projections of DRIP events as well. We will constrain this spread by identifying global climate models that do a good statistical representation of historical DRIP events and by analyzing large ensembles to evaluate the natural variability. As higher resolution modelling shows a better representation of the water cycle, the project will analyze regional downscaled global models in identified regions of interest. We will also perform in-house regional simulations of identified global models down to convection permitting scale to study the change in DRIP events with model resolution. The project will also target a highlighted uncertainty connected to the water-cycle by exploring how evapotranspiration and the occurrence of DRIP events found in climate models respond to land use change. For this analysis we will extend the regional downscaling to include sensitivity studies which contain deforestation and forestation. Results gained from DRIP will make a large contribution to the knowledge needed on future mitigation measures due to the increase in compound events.
