HyDROS scientists Dr. Pierre Kirstetter and Dr. Jonathan Gourley (NOAA/NSSL) have been invited toparticipate in the Hydrological Cycle in the Mediterranean Experiment (HyMeX), the largest weather field research project in European history. HyMeX is a 10-year international effort to better understand, quantify and model the hydrologic cycle in support of improved forecasts and warnings of flash floods in the Mediterranean region. Improved understanding of the land,atmosphere and ocean interactions that contribute to flash flooding in this part of the world will advance the state of the science that will ultimately be represented in forecast models with application in the United States.
