      abstract     = {Long-term groundwater droughts are known to persist over
                      timescales from multiple years up to decades. The mechanisms
                      leading to drought persistence are, however, only partly
                      understood. Applying a unique terrestrial system modeling
                      platform in a probabilistic simulation framework over
                      Europe, we discovered an important positive feedback
                      mechanism from groundwater into the atmosphere that may
                      increase drought persistence at interannual time scales over
                      large continental regions. In the feedback loop, groundwater
                      drought systematically increases net solar radiation via a
                      cloud feedback, which, in turn, increases the drying of the
                      land. In commonly applied climate and Earth system models,
                      this feedback cannot be simulated due to a lack of
                      groundwater memory effects in the representation of
                      terrestrial hydrology. Thus, drought persistence and
                      compound events may be underestimated in current climate
                      projections.},
