Researcher Drought Propagation / Atmospheric Moisture Transport

The Mediterranean region is deemed as a future hotspot of drought occurrence. However, to accurately predict and anticipate droughts in the region, the mechanisms behind their spatiotemporal evolution still need to be better understood. Recent evidence indicates that within-continent atmospheric transport is critical for the expansion and concatenation of droughts in semiarid regions (Schumacher et al. 2022). However, whether these processes modulate drought propagation in the Mediterranean region remains unknown. New high-resolution satellite data from the 4DMED-Hydrology project can help steer a moisture tracking framework (Keune et al. 2022) and unveil the influence of land feedbacks on drought occurrence in the Mediterranean.
