The extreme 2018 and 2022 droughts pose as recent examples of a series of drought events that have hit Europe over the last decades with wide ranging social, environmental and economic impacts. Although the link between atmospheric circulation and meteorological drought is clear and often highlighted during major drought events, there is a lack of in-depth studies linking historical changes in meteorological drought indices and prevailing large-scale atmospheric patterns in Europe. To meet this shortfall, we investigated the relation between changes in large-scale atmospheric patterns and meteorological drought, as indicated by the geopotential height at 500mb (Z500) and the Standardised Precipitation-Evapotranspiration Index (SPEI), respectively.

For example, they help to predict how terrestrial plants interact with climate, soils, disturbance and competition for resources. We argue that there is untapped potential for the use of DGVMs in ecological and ecophysiological research.

- - Recent European droughts raise concerns about whether observable changes in drought frequency align with climate change predictions, leading to questions about different drought types and their impacts.
- - This study is the first to identify regional differences in drought likelihood in Europe from 1958-2014, using major drought indices (SPI and SPEI) to show increasing droughts in southern Europe and decreases in northern Europe.
- - The findings suggest that rising temperatures have contributed to more frequent droughts in southern Europe while lessening the effectiveness of increased precipitation in northern Europe, aligning with climate change projections and revealing inconsistencies among drought indices.
