This bilateral/joint German (DFG) - Czech (GACR) project XEROS (meaning 'dry' in Greek) represents a unique opportunity of bringing together two research groups of complementary scientific knowledge. The German-based team (CHS @UFZ) focus on understanding and modelling the complex interaction of land-surface hydrologic processes and their spatial and temporal variability at meso- to macro-scales. The Czech-based team (@ CULS) have strong scientific background in statistical analysis of hydrologic and climate variability.
[March 2021] Our new paper on "Europe under multi-year droughts: how severe was the 2014–2018 drought period?" was published in Environmental Research Letters. We demonstrate that when the multi-year 2014–2018 period is considered, its soil moisture drought severity is exceptional in a 253 year period, especially for Central Europe
[February 2021] Our new paper on "The rise of compound warm-season droughts in Europe" was published in Science Advances. We analysed drought typology to assess the fluctuations of European drought seasonality and duration since 1900. UFZ press-release
[December 2020] Our paper on "On the curious case of the recent decade, mid-spring precipitation deficit in central Europe" was published in npj Climate and Atmospheric Science. UFZ press-release AWI press-release
[August 2020] Our paper on "Increased future occurrences of the exceptional 2018–2019 Central European drought under global warming" was published in Scientific reports. Nature Research highlights. UFZ press-release.
The overarching goal of this project is to address the following research questions:
- What is the extremity of the recent European drought events compared to the 500-year benchmark period?
- How does the space-time variability of drought evolution change over time?
- How do the large-scale atmospheric characteristics, responsible to generate land-surface droughts, co-evolve? How can we enhance the reliability of future hydro-climatic projections?
- WP-1a: Historical reconstruction of climate forcing data to allow hydrologic simulations at finer spatial and temporal resolution. [led by the CULS team]
- WP-1b: Multi-model hydrologic simulations of key hydrologic variables [led by the UFZ team]
- WP-2a: Historical characterisation of large scale drought events [led jointly by the UFZ and CULS teams].
- WP-2b: Improved understanding on genesis of the large scale drought events [led by the CULS team]
- WP-3: Enhancing the reliability of future hydro-climatic projections [led by the UFZ team]
