Multi-Year Droughts: Robust Understanding and Information Generated by Enhanced Process Determination

Project description

Improving our understanding of multi-year droughts in Europe

Droughts impact personal experiences and worsen with longer durations. Recent multi-year droughts (MYD) in Europe highlight adaptation challenges. While the general causes of drought are known, the specific drivers of MYD, such as missed rainfall or soil memory, remain unclear. Furthermore, it is not known how climate change will affect these factors. Supported by the Marie Skłodowska-Curie Actions programme, the MYDROUGHT project aims to enhance understanding of MYD in Europe by combining various data sources, including paleo data and advanced statistics, to identify natural drivers and the impacts of short-term droughts. It will use a robust MYD sample for model simulations to explore how pre-existing drought conditions affect MYD occurrence.

Objective

Droughts easily enter the realm of personal experience. Their socio-economic and ecologic impacts aggravate with longer event duration and cascade into multiple sectors. Recent events, as 2018-2020 in Europe, remind us of droughts in consecutive years with high stress to adaptation: multi-year droughts (MYD). While the general understanding of drought drivers is high, causes for MYD development are poorly understood. Do MYD miss drought-ending rainfall events or is the memory effect of soils the main culprit? How will climate change affect the interplay of MYD drivers? In MYDROUGHT, I will answer these questions with University of Graz. I will provide the best-informed understanding on the natural drivers of MYD, with a special focus on Europe. Since MYD are rare events, I will innovatively combine different lines of evidence to obtain reliable information: In a novel evaluation approach, paleo data (a) will contextualize the representation of MYD in climate models. In large ensemble data and during a secondment in Wageningen (b), I will identify drivers of ‘typical’ MYD using cutting-edge statistics and embracing the very recent paradigm of investigating drought ends. With the large sample of MYD, the results will be statistically robust. A small selection of these MYD will serve as starting point for (c) where I will employ a novel model experiment set-up: a storyline simulation in a hemispheric domain with weather conditions of ‘short droughts’ inserted before a MYD – will they still produce a MYD? To integrate my findings, I will develop a framework that considers attributes of robustness which will be discussed in a new international task team of which I am a member. In the mid-term, MYDROUGHT aims at fostering resilience towards MYDs to limit socio-economic and ecological losses. With MYDROUGHT and the expertise gathered, I will be perfectly equipped to apply for junior group leader positions for continuing this research.
