abstract = {The number of extreme hydroclimatic events (e.g., droughts,
heat waves, heavy precipitation) increased during the recent
years, and will likely occur even more often in the future
(e.g., Hari et al. 2020; Molina et al. 2020; IPCC, 2021),
resulting in multiple socio-economic impacts. In order to
develop useful adaptation strategies consistent,
high-resolution climate data are needed. The groundwater
(GW) representation in most regional climate models (RCMs)
is generally oversimplified or absent, as well as its
interaction with soil moisture and atmosphere, leading to
biases in simulation of extreme heat events. In fact, many
RCMs overestimate the heat waves frequency, duration and
intensity (e.g., Vautard et al. 2013; Lhotka et al. 2018).In
this project, we explicitly simulate full 3D soil and GW
dynamics, closing the terrestrial water cycle from GW across
the land surface into the atmosphere, by utilizing the
Terrestrial Systems Modelling Platform (TSMP) over the
EURO-CORDEX domain. We obtained all terrestrial essential
climate variables and indices for historical time span and
the climate change projections with the Representative
Concentration Pathways (RCP) 2.6 and RCP 8.5 (a rise in
global temperature by 1.5°C and 4°C by 2100 respectively).
Our analysis focused on the assessment of the effects of GW
on the evolution of heat waves by investigating its
frequency, duration and intensity.},
