    Anurag DIPANKAR (ETH Zürich, EXCLAIM project)

    The modern exascale computing systems have given the climate and weather modeling community an opportunity for a step change in their simulation capabilities. One expects a grid resolution sufficiently large to resolve the key atmospheric processes provided the machine is properly utilized. However, this is a non-trivial task. Given the complexities at various levels from the hardware to the software (model), the conventional software needs to be redesigned in a way that it fully utilizes the exascale capabilities while keeping it easy to use.

    Alexander CHERNOKULSKY (A.M. Obukhov Institute of Atmospheric Physics, Russian Academy of Sciences)

    Climate change leads to an increase in surface air temperature and an intensification of the hydrological cycle by accelerating the rates of atmospheric water vapor content, precipitation, and evaporation. One of the most prominent visualizations of such intensification is the increase in the severity of extreme convective events, including very heavy showers, large hail, linear storms, and tornadoes. The talk will provide an overview of studies of severe convective events over Europe and northern Eurasia and the relationship of their intensity and frequency to ongoing climate change.

    Enabling evaluations of how models simulate with water cycle using stable water isotopes.

    The hydrological cycle, with its feedbacks related to water vapor and clouds, is a large source of uncertainty in weather prediction and climate models. These uncertainties are linked to several of the current major challenges in meteorology and climate research, including the formation of extreme weather events, quantifying the impacts of man-made climate change, and deciphering the climate record from paleoarchives. This talk explores how combining precise measurements of stable isotopes in water vapor, rain and snow with advanced modelling tools allows to extract more details of the entire transport history from the isotope composition of atmospheric waters. The ability to observe where the water in precipitation comes from, and how and where it is affected by phase changes during its journey through the water cycle in the atmosphere, opens doors towards stronger theoretical and numerical constraints when modelling the coupled Earth System.
