Abstract
Predicting weather and climate and its impacts on the environment, including hazards such as floods, droughts and landslides, continues to be one of the main challenges of the 21st century with significant societal and economic implications. At the heart of this challenge, lies the ability to have easy access to hydrometeorological data, to share predictive models, and facilitate the access to High Performance Computing facilities supporting leading edge hydrometeorological simulations.Advances in the science and observation of climate change are providing a clearer understanding of the inherent variability of Earth’s climate system and its likely response to human and natural influences. Extensive uncertainties exist in future forcings of the climate system and in human responses to climate change, suggesting the use of different future scenarios to explore the potential consequences of different response options. Along these lines, numerical simulations of future climate in different emission scenarios, currently being produced in the framework of the fifth climate model intercomparison project (CMIP5), are typically obtained using hydrostatic models and available only at quite coarse spatial resolutions which do not allow an accurate representation of intense precipitation events such as hurricanes, Mediterranean storms or precipitation over complex orography. In this project we will perform high-resolution regional dynamical downscaling of climate scenarios produced by a global climate model, using a state-of-the-art convective model. We will focus on three regions where significant impacts of climate change are expected and where precipitation modeling is particularly challenging due to the formation of intense and complex meteorological structures or to rich and complex orography (The Hindu-Kush-Karakorum, the Mediterranean area, and the Caribbean area).
