Abstract The new Coordinated Output for Regional Evaluations (CORDEX-CORE) ensemble provides high-resolution, consistent regional climate change projections the major inhabited areas of world. It serves as a solid scientific basis further research related to vulnerability, impact, adaptation and services in addition existing CORDEX simulations. aim this study is investigate document information provided by CORDEX-CORE simulation ensemble, part World Climate Research Programme (WCRP)...
Abstract A large ensemble of hydroclimatic simulations is used to simulate the occurrence river floods over Europe in a climate change context. routing model derived from distributed hydrological (CHyM) forced with 44 EURO‐CORDEX, 13 CMIP5 and 7 CMIP6 assess effects on flood magnitude under two different scenarios. The impact evaluated using 100‐year return period discharge indicator (Q100). Results show decrease Q100 events Mediterranean, Scandinavia north eastern Europe. This latter signal...
Abstract We describe the first effort within Coordinated Regional Climate Downscaling Experiment–Coordinated Output for Evaluation, or CORDEX-CORE EXP-I. It consists of a set twenty-first-century projections with two regional climate models (RCMs) downscaling three global model (GCM) simulations from CMIP5 program, greenhouse gas concentration pathways (RCP8.5 and RCP2.6), over nine CORDEX domains at ∼25-km grid spacing. Illustrative examples initial analysis this ensemble are presented,...
Abstract. We describe the development of a non-hydrostatic version regional climate model RegCM4, called RegCM4-NH, for use at convection-permitting resolutions. The dynamical core Mesoscale Model MM5 is introduced in with some modifications to increase stability and applicability long-term simulations. Newly available explicit microphysics schemes are also described, three case studies intense convection events carried out order illustrate performance model. They all run grid spacing 3 km...
Abstract We describe a new, state‐of‐the‐art, Earth System Regional Climate Model (RegCM‐ES), which includes the coupling between atmosphere, ocean, and land surface, as well hydrological ocean biogeochemistry model, with capability of using variety physical parameterizations. The regional coupled model has been implemented tested over some COordinated climate Downscaling Experiment (CORDEX) domains more settings featuring climatically important phenomena. ocean‐atmosphere models can be...
Abstract We introduce a new version of the Earth System Regional Climate model RegCM‐ES and evaluate its performances for first time over Mediterranean region. The novel aspect this coupled system is possibility to simulate dynamics marine ecosystem through biogeochemical model, BFM (Biogeochemical Flux Model), online with ocean circulation MITgcm (MIT general model). validation atmosphere components has shown that able capture interannual intermonthly variabilities atmospheric heat fluxes...
Abstract The identification of flood prone areas is essential for a range engineering, risk reduction and research applications. Here, we describe combined hydrological hydraulic modelling approach the assessment flood‐prone present results obtained over Po river (Northern Italy). Runoff discharges are calculated through model CHyM driven by GRIPHO, new precipitation dataset Italy. River flow data used to obtain hydrographs CA2D model, which calculates hazard maps at resolution 90 m. Flood...
Abstract. Identification of flood prone areas is instrumental for a large number applications, ranging from engineering to climate change studies, and provides essential information planning effective emergency responses. In this work we describe an integrated hydrological hydraulic modeling approach the assessment flood-prone in Italy present first results obtained over Po river (Northern Italy) at resolution 90 m. River discharges are through model CHyM driven by GRIPHO, newly-developed...
Abstract The internal and ENSO-forced modes of the Indian Ocean sea surface temperature (SST) are investigated using a high-resolution regional coupled model. Five different model simulations were performed by controlling atmospheric oceanic boundary conditions (BCs), which lateral walls domain. In run prescribing climatological mean BCs, first second empirical orthogonal functions (EOF1 EOF2) mode similar to observed basin (IOB) dipole (IOD) with relatively weak amplitudes, respectively....

<p>Hindukush Karakorum and Himalayan (HKH) is a unique region with vast number of glaciers lies in the north South Asia landmass, which serves as main reservoir for Asian freshwater resources. By using CORDEX-CORE downscaled simulations ICTP Regional Climate Model (RegCM4.7) climate change impact on water resources HKH analysed. contains Indus, Ganges Brahmaputra basins, are feed from both snow well precipitation.

<p>One of the most largely recognized effect Global Warming is change weather extremes. The increase extreme precipitation events directly linked to a greater availability precipitable water induced by warmer atmosphere.The flood projected signals are heterogeneous and influenced different phenomena. As an example, rise in temperature could risk floods over regions sensible precipitations at same time reduce melted snow accumulated during cold season. In this work CORDEX-CORE...
Rivers have been a vital part of the natural system, favoring development different countries and their economies. However, river system may undergo significant changes as result climate change, with implications for water management, agriculture, aquatic ecosystems. This study investigates future hydrological drought risks worldwide through an ensemble regional hydroclimatic projections CORDEX domains (i.e., CORDEX-CORE simulations). For this, routing model derived from CETEMPS Hydrological...
<p>In a sick world with fever caused by global warming, the hydrological cycle will experience most certainly large changes in intensity and variability. One of intense phenomena that probably be affected climate change is flood hazard. For long time stakeholders have been dedicated resources to assess risk linked floods magnitude frequencies shaping public infrastructures based on assumption their immutability. Under effect this can broken different approach should followed...
