The present study describes a simulation of the past period 1979-2011 performed with the regional climate model COSMO-CLM over the Chinese region. To carry out this simulation, the ERA-Interim Reanalyses have been used as forcing and a resolution of 0.125◦ (about 14km) has been adopted. The results have been validated by using the CRU observational dataset.This activity has been conducted in the framework of WP 7.1.6 of the "B action" in the Gemina project, whose main aim is to develop high resolution climate projections over China for XXI century.

This study presents the results of a dynamically downscaled high resolution (about 8 km) climate simulation over Italy, produced with COSMO-CLM model, forced by ERA-Interim reanalysis and covering the time period from 1979 to 2011. Model results have been analysed in terms of two-meter temperature and precipitations. The main aim of this work is to assess the capabilities of high-resolution simulations in reproducing the main features of the Italian climate, in order to provide a reliable tool for impact studies on local scale. Validation of results has been performed comparing model output with different observational data.

This report represents the description of the first activity performed within the work package 7.1.6 of the "B action" in the Gemina project. The "B action" of the Gemina project concerns the consolidation and development of international scientific network. In particular the cooperation between China and Italy is focused on the development of regional climate scenarios and the analysis of impacts on coastal areas on the Chinese region. The main goal of the WP 7.1.6. is to provide high climate simulation on the China region for the XXI century. In order to perform this activity, some preliminary simulations are requested, to find an optimal configuration for the high resolution climate model COSMO CLM. This report contains the description of the sensitivity analysis developed on a limited part of the Chinese region.

In this paper, the capabilities of COSMO CLM on simulating the main features of the observed climate over the whole Mediterranean area have been analyzed. The investigated period is 1971-2000. A simulation driven by ERA40 Reanalysis has been performed at a spatial resolution of 14 km in order to provide an assessment of regional model performance on local scale for impact studies. 2-metres mean temperature and total precipitation simulated values have been compared with E-OBS observational dataset; moreover, the total cloud cover has been validated with respect to the ERA-Interim Reanalysis.

This document describes the numerical models and tools constituting the integrated system for the qualitative and quantitative assessment of the hydrogeological risks due to climate change developed in the framework of the GEMINA project (product P91). In particular the work package 6.2.17 'Analysis of geological risk related to climate change' has as main goal the analysis of landslides, floods and droughts risks related to climate change conditions on the Mediterranean area. The integrated system combines, in appropriate way, high-resolution regional climate scenarios, impact models and statistical downscaling techniques. All these are described in the current document. In addition, this document contains a description of the test cases on which the integrated system will be verified.

The aim of this report is to analyze the sensitivity of the precipitation and the 2-meters mean temperature on the variation of some physical, numerical and tuning parameters in the regional climate model COSMO-CLM over the north and center Italy. The simulations, at a spatial resolution of 8 km and concerning the period 1996-2000, are driven by ERA40 Reanalysis. Five different sub-areas inside the computational domain have been selected, chacterized by different orographic features; the seasonal cycle has been calculated for each simulation and compared with three different data sets: E-OBS, ETH and ARPA-EMR data set. This report represents the product P15 of the GEMINA project.

This paper analyzes the capabilities of the regional climate model COSMO-CLM to simulate the main features of the observed climate over the entire Italian domain. Two simulations on the period 1971-2000, driven by ERA40 Reanalysis and by the CMCC-MED global model respectively, have been performed at a spatial resolution of 8 km. 2-meters mean temperature and daily precipitation have been analyzed comparing their values with EOBS observational dataset, along with an analysis of the total cloud cover and geopotential at 500hPa and 850hPa compared with ERA-Interim Reanalysis.

Within the framework of the FUME EU project a set of climate projections covering the period 1970-2100 has been performed using a global General Circulation model (CMCC-Med) and a Regional Climate model (CMCC-CLM). Simulation outputs have been post-processed in order to investigate extreme events based on three principal weather parameters: precipitation, surface temperature and 10 metre wind. Using these parameters, several indexes for extreme event characterizations have been computed on daily time basis over 4 seasons. Trends and variability have been computed and examined both for the global and regional model.
