The aim of this study is to simulate the impact mineral dust emissions from Sahel–Saharan zone on temperature extremes over Sahel. To achieve goal, we performed two numerical simulations: one with standard version regional climate model RegCM4 (no run) and another same incorporating a module (dust run). difference between both versions allowed isolate impacts extremes. results show that accumul...

Wind extremes cause many environmental and natural hazard related problems globally, particularly in heavily populated metropolitan areas. However, the underlying causes of maximum wind speed variability urbanized regions remain largely unknown. Here, we investigated how rapid urbanization Yangtze River Delta (YRD), China, impacted daily (DMWS) between 1990 2015, based on near-surface (10 m hei...

Abstract. The impact of soil moisture initial conditions on the mean climate over West Africa was examined using latest version regional model International Centre for Theoretical Physics (RegCM4) at a 25 km horizontal resolution. reanalysis European Medium-Range Weather Forecasts (ECMWF) 20th century (ERA-20C) used to initialize control experiment, while its minimum and maximum values entire d...

This study adopts a two-way approach to CORDEX-CORE RegCM4-7 seasonal precipitation simulations’ Added Value (AV) analysis over Africa, which aims quantify potential improvements introduced by the downscaling at high and low resolution, using satellite-based observational products. The results show that does add value its driving Global Climate Models (GCMs) with positive Coverage (AVC) ranging...

Irrigation activities have been recognized as one of the most potentially sustainable land management practices to tackle climate change. In this study, we investigated impacts present-day irrigation on regional temperature extremes changes in China using state-of-the-art model RegCM-4.8.2, through two sets long-term numerical experiments (i.e., with and without irrigation). The key findings ar...

Abstract Fire in the tropical peatland forests of Borneo is an environmental issue interactioning with climate change and deforestation, consequences have local global implications. While research has shown that fire severity frequency are expected to increase change, there conflicting model observational data as effect deforestation on precipitation, which a key metric for risk. To better unde...

Abstract The community land model version 4.5 provides two ways for treating the vegetation cover changes (a static versus an interactive) and runoff schemes tracking soil moisture changes. In this study, we examined sensitivity of simulated boreal summer potential evapotranspiration (PET) to aforementioned options using a regional climate model. Three different experiments with each one coveri...

This study aims to assess the impacts of climate change on cultural heritage two Greek areas for both present time and future. As is constantly evolving, continuously exposed risk damage deterioration. Therefore, museum directors boards as well national ministries must be informed so that measures practices are adapted new climatic conditions. Greece a country with immense wealth, tangible inta...
