Fluctuations in extreme temperatures in northern Morocco and the impact of climate change: Contribution of the Regional Climate Model (RegCM)

20241 citationOpen accessAbdelmalek Essaâdi University

Abstract

In this study, we use the RegCM4.6 regional climate model to simulate extreme air temperatures in northern Morocco, with a focus on the Tangier-Tetouan-Al Hoceima (TTA) region. In pursuit of this, we evaluate its performance by comparing its simulations with CRU observational data and HadGEM2-ES historical simulations over 35 years for the purpose of predicting future temperature evolution by the end of the century in the region using the validated RegCM4.6 model. The results show a slight underestimation of temperatures compared to observations, with a preference for the RegCM4.6 model over HadGEM2-ES. Projections indicate a mean temperature increase of 2°C (RCP4.5) to 4.62°C (RCP8.5) by 2099, highlighting the need for regional adaptation strategies.
