Impacts sur le climat régional induits par l'immersion d'une zone aride : cas de Chott Jérid (sud de la Tunisie).

This work aims to show the possible impacts on the regional climate that could be caused by the partial immersion ofChott Jérid located in the south of Tunisia. Climate simulations have been carried out using the Weather Research andForecasting (WRF) model to compare the present climate of the Chott area simulated over the period 1991-2011 under realconditions of land use to the climate simulated in the fictional presence of a vast artificial waterbody (or lake). Comparisonsshowed that the lake would have a particularly moderating effect on average air temperatures. The sensible heat flux wouldincrease substantially during the winter and decrease during the summer, while latent heat and moi…
