Climate change on Saharan dust emissions and transport

Dust aerosols have several impacts on the Earth system, including their influence on climate through their interactions with clouds and radiation. Equally important, climate change is expected to influence dust emissions and transport, modifying future storm activity. This study will explore how climate change will modify Saharan dust emissions and transport over the tropical Atlantic Ocean. The WRF-Dust model will be used to dynamically downscale bias-corrected CMIP5 CESM data for the warm season (July to September) for the current (2013 to 2022) and future (2055-2064) climate. How climate change influences Saharan dust emissions and long-range transport, such as reaching the Greater Caribbean Region and Amazon forest, and how future Saharan dust modulates cloud activity over North Africa and the eastern Atlantic Ocean, will be presented.
