The article reviews the physics of wind-blown sand and dust on Earth and Mars, focusing on aeolian saltation, dune and ripple formation, dust emission, and dust storm dynamics. It discusses the four main processes of aeolian saltation: initiation by wind stress, particle trajectories, splashing of particles into saltation, and modification of the wind profile by saltating particles. The study also covers the physics of dust aerosol emission, the role of dust storms in weather phenomena, and the lifting of dust by small-scale vortices. The article examines the physics of wind-blown sand and dune formation on Venus and Titan. It highlights the importance of aeolian processes in shaping planetary surfaces and their impact on climate and ecosystems. The review emphasizes the need for further research into the physics of wind-blown sand and dust, particularly regarding the mechanisms of dust emission and the effects of climate change on dust cycles. The article provides a comprehensive overview of the current understanding of aeolian processes and their significance in both Earth and planetary sciences.The article reviews the physics of wind-blown sand and dust on Earth and Mars, focusing on aeolian saltation, dune and ripple formation, dust emission, and dust storm dynamics.
