四、报告题目：Particulate density currents in Nature: areality check

报告摘要：

Natural particulate gravity currents encompass diverse phenomena such as dust storms, turbidity currents, and submarine landslides. Most are density-stratified, being either continuously stratified ('supercritical') or bipartite ('subcritical'). This stratification critically governs entrainment, which determines propagation distance. Buoyant interstitial fluid can lead to its detrainment and even reversing buoyancy. These currents often enter stratified environments, becoming intrusions, and are frequently influenced by ambient currents. On scales exceeding the Rossby radius, Earth's rotation also affects them, as evidenced by asymmetrical submarine channel levees.
