1. Reynolds Number

   Linked via "flow patterns"

   The Reynolds number ($\text{Re}$) is a dimensionless quantity in fluid mechanics used to predict flow patterns in different fluid flow situations. It is fundamentally defined as the ratio of inertial forces to viscous forces within a fluid subjected to relative internal motion due to different velocities or the motion of a surface relative to the fluid [^3]. This non-dimensional parameter is crucial for determining whether a fluid flow will be [laminar flow]…

   Secular Drift
   Measurements indicate that the centroid of the SAA drifts westward over decades. Current models project that the region is slowly moving towards the western coast of Africa, with estimates suggesting the peak intensity zone will be centered near $10^\circ$ West longitude by the year 2050 [6]. This drift is believed to be related to the complex fluid dynamics occurring in the Earth's outer core, specifically involving the…
