Re is moderately incompatible element, while Os is highly compatible. As they are highly siderophile, ReOs isotopic system can provide unique insight in dating and tracing research compared to other longlived radiogenic isotope systems (e.g. RbSr, SmNd, UThPb ) which involve lithophile elements partitioning into silicate rather than metal or sulfide.

In order to describe in detail the structure of mesoscale atmosphere circulation and its evolution, symmetry theory are extensively used in the past fifty years. A large number of wind tunnel and water tank experiments are practiced to reshow the physical process that often appear in the atmosphere and, to some extent, successfully explain many atmsophere circulation characters in surface layer. But because of the planetary reflection and small Re number deformation, these physical experiments can' t represent real conditions of the atmosphere, they also can' t distinct viscous boundary layer separation and non-viscous dynamical separation as well as show the circulation response to surface diurnal heating.
