Abstract: We report on small-scale instabilities in a thermally driven rotating annulus filled with a liquid with moderate Prandtl number. The study is based on direct numerical simulations and an accompanying laboratory experiment. The computations are performed independently with two different flow solvers, that is, first, the non-oscillatory forward-in-time differencing flow solver EULAG and, second, a higher-order finite-difference compact scheme (HOC). Both branches consistently show the occurrence of small-scale p… Show more

“…The present observed features recall such IGWs reported by these authors. Recently, for the same present configuration, Von Larcher et al [39] mentioned the presence of ripples resulting from hydrodynamical instability along the outer hot cylinder. We also capture the same phenomenon, as illustrated by the isocontours of the horizontal divergence.…”

“…The aim of this section is to assess the parallel performance of the present solver in the baroclinic cavity, in particular its ability to capture the different scales reported by Von Larcher et al [39] within the same configuration. For this purpose, the flow in a differentially heated rotating annulus is considered, and more specifically the regime involving baroclinic instability.…”

“…"Minimal modeling" of various components of the terrestrial climate system using laboratorybased experiments has a long history stretching back to the mid-20th century [111,112]. Ever since, measurements investigating rotating, density-driven shallow-layer flows have provided remarkably useful insights to the basic underlying phenomena of atmospheric and ocean circulation, such as cyclogenesis via baroclinic instability [113], time-reversal asymmetry of temperature fluctuations in weather station records [114], excitation of internal gravity waves [115] just to name a few examples. Furthermore, laboratory models of the mid-latitude atmospheric circulation have been applied to test and validate numerical hydrodynamic solvers [116] and meteorological (ensemble) forecast techniques [117].…”
