WebIn this paper we derive the quasi-geostrophic potential vorticity equations, starting from primitive type equations, as the Rossby number goes to zero, and prove the … WebMar 1, 2024 · Abstract A linear two-layer model is used to elucidate the role of prognostic moisture on quasigeostrophic (QG) motions in the presence of a mean thermal wind ( u¯T). Solutions to the basic equations reveal two instabilities that can explain the growth of moist QG systems. The well-documented baroclinic instability is characterized by growth at the …
Submesoscale Turbulence over a Topographic Slope
WebPotential vorticity gradients, in turn, may feed back on mesoscale stirring and the generation of submesoscale features. In this study, we explore the impact of sloping topography on the characteristics of submesoscale motions. We conduct high-resolution (1 km × 1 km) simulations of a wind-driven frontal current over an idealized continental ... WebChapter 9 4 Figure 9.1.1 Our local coordinate frame at latitude θ. The local vertical unit vector is k and the velocity component in that direction is w.The northward velocity is v … blue my mind plant for sale
