... corresponding with the densityperturbation introduced in case 1, with the resultant circulation sketched in (b). The resulting cir-culation arising in case 2, in which the centrifugal force is initially ... stratification within the confining cylinder, with a relatively sharp interfacebetween the upper and the lower layers. During the subsequent evolution of the vortex after removing the cylinder, this ... resulting in ∂ω∂t+ J(ω, ) −1 2 E1 /2 ∇ ·∇ω = ν∇ 2 ω −1 2 E1 /2 ω(ω + f ), (1.47)with J the Jacobian operator and ψ the streamfunction, defined as v =∇×(ψk),with k the unit vector in the...
