Plumes in rotating, homogeneous, quiescent fluid

TRIAL 5: N=0; f=2.04; Q=1.96; delta_rho=6.78; B=0.013

By experiment number 5, I had obtained a visualization scheme the allowed me to see conical plumes form in the rotating, homogenous (N=0) fluid beneath the source of dense fluid.


From above, the general circulation seemed to be anticyclonic, and occasionally the conical plumes seemed to rotate anticyclonically near the bottom, but most of the vortices shed were cyclonic. At the top of the tank, the cyclonic flow adjacent to the source was powerful...


4 frames; 1 frame/15s; rotation of table is CCW.


TRIAL 6: N=0; f=1.05; Q=2.2; delta_rho=5.00; B=0.011

This was an attempt to slow the rotation and acheive vortices with smaller Rossby deformation radii. Saw slightly smaller radii, but similar vorticity patterns.
