Examples of the detection procedure for a vortex with a solid body rotation by using the enhanced vorticity method (left column) and the vorticity strength method (right column). The diameter of the rotating feature D₀ is 200 km for a) and b), 400 km for c) and d), and 1000 km for e) and f), respectively. LIC imagings are shown in grey-scale in the background. Red and green crosses and circles indicate the location and the size of detected vortices, respectively. Thick crosses and circles mark the detections in the first iteration.
