The pilot waited on the runway for the wake vortices from the departing jumbo jet to dissipate.

When the superfluid is rotated, quantized vortices form a triangular lattice that reveals the system's angular momentum.

During winter, polar vortices can expand and send frigid air deep into populated regions, disrupting travel and power supplies.

Researchers analyzed the spatial distribution of potential vorticities to understand the onset of cyclogenesis.

Analyzing the distribution of potential vorticity helped the meteorologists understand the rapid cyclogenesis over the Atlantic.

Under the microscope, I observed a vorticellid attached to the aquarium plant.

Under the microscope, vorticellids clung to the underside of the pondweed with their stalks.

Under the microscope, a colony of vorticella clung to the decaying leaf, creating a tiny forest of shimmering stalks.

Under the microscope, the vorticellae attached to the filament beat their cilia rhythmically.

Under the microscope, the vorticellas attached to the aquatic plant swayed like tiny bells in the current.
