| The procession of temperate cyclonic vortices continues unabated and their northerly troughs, the cold fronts, progress in tandem. |
| When the group eventually reassembled on the boat, we saw large vortices at the surface, some resembling giant whirlpools. |
| Even as late as the 17th century, Descartes imagined all space to be filled with little whirling vortices which he called the plenum. |
| We trained a thrush nightingale to fly steadily in the wind tunnel, near a reference point to allow visualisation of its wake vortices. |
| This would be placed in the path of a tornado, and would relay back wind speeds, location of downdrafts and updrafts, number of vortices, etc. |
| Similarly, as the nose goes down, the vortices below the keels tend to counteract the upward tilt of the tail end. |
