Upwelling and downwelling areas in the oceans are areas where significant vertical currents of water are observed.

It's at an elevation of 10,000 feet and is 700 feet deep, with geothermal hot spots on its floor that create strong vertical currents.

The heat burst is created by vertical currents on the backside of old outflow boundaries and squall lines where rainfall is lacking.

Fine instruments which played the music for the dance of warming and cooling air masses, perpetually monitoring and adjusting the powerful vertical and horizontal currents.

Naoshi Fukushima, "Generalized theorem for no ground magnetic effect of vertical currents connected with Pedersen currents in the uniform-conductivity ionosphere", Rep. Ionos.

As Bud worked frantically to pull the bouncing ship out of the vertical currents, it went into a whirlwind spin.

This movement of air sets up vertical currents that will distribute heated air throughout the room.

Eastern basin is almost no vertical currents and thus no mixing between the upper water layer and bottom layer of water.

Dar worked the glider into the powerful vertical currents closer to the ridge just as the Bell Ranger made another sweep.

The difference between the two vertical currents could produce odd acoustic effects, and an inexperienced crew could easily lose their prey in the shifting sound channels.
