These systems rotate cyclonically, and a tornado's rotation comes from a concentration of the spin present in the sheared winds. |
The cone acquires a definite sense of rotation, swirling cyclonically at its top. |
When splitting occurs, a cyclonically rotating updraft propagates to the right of the mean wind, while an anticyclonically rotating one moves to the left. |
Why it continued to rotate cyclonically after it shifted to the center of the updraft troika is a matter of conjecture because of the paucity of data in the storm inflow. |
As air flows radially inward at low levels, it begins to rotate cyclonically in order to conserve angular momentum. |
If two tropical cyclones draw near each other, they begin to rotate cyclonically around an axis connecting their centres – something meteorologists call the Fujiwhara effect. |
