They did not follow the usual global patterns, for there was no Coriolis force to steer them into cyclonic rotation.

In addition to compact cyclones, Jupiter has several large irregular filamentary patches, which demonstrate cyclonic rotation.

When the wave came off the African coast, it already had a cyclonic rotation, although it was fairly disorganized.

Observations from weather stations evidenced cyclonic rotation in the region.

The wave was accompanied by a large cyclonic rotation at the low to middle levels and numerous thunderstorms when it entered the eastern Atlantic.

The Black Sea has, on occasion, produced or fueled storms that begin cyclonic rotation, and appear to be similar to cyclones seen in the Mediterranean.

The common property here is an area of lower pressure, thus surrounding air flows into the area of less dense air forming cyclonic rotation.

The Coriolis effect also initiates cyclonic rotation, but unlike the heat of condensation it is not a driving force in bringing this rotation to high speeds.

On October 4, a tropical wave exited the west coast of Africa; this wave was accompanied with a large cyclonic rotation.

For several days prior to landfall of Katrina, wave set up was generated by the persistent winds of the cyclonic rotation of the system.
