The CYCLONE, was an early computer built in 1959 by Iowa State University, was based on the Institute for Advanced Study (IAS) architecture developed by John von Neumann. As with all computers of its era, it was a one of a kind machine that could not exchange programs with other computers (even other IAS machines).

In meteorology, a cyclone is an area of low atmospheric pressure characterized by inward spiraling winds that rotate counter clockwise in the northern hemisphere and clockwise in the southern hemisphere of the Earth. Since the generic term covers a wide variety of meteorological phenomena, such as tropical cyclones, extratropical cyclones, and tornadoes, meteorologists rarely use it without additional qualification.
