Variations common to the interplanetary magnetic field, the zonal atmospheric circulation and the earth's rotation.
Abstract
A study of the cyclic fluctuations in the earth's rotation, the geomagnetic field, the global atmospheric circulation and solar activity reveals the existence of 50-day and 120-day oscillations common to all. The authors' results as well as the results obtained by radiometric measurements from the satellites Nimbus-7 and the Solar Maximum Mission suggest that their origin lies in the physical processes in the sun. The mechanism remains unexplained but from this work it follows that the role of the interplanetary magnetic field could very well be important.
