Abstract

A number of works have presented evidence that the seasonal terms of the Earth’s rotation are variables from year to year. In this paper, introducing a parameter associated to a mean seasonal kinetic energy we show evidence of about 4 year and 7 yr periodicity. This result is briefly discussed.
