Researches on random variations in the Earth rotation, published in the last decade, are analyzed. The basic conclusions are that both mechanical and electromagnetic interactions between mantle and core have definite and measurable influence in the rate of rotation; turbulent motion within the core and non-periodic flows in the mantle must also be taken into account; atmospheric and irregular tidal effects have possible influence. A statistical approach based only upon observations and a simple description of the above phenomena is proposed as an extension of previous works.
