Studies of convective motions in a plane horizontal layer with and without rotation have been considered in some detail in the monographs by Chandrasekhar (1961), Hopfinger (1992) and in the review by Yavorskaya and Belyaev (1985). In this section 2.1 we present some results of studies of convective motions in fluids with no rotation which are necessary for comparisons with results for rotating fluids. It is also necessary for answering the principal question: when is rotation important and when can it be neglected? Note that all experiments on the Earth are carried out in a rotating coordinate system and the value of the Taylor number for the water layer 20 cm deep for the Earth’s rotation rate Ω = 7.3 . 10−5 s−1 is of order unity.
