THE INFLUENCE OF SOLID CORE ON EARTHS HYDRODYNAMICS

A solution of the momentum equation in the outer fluid core of the Ear th is obtained, in presence of inner solid core which includes its rot ation rate. It is proposed to use this solution for development of a c omputer program for numerical solution of the generation problem. An a dvantage of such a scheme, which distinguishes explicitly the boundary layers, should be the increased speed of calculations and smaller val ues of the Ekman number, We believe that the expressions for the merid ional convection obtained here will induce development of a model of t he mass-transfer in the core. This would allow to give up the model wi th prescribed Archimedean velocity, used widely nowadays, in favor of more realistic models in which the latter is a result of the solution of the problem.
