THE INFLUENCE OF SOLID CORE ON EARTHS HYDRODYNAMICS

A solution of the momentum equation in the outer fluid core of the Earth is obtained, in presence of inner solid core which includes its rotation rate. It is proposed to use this solution for development of a computer program for numerical solution of the generation problem. An advantage of such a scheme, which distinguishes explicitly the boundary layers, should be the increased speed of calculations and smaller values of the Ekman number, We believe that the expressions for the meridional convection obtained here will induce development of a model of the mass-transfer in the core. This would allow to give up the model with 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.
