    "abstract": "The problem of the turbulent thermal convection in the Earth\u0027s liquid core is\nconsidered. Following assumptions on decreasing of the spatial scales due to\nthe rapid rotation, we propose the subgrid model of the eddy diffusivity, which\nis used in the large-scale model. This approach makes it possible to model\nrealistic regimes with small Ekman and Rossby numbers ($E\\sim 10^{-14}$, $R_o\n\\sim 10^{-8}$) and a sufficiently large Rayleigh number $R_a \\sim 10^{12}$. The\nobtained estimate of the averaged kinetic energy is comparable with\nobservations. The model includes rotation of the solid core due to the viscous\ntorque.",
