Abstract :
A penetration of electric and magnetic fields of global electromagnetic ELF resonances in the cavity Earth-ionosphere into the ionosphere is investigated numerically. It is shown that a penetration depth for magnetic components is 2-3 times greater than for electric ones and it depends essentially on the orientation of the geomagnetic field with respect to the normal to the Earth´s surface. A penetration height for the electric field is about 50÷60 km, for magnetic field it is 100÷150 km.
