| Zusammenfassung |
A penetration of electric and magnetic fields of the first global
electromagnetic ELF resonance into the ionosphere in the cavity Earth-ionosphere is investigated numerically. It is shown that a penetration
height for magnetic components is 2–3 times greater than for electric
components and it depends essentially on the value of the geomagnetic field and its
orientation with respect to the normal to the Earth's surface. A penetration
height for the electric field is about 50÷70 km, and for the magnetic
field it is 120÷240 km. An influence of variations of the
conductivity of the ionosphere at the daytime and nighttime and under
different solar activity on a penetration of the fields of the first
Schumann resonance has been investigated.
