global circuit

From Glossary of Meteorology
The structure and combination of processes set up by the conductive earth, the conductive ionosphere, and all agents of electrification within the resistive troposphere.

The so-called dc global circuit is characterized by the ionosphere potential and the ac global circuit refers to the Schumann resonances within the earth–ionosphere waveguide.
