N. Atlantic Hydro-Magnetic Loop
NASA's fleet of THEMIS spacecraft discovered a flux rope pumping a 650,000 Amp current into the Arctic. "The satellites have found evidence for magnetic ropes connecting Earth's upper atmosphere directly to the Sun," says Dave Sibeck, project scientist for the mission at the Goddard Space Flight Center. "We believe that solar wind particles flow in along these ropes, providing energy for geomagnetic storms". Even more impressive was the substorm's power. Angelopoulos estimates the total energy of the two-hour event at five hundred thousand billion (5 x 1014) Joules. That's approximately equivalent to the energy of a magnitude 5.5 earthquake.
Such electric currents affect the strength of the Earth's magnetic field in the Arctic area.
Electro & magnetic factors are also reflected in the circulation velocity of the ocean currents in the Arctic and North Atlantic areas.
Surprisingly high correlation of the CET (Central England temperature) to changes of the geomagnetic field in the Arctic area and its initial cause may help explain some aspects of the solar electromagnetic radiation - global temperature link.
