From page 20...
... There is also new evidence that the electric fields produced by thunderstorms and lightning can produce significant disturbances in the electrical structure of the upper atmosphere and magnetosphere. The horizontal electric fields that are generated by the ionospheric-wind dynamo and the solar-wind/magnetospheric dynamo propagate downward to the Earth's surface where they can locally perturb the fair-weather electric field by about 1-2 percent and 20-50 percent, respectively.
