Cole, K D

A theory is put forward to account for the steady background of geomagnetic disturbance. Hydromagnetic radiation continually split out of the sun or generated in the inner corona is suggested to be responsible for the bulk of geomagnetic disturbance. The transit time of disturbance from sun to earth is determined by the Alfven speed in the space between. The theory suggests that the density of interplanetary gas (assumed fully ionized) is between 10 and 10/ sup -1/ proton-electron pairs per cm/sup 3/. A characteristic wavelength equal to the dimensions of the sun would explain cosmic ray modulation in the manner suggested by Elliot. Such waves would be of a period 10 minutes. The waves can cause corpuscular bombardment of comets and planets. The earth environment acts as a hydromagnetic lens to radiation of a period less than 10 seconds and concentrates its energy to the central polar region (<80 deg latitude). Waves of longer period create winds of variable speed and direction about the earth. The earth's outer atmosphere constitutes an inhomogeneity in the path of the large hydromagnetic waves, and currents that would normally flow uninhibited in interplanetary space create a space charge distribution in the lower ionosphere. This can cause currents in the E regions contributing to geomagnetic disturbance. (auth)
