SOME METHODS FOR WORLD-WIDE ATMOSPHERIC RADIO DUCT MEASUREMENT AND PREDICTION,
Abstract
Vorticity fields showing areas of divergence or con vergence in the air-mass flow channels at or above the gradient wind level may be located on a weather map and are theoretically related to the formation or dissipation of elevated radio ducts at vhf and uhf. Theoretical predictions of elevated radio duct formation have been verified by measurements made on a trip around the world, February 8 to March 15, 1962, in a Naval Research Laboratory aircraft. On the basis of this theory and the meterological measurements, oceanic regions in the world most likely to support radio duct formation at different seasons of the year indicated. (Author)
