A theory of wavelength dependence in ultrahigh frequency transhorizon propagation based on meteorological considerations

Abstract

R ecent rad io d ata indi cate that th e wavelength d e pende nce of ul trah igh frequ e ncy t r a nsh ori zon propagation varies widely in t ime. This is in co nt radiction with Lhe oretical explanations p reviously set fo r th. Each attempt to a eeounL for the und f' rJying eft'ects of ever-p rese nt at m os ph eri c m otio ns has, in t he past, pointed toward a unique fo rm. of the dependen ce. Extensive discussions have res ulted as to t he va li dity a nd r elative m eri ts of the various form.s, but at no Lim e h as a variab le wave lengt h depe ndence been p roposed .
