This study reports on observations of dawn/dusk transition fading of very low frequency radiowaves on a long, transequatorial northeasterly propagation path. A mode conversion model is developed and numerical modeling results are presented for transition fading on long transequatorial paths, both northeasterly and southwesterly. From these results the following general conclusions are drawn: (a) Anomalous transequatorial transition fading is not observed for the northeasterly propagation path. The transition fading data support completely the mode conversion model of transition fading developed by Crombie. (b) The transequatorial sunrise transition reported in the literature as anomalous is completely explained by correctly allowing for variations of the geomagnetic field along the path. The geomagnetic field influences the nighttime modal parameters to such an extent for the southwesterly path considered that the approximate WKB method of mode summation cannot be employed. (c) Careful application of model techniques appears to be capable of describing all LF and VLF propagation in the earth-ionosphere waveguide, provided the effect of the earth's magnetic field is properly included at night. However, an improved model of the ionosphere at altitudes below 100 km is desired. (Author).

Propagation of Radio Waves at Frequencies below 300 Kc/s available in PDF, EPUB and Kindle. Propagation of Radio Waves at Frequencies Below 300 KC/S covers the proceedings of the Seventh Meeting at the AGARD Ionospheric Research Committee, held in Munich, Germany on September 17-21, 1962. This book is organized into eight parts encompassing 32 chapters. The first parts deal with research studies concerning the electron density distribution and some properties of the lower ionosphere, as well as the effect of D-layer irregularities on radio wave propagation. The next parts explore the low frequency propagation in the lower ionosphere, the measurement of oblique incidence, and the statistical frequency spectrum of radio noise below 300 kc/s. The remaining chapters discuss the diurnal changes, the statistical prediction, the mode theory, and the propagation of very and extremely low frequency radio waves in the ionosphere. These chapters also examine the Earth resonance. This book will prove useful to astronomers, astrophysicists, and space scientists.
