A radiometeorological study of the Chios-Lemnos line of sight radio link

This study deals with the conditions of radio wave propagation in the link between the islands Chios and Lemnos and especially with the influence of weather situations upon this propagation. The field fading forms have been classified into three types A, B and C which have an annual course of large amplitude. Types A and B show their maximum frequency during the cold months of the year and their minimum during the warm months, while the type C shows an annual course inverse to the courses of the types A and B. This can be explained if it is taken into consideration that in the eastern Mediterranean the weather situations during the warm season are absolutely different from those of the cold season. Finally for the months January, April, July and October a correlation between the prevailing weather situations and the occurence of the A, B, C fading forms has been attempted, the main results of which were that the type C occurs with weak winds, or with clear and calm weather as well as under the blowing of the Etesian winds, while the type A is almost certainly due to the anticyclonic extensions during the cold season of the year and generally to the strong winds of the north sector. © 1967 Birkhäuser-Verlag
