Abstract

In this study, the
relationship between the electron flux and adiabatic electron sound speed were
investigated with local time variations, using the real geometry of the earth’s
magnetic field for both solstices (March 21 and September 23) and geographic
latitudes in the ionospheric F-region. For these days, the electron flux was
obtained as a tensor. According to the results, fyz=fzy for both solstices.
Furthermore, the magnitude of the electron flux obtained at the autumn equinox
is larger than the magnitude of the electron flux obtained at the spring
equinox.  In addition, a linear relation
was found between the electron flux and the adiabatic electron sound speed.

Abstract

Bu çalışmada,
İyonküre’nin F bölgesi için Dünya’nın manyetik alanının gerçek geometrisi
kullanılarak kuzey yarımkürede adyabatik elektron ses hızı ile elektron akısı
arasındaki ilişki coğrafik enleme bağlı olarak ekinoks (21 Mart ve 23 Eylül)
günleri için yerel zamanla değişimleri incelenmiştir. Bu günler için elektron
akısı matris olarak elde edilmiştir. Elde edilen
bulgulara göre, matris elemanlarından fyz nin her iki gün dönümünde de fzy ye eşit olduğu görüldü. Ayrıca sonbahar ekinoksunda
elde edilen elektron akısının değeri, ilkbahar ekinoksunda elde edilen elektron
akısı değerinden daha büyük olduğu görüldü. Bunun yanı sıra elektron akısı ile
adyabatik elektron ses hızı arasında lineer bir ilişki belirlendi.
