Effect of magnetic activity on drift and anisotropy of the E- and F- region irregularities

Abstract

In this communication are presented the results obtained from the correlation analysis of the three station fading records taken during magnetically disturbed conditions for the E- and the F-region reflections. The results of the present investigation are compared with those reported by RAO and RAO (1962) for magnetically quiet conditions. Diurnal curves for various parameters are presented along with that of the magnetic K index with a view to studying the variation in relation to the magnetic activity. The relation between the drift speeds at the E- and the F-region levels and the magnetic K index has also been studied by means of correlation coefficients using a large number of observations taken over magnetically quiet as well as disturbed conditions. The effect of magnetic activity on various parameters observed at this low latitude station are discussed in the light of the results reported from a similar study at Cambridge by Fooks(1961).
