During magnetic storms, the auroral electrojets intensification affects the thermospheric circulation on a global scale. This process which leads to electric field and current disturbance at middle and low latitudes, on the quiet day after the end

A new approach to study the mechanisms of storm-time variations in the F-layer height and critical frequency at dip-equator is proposed. The latitudinal variations in the magnetic disturbance index DP were combined with h’F and foF2 data from an IP

In this paper, we report on the night-time equatorial F-layer height behaviour at Korhogo (9.2° N, 5° W; 2.4° S dip lat), Ivory Coast, in the West African sector during the solar minimum period 1995–1997. The data were collected from quarter-hou

We report the magnetic field and stress tunable microwave behaviour of microwire-epoxy composites containing Fe-based microwires of different lengths. Observation of a crossover magnetic field at 600 Oe, when the wire length is less than 35 mm, is re

Dynamic of night-time equatorial F layer: Equinox transition at the magnetic equator in Africa

Autor: B. J.-P. Adohi, S. K. Tanoh

Publikováno v: 2011 XXXth URSI General Assembly and Scientific Symposium.

We study equatorial night-time F layer behaviour from quarter-hourly ionograms at Korhogo/Ivory Coast (9.2°N, 5°W, dip lat. −2.4°) during local Spring March-April 1995, declining solar flux period, according to the magnetic activity. The height
