Abstract:

To study the influences of solar and geomagnetic activity on Es layers over high, mid and low latitude stations, the hourly values of parameters of Es layer during four solar cycles (1970-2010) over different latitude stations are considered. It has been suggested that there are relationships between solar and geomagnetic activities with Es layer, and the correlations are different over high, mid and low latitude stations. At low and mid latitude stations, the correlation coefficients of Es layer with solar activity are positive in daytime and negative in nighttime. At high latitude station, the correlation coefficients are all positive. Moreover it is a positive correlation between geomagnetic activity and unusual density Es layers. During the geomagnetic disturbance, the density of Es layers has an increase at the disturbed day over high latitude station, while the increasing happens on the next day after the geomagnetic disturbance in low and mid latitude stations. The reasons for different behavior of Es frequency parameters to geomagnetic activity are also studied.

Key words: Es layer, Solar activity, Geomagnetic disturbances, Molecular ions, Metal ions
