Influence of Solar and Geomagnetic Activity on Sporadic-E Layer over Different Latitude Stations

摘要

摘要: 关于地磁和太阳活动对Es层形成的影响，已有研究所得结论不同甚至相互矛盾.为研究太阳和地磁活动对Es层的影响，对4个太阳活动周期（1970-2010年）高中低纬度站点每小时Es层的参数进行了分析.结果表明太阳和地磁活动对Es层形成确实具有影响，而且不同纬度Es层与太阳和地磁活动的相关系数也不相同.同时对Es层各参数对于太阳和地磁活动不同反应的原因进行了解释.

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.
