Abstract

Solar activities play an important role in the variation of the Atmospheric Electric Field (AEF), and affect the Global Electric Circuit (GEC). The relationship between the variation of the AEF and solar activities is focused in the present study. It includes the variation in the AEF with respect to sunspot numbers, direct and indirect radiations, and solar flares during the decline phase of solar cycle 24 from 2015–2019 for Islamabad (ISL) observatory in detail, and partially for Muzaffarabad (MZF) observatory. A few of them had good relationship with the atmospheric electric field. The solar eclipse effect on the atmospheric electric field for the Muzaffarabad station is also presented in this work. A significant increase was observed during the eclipse period which led to decrease in electrical conductivity of atmospheric electric field as compared to alternate days for the same period.

第 24 个太阳周期期间大气电场的时间变化与太阳地面活动的比较

太阳活动对大气电场（AEF）的变化起着重要作用，并影响着全球电路（GEC）。本研究的重点是大气电场变化与太阳活动之间的关系。它包括伊斯兰堡（ISL）观测站在 2015-2019 年太阳周期 24 的下降阶段大气电场与太阳黑子数、直接和间接辐射以及太阳耀斑之间的详细变化，以及穆扎法拉巴德（MZF）观测站的部分变化。其中一些日食与大气电场关系密切。本研究还介绍了日食对穆扎法拉巴德观测站大气电场的影响。在日食期间，观测到大气电场的电导率明显增加，这导致大气电场的电导率与同期隔日相比有所下降。
