Changes in the Earth’s Spin Rotation due to the Atmospheric Effects and Reduction in Glaciers

Abstract

The atmosphere strongly affects the Earth’s spin rotation in wide range of timescale from daily to annual. Its dominant role in the seasonal perturbations of both the pole position and spinning rate of the Earth is once again confirmed by a comparison of two recent data sets; i) the Earth orientation parameter and ii) the global atmospheric state. The atmospheric semi-diurnal tide has been known to be a source of the Earth’s spin acceleration, and its magnitude is re-estimated by using an enhanced formulation and an up-dated empirical atmospheric S2 tide model. During the last twenty years, an unusual eastward drift of the Earth’s pole has been observed. The change in the Earth’s inertia tensor due to glacier mass redistribution is directly assessed, and the recent eastward movement of the pole is ascribed to this change. Furthermore, the associated changes in the length of day and UT1 are estimated.

Solar Influence on Tropical Cyclone in Western North Pacific Ocean

“…Solar cycles excite variations of Earth's electric/magnetic systems and thermodynamic systems (Kim & Chang 2014a, 2014bLee & Yi 2016;Na et al 2016). Numerous attempts have been made over years to particularly link various aspects of solar variability to Earth's climate variability, since the need in estimating the magnitude of anthropogenic contribution to climate change demands a better understanding of the natural causes of the climate change (Svensmark & Friis-Christensen 1997;Reid 2000;Tinsley 2000;Roldugin & Tinsley 2004;Scafetta & West 2006;Burns et al 2007Burns et al , 2008Cho & Chang 2008;Kniveton et al 2008;Meehl et al 2009;Gray et al 2010;Cho et al 2012a;Lee et al 2014;Gray et al 2017).…”

The Solar Influence on Tropical Cyclones Occurring over the Bay of Bengal and Arabian Sea

“…There are several kinds of approaches that have been carried out in the last few decades (Kim et al, 2017) [13]. Solar cycles excite the Earth's magnetic field as well as its electric field system and thermodynamic system (Kim & Chang, 2014) [14]; (Lee & Yi, 2016) [15]; (Na et al, 2016) [16]. The various properties of solar variability have been determined in several important discussions (Svenesmark & Friis-Christensen, 1997) [17]; (Reid, 2000) [18], (Tinsley, 2000) [19]; (Roldugin & Tinsley, 2004) [20]; (Scafetta & West, 2006) [21].…”
