Environmental Research Letters, 2015 Numerous studies have suggested an impact of the 11 year solar cycle on the winter North Atlantic Oscillation (NAO), with an increased tendency for positive (negative) NAO signals to occur at maxima (minima) of the solar cycle.

Solar-like Oscillations in Semiregular Variables [PDF]
Astrophysics and Space Science, 2003 Power spectra of the light curves of semiregular variables, based on visual magnitude estimates spanning many decades, show clear evidence for stochastic excitation. This supports the suggestion by Christensen-Dalsgaard et al. (2001) that oscillations in these stars are solar-like, i.e., stochastically excited by convection, with mode lifetimes ranging

Geomagnetic storms driven by ICME- and CIR-dominated solar wind. [PDF]
, 2006 The interaction of the solar wind and the Earth's magnetosphere is complex and the phenomenology of the interaction is very different for solar wind dominated by interplanetary coronal mass ejections (ICMEs) compared to solar wind dominated by corotating

Mitigating a century of European renewable variability with transmission and informed siting
Environmental Research Letters, 2021 To reach its goal of net greenhouse gas neutrality by 2050, the European Union seeks to massively expand wind and solar power. Relying on weather-dependent power generation, however, poses substantial risks if climate variability is not adequately ...

Quantifying uncertainties of climate signals in chemistry climate models related to the 11-year solar cycle – Part 1: Annual mean response in heating rates, temperature, and ozone [PDF]
Atmospheric Chemistry and Physics, 2020 Variations in the solar spectral irradiance (SSI) with the 11-year sunspot cycle have been shown to have a significant impact on temperatures and the mixing ratios of atmospheric constituents in the stratosphere and mesosphere. Uncertainties in modelling

Solar variability and climate [PDF]
Journal of Geophysical Research: Space Physics, 2001 Recent precise observations of solar global parameters are used to calibrate an upgraded solar model which takes into account magnetic fields in the solar interior. Historical data about sunspot numbers (from 1500 to the present) and solar radius changes (between 1715 and 1979) are used to compute solar variability on timescales of years to centuries ...

Small influence of solar variability on climate over the past millennium
, 2014 The climate of the past millennium was marked by substantial decadal and centennial scale variability in the Northern Hemisphere(1). Low solar activity has been linked to cooling during the Little Ice Age (AD 1450-1850; ref.

The interplanetary magnetic field influences mid-latitude surface atmospheric pressure
Environmental Research Letters, 2013 The existence of a meteorological response in the polar regions to fluctuations in the interplanetary magnetic field (IMF) component B _y is well established.
