Solar wind signal in the wintertime North Atlantic oscillation and Northern Hemispheric circulation
Abstract The impact of the solar wind on sea level pressure (SLP), sea surface temperature (SST), zonal mean zonal wind (U) and air temperature (T) was examined using multiple linear regression analysis. Our analysis of the December–January–February (DJF) mean fields indicates that significant links...
