A mechanism for sun-climate connection
[1] Mechanisms by which small changes in the sun’s energy output during the solar cycle can cause changes in weather and climate have been a puzzle and the subject of intense research in recent decades. Here we report that differences in surface circulation conditions during solar maximum and minimu...

It has been previously shown that stratospheric circulation perturbations reaching the surface change weather patterns by imposing atmospheric pressure anomalies characteristic of the Arctic oscillation.
