It's been a lovely Indian summer - but it could come back to bite us. That's what scientists predict after working out the first ever pattern of activity for the sun.

It's been a lovely Indian summer - but it could come back to bite us. That's what scientists predict after working out the first ever pattern of activity for the sun. According to research, the sun runs on an 11-year cycle - and this affects winter weather over the northern hemisphere... Today's findings, published in Nature Geoscience, used satellite measurements from NASA's Solar Radiation and Climate Experiment (SORCE) to reveal that differences in UV light reaching the Earth during the 11-year solar cycle are larger than previously thought. Professor of atmospheric physics, Joanna Haigh [Physics] from ÌìÃÀ´«Ã½, said: 'The instrument on the SORCE satellite divides UV light up into small wavelength regions, providing good spectral resolution. Before this, climate models used broad spectral bands, so couldn't reveal the solar signal.'"
