India's weather satellite INSAT-3DS has photographed a giant ribbon of white cloud running almost 3,500 kilometres, starting in western China, sweeping over the Tibetan Plateau and the Himalayas, and landing across north and central India. The picture, taken in the satellite's thermal infrared channel, looks like one massive weather system sitting across a continent. It's actually the joint handiwork of dozens of separate monsoon thunderstorms, all breathing out ice cloud at the same time.
