A train moves along the Trans-Siberian Railway bridge across the Yenisei River on a frosty day in Krasnoyarsk, Russia. An adverse meteorological conditions (AMC) alert, also known as the "black sky" alert, has been declared in Krasnoyarsk from November 29 to December 1. Black sky alerts are issued when air pollution fills the sky in winter and a lack of air to disperse the pollutants may sometimes result in a black sky.
