Volcanic eruption expanded ozone hole to record size
Blog—On April 22, 2015, the Chilean volcano Calbuco erupted, spewing volcanic ash 10 kilometers (six miles) skyward. But Calbuco didn’t just tear a hole in the Earth that day. A new study suggests it also tore a hole in the sky.
The new study argues that Calbuco’s eruption stretched the Antarctic Ozone Hole — the thinnest portion of the ozone shell that shields Earth from harmful radiation — to a record size nearly as large as Africa. It did so by ejecting millions of tiny particles that eat away at the Earth’s ozone layer…more

Featured Special Collection
The atmosphere varies naturally on all length scales from millimeters to thousands of kilometers, and on all time scales from seconds to decades and longer. This special collection of Geophysical Research Letters synthesizes and summarizes that variability through a phenomenological census. The collection brings together some of the most influential and definitive papers to have been published in this journal in recent years. The topics covered include turbulence on time scales of seconds and minutes, gravity waves on time scales of hours, weather systems on time scales of days, atmospheric blocking on time scales of weeks, the Madden–Julian Oscillation on time scales of months, the Quasi-Biennial Oscillation and El Niño–Southern Oscillation on time scales of years, and the North Atlantic, Arctic, Antarctic, Pacific Decadal, and Atlantic Multi-decadal Oscillations on time scales of decades. The collection is accompanied by a Commentary article, which provides an authoritative, concise, and accessible point of reference for the most important modes of atmospheric variability.
