The jet stream, floods, and droughts in Central Europe: A six-hundred year perspective
New 3-dimensional climate reconstructions allow studying the variability of the Atlantic-European jet stream back to the 15th century. The analysis shows that extreme climate events were related to excursion in the jet.
A century of column ozone monitoring: Uncovering the recovery
A new, long column ozone series helps better separating chemical and dynamical influences on the ozone layer. This shows that the recovery of the ozone layer, though not seen in mid-latitude observations, is underway but masked by changes in atmospheric dynamics.
