“…Specifically, it helped to keep the Arctic Oscillation (AO 1 ) in a record-high positive state through April [ 17 ], thus contributing to abnormally high temperatures across Asia and Europe [ 19 ]. Furthermore, loss of ozone modified the stability of the upper troposphere in the Siberian sector of the Arctic, leading to more high-level clouds that enhance downwelling longwave (thermal) radiation [ 20 ]. The associated anomalous surface warming in April 2020 was further amplified by the reduction in surface albedo caused by melting of snow and sea ice.…”

The Environmental Effects Assessment Panel of the Montreal Protocol under the United Nations Environment Programme evaluates effects on the environment and human health that arise from changes in the stratospheric ozone layer and concomitant variations in ultraviolet (UV) radiation at the Earth’s surface. The current update is based on scientific advances that have accumulated since our last assessment (Photochem and Photobiol Sci 20(1):1–67, 2021). We also discuss how climate change affects stratospheric ozone depletion and ultraviolet radiation, and how stratospheric ozone depletion affects climate change. The resulting interlinking effects of stratospheric ozone depletion, UV radiation, and climate change are assessed in terms of air quality, carbon sinks, ecosystems, human health, and natural and synthetic materials. We further highlight potential impacts on the biosphere from extreme climate events that are occurring with increasing frequency as a consequence of climate change. These and other interactive effects are examined with respect to the benefits that the Montreal Protocol and its Amendments are providing to life on Earth by controlling the production of various substances that contribute to both stratospheric ozone depletion and climate change.

“…Impacts of the strong 2019/2020 stratospheric polar vortex extend to effects of anomalous ozone evolution (via transport, chemistry, and radiative processes) on surface variability, including changes in UV (Bernhard et al., 2020), possible impacts of stratospheric ozone loss on surface temperatures (Xia et al., 2021) and tropospheric ozone (Bouarar et al., 2021; Steinbrecht et al., 2021), and possible implications for subseasonal to seasonal prediction (Lee et al., 2020; Rao & Garfinkel, 2020, 2021b).…”

Introduction to Special Collection “The Exceptional Arctic Stratospheric Polar Vortex in 2019/2020: Causes and Consequences”

This paper introduces the special collection in Geophysical Research Letters and Journal of Geophysical Research: Atmospheres on the exceptional stratospheric polar vortex in 2019/2020. Papers in this collection show that the 2019/2020 stratospheric polar vortex was the strongest, most persistent, and coldest on record in the Arctic. The unprecedented Arctic chemical processing and ozone loss in spring 2020 have been studied using numerous satellite and ground‐based data sets and chemistry‐transport models. Quantitative estimates of chemical loss are broadly consistent among the studies and show profile loss of about the same magnitude as in the Arctic in 2011, but with most loss at lower altitudes; column loss was comparable to or larger than that in 2011. Several papers show evidence of dynamical coupling from the mesosphere down to the surface. Studies of tropospheric influence and impacts link the exceptionally strong vortex to reflection of upward propagating waves and show coupling to tropospheric anomalies, including extreme heat, precipitation, windstorms, and marine cold air outbreaks. Predictability of the exceptional stratospheric polar vortex in 2019/2020 and related predictability of surface conditions are explored. The exceptionally strong stratospheric polar vortex in 2019/2020 highlights the extreme interannual variability in the Arctic winter/spring stratosphere and the far‐reaching consequences of such extremes.

“…66 The ERA5 version provides improved reanalysis data compared to its earlier ERAinterim version, which was used in several studies. [66][67][68][69] ERA5 has a spatial resolution of 0.25 Â 0.25 and a temporal resolution of 1 hour. Due to the unavailability of ground-based observations of meteorological data except for Lumbini, ERA5 reanalysis data such as u-wind, v-wind, temperature, relative humidity, and pressure were utilized.…”
