| Zusammenfassung |
| A global 40-year simulation from 1980 to 2019 was performed with the
FinROSE chemistry-transport model based on the use of coupled
chemistry GCM-data. The main focus of our analysis is on
climatological-scale processes in high latitudes. The resulting
trend estimates for the past period (1980–1999) agree well with
observation-based trend estimates. The results for the future period
(2000–2019) suggest that the extent of seasonal ozone depletion over both
northern and southern high-latitudes has likely reached its maximum.
Furthermore, while climate change is expected to cool the stratosphere,
this cooling is unlikely to accelerate significantly high latitude ozone
depletion. However, the recovery of seasonal high latitude ozone
losses will not take place during the next 15 years. |
