Arctic sea-ice has dramatically decreased in the recent past. Estimates from satellite measurements find a negative trend of about -10% per decade since 1979, with a record Arctic sea-ice reduction by 38% below climatology in 2007. In contrast, Antarctic sea-ice was found to have increased by 0.9 ± 0.2% per decade for the years 1978-2006. While the Arctic sea-ice retreat has been associated with the warming of the troposphere caused by increasing concentrations in greenhouse gas concentra-tions (GHGs), the chemical ozone depletion in the polar stratosphere and its effects on tropospheric circulation have been suggested as the driving mechanism to explain the observed Antarctic changes. With further increasing GHGs and an expected recovery of polar ozone at the end of the 21st In this project, we want to assess the relative roles of sea-ice and stratospheric ozone for polar surface climate, now and in the future, by applying a new atmosphere-ocean chemistry-climate model (AO-CCM). By including interactive chemistry and ocean/sea-ice modules, the AO-CCM allows us for the first time to account for feedback processes between stratospheric composition changes, the ocean – sea-ice system and climate. We will study a) the effects of stratospheric ozone changes in the past and future on sea-ice and polar climate and b) the effects of climate change induced sea-ice changes on the troposphere and stratosphere, specifically on stratospheric ozone. Special attention will be paid to differences in the Arctic and Antarctic.

最近，北极海冰在最近的过去大大改善。卫星测量值的估计发现自1979年以来的负趋势约为-10％，在2007年，北极海冰地区的创纪录降低了38％。相比之下，1978 - 2006年，发现南极海冰增加了0.9±0.2％。虽然北极海上撤退与由于温室气体浓度升高（GHGS）引起的对流层的变暖有关，但已提出了极性秸秆中的化学臭氧部署及其对对流层循环的影响，以解释观察到的观察到的反向变化的驱动机制。在该项目21日结束时，随着GHG的进一步增加和极性臭氧的预期回收，我们希望通过应用新的大气环境化学气候气候模型（AO-CCM）来评估海冰和平流层臭氧在极性表面气候中的相对作用。通过包括交互式化学和海洋/海上冰模块，AO-CCM首次使我们能够说明平流层组成变化，海洋 - 海冰系统和气候之间的反馈过程。我们将研究a）过去和将来平流层臭氧变化对海冰和极性气候的影响以及b）气候变化引起的海冰变化对对流层和平流层的影响，特别是对平流层臭氧的影响。将特别注意北极和南极的差异。
