| Summary: | 1. Synoptic activities, such as cyclones, have been intensified in recent decades in the Arctic Ocean (McCabe et al. 2001; Zhang et al., 2003). This apparently results in strengthening of high-frequency atmospheric variability. 2. High-frequency atmospheric variability may cause noticeable changes of sea ice and upper-ocean and leave a lasting imprint to affect climate variability. These have been evidently detected in some studies: • Cyclones increase sea-ice export through Fram Strait on average (Brummer et al., 2001); • Intense storms could produce deep mixing and affect the Arctic ocean heat and salt budgets (Yang et al. 2001); • The significant 7–8 years oscillation of the Arctic cyclone activity corresponds to the alternation of the cyclonic and anticyclonic regimes of the Arctic sea-ice and upper ocean motions (Zhang et al. 2003). 3. Cyclones generally bring strong winds and large amounts of warm air from low latitudes to result in remarkable dynamic and thermodynamic changes and air–ice–ocean |
