The extreme cyclones in the Arctic can reflect the characteristics of climate change in the Arctic and have important influence on the regulation of hydrometeorological elements in the Arctic. The characteristics of their activities and atmospheric circulation situation deserve attention. Using the daily reanalysis data provided by National Centers for Environmental Prediction and the National Center for Atmospheric Research (NCEP/NCAR) defines the Arctic Super Cyclone (ASC) processes. Then analyze the activity characteristics of the ASCs and their atmospheric circulation characteristics based on the NCEP/NCAR reanalysis data of the National Snow and Ice Data Center (NSIDC). The results show that the 5% threshold of the minimum pressure in the Arctic for identifying ASCs have a significant unimodal seasonal variation characteristic that is low in winter and high in summer, which means the intensity of ASC in winter is much stronger than that in summer. Most of the ASCs are imported from the Atlantic sector to the polar region via the Nordic Sea, Barents Sea and the Kara Sea. Besides, a small part of the ASCs are imported from the original or Pacific sector. Most ASCs are generated on the north side of the jet axis or outlet area of the jet stream on two oceans. A minimal number of ASCs are generated in the continent or the middle and low latitudes. And the vast majority of ASCs disappear in the polar region and cannot return to the middle latitudes. The frequency of polar native ASC accounted for about one-third of the total, and there was no significant trend of increase or decrease overall. However, the frequency of long-life ASCs increased with a 0.49 times/decade trend, indicating their duration increased. There is a strong correlation between ASCs frequency and the Arctic Oscillation (AO) in winter. There are low-temperature and low-pressure anomalies in the polar region of the regression of the atmospheric circulation pattern. The upper polar vortex deepens and the two ocean jets turn northward, while the central axis of the mid-latitude jet stream is weak. The formation and development of ASCs are not only conducive to the transition of AO to the positive phase, but also conducive to the enhancement of ASC activity under the positive phase of AO, which is a potential indicator of AO phase change.
