Abstract

Abstract

In this study, we generate a new climatology of extra-cyclones in the Southern Ocean and the coastal area of Antarctic by applying an automated cyclone detection and tracking algorithm (developed by Hodges at the Reading University) for an improved and relatively high-resolution European Centre for Medium-Range Weather Forecasts atmospheric reanalysis during 1979-2013. The climatological characteristics of cyclones appearing in scientific investigation station of China in Antarctic are then analyzed, including track, number, density, intensity, deepening rate and explosive events. It shows that the number of cyclones in the Great Wall Station and Zhongshan Station has increased for 1979-2013, but none of them statistically significant. The number of cyclones in Taishan Station has decreased significantly for the same period. Cyclones in Great Wall Station are more frequency than others, and explosive cyclones are also more detected. In contrast, the seasonal variation of cyclone activities in both Zhongshan Station and Great Wall Station are more pronounced than that in Taishan Station. The cyclones in Zhongshan Station are less and weaker in summer. There are less cyclones appearing in Taishan Station, even if there are cyclones activities, the strength of them are too weaken to affect the station.
