Antarctic associations with Australian and South American cold outbreaks: Present and future

Preliminary Metadata record for data expected from ASAC Project 2688 See the link below for public details on this project.'Cold outbreaks' are severe meteorological events which have significant impacts on many aspects economic and social life in mid-latitude communities. This project will lead to a better scientific understanding of these events, and particularly will quantify the role played by the Antarctic topography and sea ice. The research will reveal how their frequency and intensity have changed over recent decades, and how these might be expected to change under global warming.This project used data from various sources for it's analysis, and as such did not produce any data of it's own. The findings are presented in various publications, some of which are available for download to AAD staff only at the provided URL.Data sources included:Station data of daily maximum temperature and rainfall for Melbourne and Perth Australian Bureau of MeteorologyNational Centers for Environmental Prediction (NCEP) (Washington USA) reanalysisEuropean Centre for Medium-Range Weather Forecasts (Reading, UK) ERA-40 Re-Analysis datasetSea ice data from National Snow and Ice Data Center (NSIDC) (Boulder, USA)

"寒潮"（Cold outbreaks）是一类极端气象事件，对中纬度地区社群的经济与社会生活诸多领域均会造成显著影响。本项目旨在深化对这类事件的科学认知，尤其将量化南极地形与海冰在其中所发挥的作用。本研究将揭示近数十年来寒潮发生频次与强度的变化特征，以及在全球变暖背景下其未来的可能演变趋势。
本项目通过多源数据开展分析，未自主生成自有原始数据集。研究成果已发表于多篇学术出版物，其中部分内容仅可通过提供的链接供澳大利亚南极局（Australian Antarctic Division, AAD）工作人员下载。
所用数据源如下：
1. 澳大利亚气象局（Australian Bureau of Meteorology）提供的墨尔本与珀斯逐日最高气温及降雨量台站观测数据
2. 美国国家环境预报中心（National Centers for Environmental Prediction, NCEP，美国华盛顿）再分析数据集
3. 欧洲中期天气预报中心（European Centre for Medium-Range Weather Forecasts，英国雷丁）ERA-40再分析数据集
4. 美国国家冰雪数据中心（National Snow and Ice Data Center, NSIDC，美国博尔德）提供的海冰数据
