人们普遍认为，热带西南太平洋区域的小岛屿国家和领土的生态系统和经济是世界上最容易受到气候多变性和极端天气影响的国家之一。热带气旋（TC）能够加剧现有的灾害和那些因气候变化而变得更加严重的灾害（例如当地海平面上升）。为了正确了解热带气旋对该区域的影响，需要建立一个热带气旋轨迹综合数据库。这项工作整理了来自地球仪预报中心的TC最佳轨迹数据，目的是为历史时期制作统一的全球最佳TC轨迹数据集。来自西南太平洋（东经135度120度，南纬5度25度）的国际气候管理最佳跟踪（IBTrACS）项目信息的数据是建立在这一努力的基础上的，并包括在这一努力中。我们的文件建设的增强型TC数据库的西南太平洋，建设数据库所需的质量控制，并讨论它如何增强了年表的区域范围内的历史TC活动，根据新发现的数据。我们建议这个增强的数据集可以用于即将到来的气候和天气研究，以更好地描述西南太平洋TC的气候和行为。版权所有（c）2011皇家气象学会
The ecosystems and economies of small island nation states and territories of the tropical southwest Pacific region are widely agreed to be among the most vulnerable to climate variability and weather extremes anywhere in the world. Tropical Cyclones (TCs) are capable of exacerbating existing hazards and those made more severe by climate change (e.g. local sea level rise). In order to properly understand TC impacts in this region, a comprehensive database of TC tracks is required. This work has collated TC best track data from forecast centres around the globe with the aim of producing a unified global best TC track dataset for the historical period. Data from the International Best Tracks for Climate Stewardship (IBTrACS) project information for the southwest Pacific (135 degrees E120 degrees W, 5 degrees 25 degrees S) is built upon and included in this effort. We document the construction of an enhanced TC database for the southwest Pacific, the quality controls needed to construct the database, and discuss how it has enhanced the chronology of region-wide historical TC activity in light of newly discovered data. We suggest this enhanced dataset can be used in forthcoming climate and weather studies to better characterize the climatology and behaviour of TCs in the southwest Pacific.
