SGER: Creation of a Homogeneous Self-Consistent Tropical Cyclone Intensity Database for the Immediate Purpose of Performing Global Intensity Trend Analyses

热带气旋指数将利用一个新的数据库来研究热带气旋的强度和趋势。该数据库包括1983年至今的全球红外图像，最近在美国国家海洋和大气局国家气候数据中心(NCDC)建立。PI将对数据库应用客观算法，以形成20多年来连续3小时全球热带气旋强度估计的同质自洽集合。这些估计随后将受到趋势分析的影响。拟议工作的动机是，目前的热带气旋强度测量和估计档案存在重大不一致之处。这些档案包括所谓的“最佳跟踪”数据。这项研究将直接解决在过去23年中，热带气旋强度是否表现出任何显著的年际趋势。PI将创建的同类数据库将使他能够考虑趋势，而不会因当前最佳轨道数据的不均一性而受到无数警告。更广泛的影响：在变暖的环境中，总的热带气旋强度是否正在增加的问题与我们全球社会的利益和关切非常相关，并对世界各地沿海社区内死亡和破坏的潜在趋势具有广泛的影响。

The PI will take advantage of a new database to study tropical cyclone (TC) intensity and trends. The database, which comprises global infrared (IR) imagery for the period 1983 to present, has recently been constructed at the NOAA National Climate Data Center (NCDC). The PI will apply an objective algorithm to the database to form a homogeneous self-consistent collection of over 20 years of uninterrupted 3-hourly global TC intensity estimates. These estimates will then be subjected to trend analyses. The proposed work is motivated by the presence of significant inconsistencies in the present archives of TC intensity measurements and estimates. These archives comprise what is known as "best track" data. This research will directly address whether TC intensity has exhibited any significant interannual trends during the past 23 years. The homogeneous database that the PI will create will allow him to consider trends without the numerous caveats related to the inhomogeneity of the present best track data. Broader Impacts: The question of whether overall TC intensity is increasing in a warming environment is very relevant to the interests and concerns of our global society and has broad implications in regard to potential trends in death and destruction within coastal communities worldwide.
