Southwest Pacific Enhanced Archive for Tropical Cyclones (SPEArTC)

Welcome to the Southwest Pacific Enhanced Archive for Tropical Cyclones (SPEArTC) Page

This page is devoted to research concerning Tropical Cyclones in the Southwest Pacific – for the purposes of this research, the area of study is south of equator to about 40° South and stretches from near French Polynesia around 120° West and then west to the Gulf of Carpentaria in Australia at 135° East longitude. This research has begun with the creation of a South Pacific Enhanced Archive of Tropical Cyclones (SPEArTC) which is freely available but for the purposes of tracking usage and being able to contact users when changes occur, I respectfully request that you please register for this dataset in the Resources section of this page.

The SPEArTC dataset has been CORRECTED as of January 12, 2024, as follows: (1) to incorporate 13 best tracks for the 2022/23 season; (2) courtesy of Steven Young at ASW, a set of 8 best tracks for the 1900-01 season has also been incorporated; (3) courtesy of Luis Muñoz Leyton of the University of Valparaiso, Chile, a number of corrections and additions in the southeast portion of the basin closer to the west coast of South America; and (4) courtesy of both Olivia Yu from MeteoFrance and Joe Courtney from the Australian BoM, some corrections from various seasons as noted in top portion of the CSV file.
