The CLIVAR Pacific Regional Panel held the 2nd Tropical Pacific Decadal Variability (TPDV) Workshop at Sorbonne University in Paris, France from 1 to 5 April 2019, with the strong support of LOCEAN/IPSL. Eighteen scientists participated in the workshop, including six CLIVAR Pacific Regional Panel members, four former CLIVAR ENSO Research Focus members, two members of the CLIVAR Decadal Climate Variability Predictability Research Focus and other invited experts on different aspects of TPDV, its predictability and its prediction. The participants also received suggestions and input from other colleagues who were unable to attend the meeting in person.  The majority  of the participants have been involved since the first TPDV workshop, in San Pedro de Manglaralto, Ecuador on 13-14 October 2018.

The goal of the workshop was to make progress on a review paper on TPDV. During the first day of the workshop, only the lead authors of each section of the paper met to outline a strategy for the following days. On April 2-5, plenary sessions that included scientific talks on issues directly relevant to the review alternated with breakout sessions targeted to advance individual sections of the paper.  The workshop achieved its goal by strongly advancing the synthesis of the current state-of-knowledge on TPDV and its implications for prediction. A manuscript for submission will be finalized in the next few months.
