(24th Prediction and Research Moored Array in the Tropical Atlantic /Tropical Atlantic Variability Meeting)
Virtual Meeting
10 May, 2021 to 14 May, 2021


The Prediction and Research Moored Array in the Tropical Atlantic/Tropical Atlantic Variability (PIRATA/TAV) meeting is held approximately once per year and welcomes participants from around the world. The last meeting took place October 22-24, 2018 in Marseille, France, PIRATA 23 and 2nd TAOS Review Workshop. Climate variability in the tropical Atlantic affect rainfall in South America and Africa, sometimes leading to extreme droughts or floods. The tropical Atlantic also experiences extreme events such as hurricanes and marine heatwaves. Variability outside of the tropical Atlantic has a strong impact on TAV, and atmospheric teleconnections from the tropical Atlantic affect tropical Pacific and Indian Ocean variability. There is growing evidence that long-term changes in the tropical Atlantic Ocean are altering hurricane activity, ocean biogeochemical cycles, and ecosystems.

To address these challenges, PIRATA was started in 1997 and now consists of 18 open-ocean moorings that measure upper-ocean and surface atmospheric conditions and transmit their data in real-time for use in operational weather forecasting and ocean state estimation. The array is maintained through a partnership between the U.S. (NOAA), France (Meteo France and IRD), and Brazil (INPE and DHN) and forms the backbone of the Tropical Atlantic Observing System (TAOS). The main purposes of PIRATA are to improve understanding of the tropical Atlantic Ocean, climate, and air-sea interactions; to aid in weather and climate prediction; and to monitor long-term changes in the ocean and atmosphere.

Meeting Objectives

PIRATA and the broader TAOS have evolved considerably over the past two decades in response to changing research and operational needs. This progress would not have been possible without strong international commitment to PIRATA and the collaborative nature of the PIRATA and TAV communities. The main goal of the meeting is to advance tropical Atlantic science by bringing together a diverse group of tropical Atlantic researchers and stakeholders. Recently, assessments of TAOS were made through a CLIVAR review, Tropical Atlantic Observing System Review and several tropical Atlantic focused OceanObs’19 white papers. These review efforts put forward a series of recommendations for tropical Atlantic observations and science. We plan to discuss how the PIRATA/TAV community can implement some of those recommendations.

Meeting Science Themes

  1. Earth system mechanisms (atmosphere, ocean, land, ice) affecting tropical Atlantic climate
  2. Simulation and predictability of tropical Atlantic climate variability and change
  3. Physical-biogeochemical-ecosystem interactions and impacts on ocean and human health
  4. Impacts of the Tropical Atlantic Observing System on models, forecasts, and reanalyses
  5. Extreme weather and climate events

Meeting Format

At the The Mayfair at Coconut Grove: The main meeting will take place over three days, April 20-22. There will be a half-day PIRATA Science Steering Group (SSG) and Resource Board (PRB) meeting during the morning of the first day. Then, there will be two and a half days of science meetings open to all participants, consisting of oral, poster, and discussion sessions. Participants may attend the meeting without submitting an abstract, but must register.
