US AMOC - UK RAPID: Monthy AMOC Webinar

From 21 May 2020

US AMOC and UK RAPID have organized a webinar series to share summaries of the papers published in the AGU Special Issue. The webinars will be held on the third Thursday of the month at 4pm BST / 11am EDT, starting on 21 May 2020. Each webinar will be scheduled for 30 minutes, with 20 minutes for presentation and 10 minutes for questions.

For the full schedule, see US CLIVAR's AMOC Webinar page

Next: 19 November 2020 4pm BST / 11am EDT

US AMOC - UK RAPID International Meeting 2018

14 - 17 July 2018, Miami, Florida

The meeting drew 103 scientists whose presentations explored the oceanic regions (tropical, subtropical, and subpolar) over which common forcing mechanisms control AMOC variability. For more information see the meeting report in EOS (published 30 Jan 2019).

Joint ACSIS - OSNAP - RAPID Science Meeting

19 - 21 September 2017, Oxford, UK

This meeting brought together scientists from three UK programmes, ACSIS, OSNAP, RAPID, and the wider UK science community to explore change and variability in the North Atlantic climate system (atmosphere, ocean, cryosphere), on time scales from days to decades. The meeting had four themes:

  1. Ocean-atmosphere-cryosphere interactions
  2. Characterising the North Atlantic climate system in 4-D
  3. Understanding change and variability
  4. Towards budgets

The RAPID Challenge

Preliminary AMOC time series plotted with the 10 competition entries

RAPID Challenge: predictions and data
Thick black line: provisional RAPID data (vertical bars are +/- 1 Sv). Thick dashed line: mean of all the predictions. Coloured lines show the individual predictions; of these the two best estimates are highlighted with thick lines.

In autumn 2015 the RAPID team collected the most recent data from their array of moorings across the Atlantic at 26°N. Before this they issued a challenge to the climate and ocean science community: can you predict what the new data will show? Ten science teams tried their hands at prediction. The winning teams and their methods can be found on the RAPID Challenge web page. Some of the teams also contributed to the RAPID Challenge blog, which followed the RRS Discovery as she collected the measurements from the RAPID array.

RAPID - US AMOC International Science Meeting

21 - 24 July 2015, Bristol, UK

This meeting continued the UK-US collaborative workshop series focussing on the Atlantic meridional overturning circulation (AMOC) and its impacts on weather, climate and ecosystems, in the past, present and future. A holistic understanding of the AMOC can only be achieved by comprehensive observations (both present day and paleo), by the use of climate and earth system models, and by synthesizing observations and models. Therefore, the meeting addressed the following themes:

  1. Characterising the AMOC - structure, variability, mechanisms and ocean response
  2. Impacts of the AMOC on the atmosphere, cryosphere, and land
  3. AMOC state estimation, predictability and prediction
  4. Novel approaches to pan-Atlantic observations, modelling, analysis and synthesis

RAPID-AMOC meeting, 18-19 September, 2014

10 years of observations of the Atlantic Meridional Overturning Circulation: results from RAPID, surprises and future plans

The joint UK-US RAPID programme has been making observation of the Atlantic Meridional Overturning Circulation (AMOC) since April 2004. In 2014 RAPID attained the major milestone of 10 years of continuous observations of the AMOC. To mark this milestone, a day-and-a-half meeting was held in London, at Church House, on 18-19 September 2014.

The aims of the meetings were:

Invited speakers included Professor Ian Boyd (chief scientific adviser, Defra), Professor Susan Lozier (Duke University) and Professor Charles Eriksen (University of Washington). Download Detailed Programme (PDF)
