Modeling western North Pacific tropical cyclones associated with ENSO
Modeling western North Pacific tropical cyclones associated with ENSO

It is well known that ENSO strongly affects the interannual variability of tropical cyclones in the western North Pacific. New research shows that models can reproduce interannual variability, but none can capture the distinction between eastern Pacific and central Pacific El Niño events that is found in observations.

Pacific sea level rise and temperature
Pacific sea level tilt predicts global temperature changes

The Pacific Ocean has a significant influence on global mean surface temperature, as recently demonstrated during the 2015/16 El Niño. New research shows a new way to quantify the role of the Pacific Ocean using sea level information rather than traditional sea surface temperature data.

Prediction uncertainty associated with model simulations of an ice-free Arctic due to internal variability and differences in emissions.
How predictable is the timing of a summer ice-free Arctic?

New research focused on determining how well the occurrence of an ice-free Arctic can be predicted. What the researchers found is that the uncertainty for the prediction of an ice-free Arctic, caused by internal climate variability, amounts to around two decades.

Rainfall over Florida is impacted by ocean currents
Future changes in ocean currents around Florida impact rainfall over land

Robust surface ocean currents around Peninsular Florida, namely the Loop and the Florida Currents, are shown to affect the terrestrial wet season of Peninsular Florida. New research shows that differences in the ocean bathymetry (or topography) of two novel numerical climate model integrations can influence the ocean currents and their impact on regional climate.

Antarctic sea ice helps maintain the Southern Ocean overturning circulation

Recent trends in sea ice have been studied heavily. A less well-understood problem is how sea ice affects the underlying ocean, particularly the poorly observed Southern Ocean. A new study shows how the seasonal drift of Antarctic sea ice may be more important for the global ocean overturning circulation than previously realized.

Modes shows lag correlations with temperature
A cautionary note on the use of surface heat fluxes to diagnose the causes of the Atlantic Multidecadal Oscillation

The Atlantic Multidecadal Oscillation is a naturally occurring pattern of sea surface temperature change that is seen in the North Atlantic on decadal timescales and affects weather and climate. Some have suggested that the AMO is a consequence of variable large-scale ocean circulation. Yet new research suggests otherwise.

Welcome to the US Climate Variability and Predictability Program

Daily highlights from the CLIVAR Open Science Conference

Detlef Stammer of International CLIVAR

During the CLIVAR Open Science Conference, from September 19-23, daily highlights will be released on the website. These highlights will feature key ideas, discussions, and activities that will be taking place during the meeting. Live updates will also happen on twitter at #CLIVAR2016. 

2016 US AMOC Science Team report

AMOC report cover

The US AMOC Science Team releases its eighth progress report, since the inception of the program in 2008. The purpose of this report is to summarize progress on the main objectives of the program, identify any new programmatic gaps, and provide updates on both near-term and long-term research priorities, action items, and objectives for the program since the 2014 report.

Save the Date: 2017 Sea Level Rise Conference

Sea level rise will impact coastal communities

The WCRP, jointly with the Intergovernmental Oceanographic Commission of UNESCO, is organizing an international conference on sea level research that will address the existing challenges in describing and predicting regional sea level changes and in quantifying the intrinsic uncertainties. The "Regional Sea Level Changes and Coastal Impacts" conference will be held July 10-14, 2017 at The Earth Institute/Columbia University in New York. 

Fall 2016 call for new US CLIVAR workshops and working groups

ENSO and ecosystems workshop participants

Requests are now being accepted for US CLIVAR-sponsored workshops and one new working group for 2017. Submissions are encouraged from the US climate science community. All documents must be submitted by October 7, 2016. The next call for workshops will be in spring 2017. 

White paper on translating process understanding for climate models

Global SST from NOAA model

A new white paper has been released based on a 2015 US CLIVAR workshop, "Translating Process Understanding to Improve Climate Models." The document summarizes responses from a community questionnaire, workshop presentations and discussions, and recommendations to help inform the broad research community and agency considerations.

Executive Director sought for CLIVAR International Project Office

CLIVAR international logo

The First Institute of Oceanography (FIO) and the World Climate Research Programme (WCRP) invite applications for the post of Executive Director of the International CLIVAR Project Office, based in Qingdao, China. The Executive Director will be responsible for a range of activities including fulfilling CLIVAR priorities as part of WCRP’s objectives and goals, managing the project office, participating in relevant meetings and workshops, promoting CLIVAR objectives, and seeking sources of additional funding. The position is available starting October 1. 

Intra-Americas Seas workshop report

This report highlights the virtual workshop that was held over three half-day sessions (September 9-11, 2015) and featured 47 oral and poster presentations that spanned observational and modeling studies and timescales from the paleoclimate to secular change, and also covered a wide range of phenomenological studies (e.g., tropical cyclones, mid-summer droughts, low level jets) for the Intra-Americas Seas.
