For a decade and a half, US CLIVAR has promoted the concept of Climate Process Teams (CPTs). CPTs are a useful way to transfer process-oriented research into climate model development. The history of CPTs, key lessons from past efforts, and how to propose future projects are outlined on the website.

The most recent edition of Variations is themed "Expansion of the tropics" and focuses on the magnitude, cause, and impacts of the recent expansion of the tropical belt region. The articles present some of the most pressing research questions, ideas for standardizing methods, the role of anthropogenic and natural variability, and how widening varies by region with different impacts over land and the ocean.

In its 10th year, the US AMOC Science Team report captures progress on the main objectives of the program, identifies new programmatic gaps,  provides near- and long-term research priorities, and outlines activities leading up to the sunset of the team. 

Over 50 participants gathered in Boulder, Colorado, on May 1–3 to discuss pathways for bridging observations to data assimilation for understanding the tropical Pacific, as part of the TPOS 2020 project. The presentations and posters presented during the workshop are available online for viewing. A workshop summary and report will be forthcoming. 

The upcoming workshop on Bridging Sustained Observations and Data Assimilation for TPOS 2020 will be webcast on Tuesday, May 1. The opening day of the workshop will feature plenary presentations from the observational, modeling, and data assimilation communities. 

The US CLIVAR Working Group on Observations and Modeling of Water Isotopes in the Climate System was formed in April 2018 and will wrap up in three years. The intent of the working group is to is to characterize and utilize water isotope ratios as a climate variable. 

We are looking to hire a Meeting and Event Planner III to provide the US CLIVAR program with meeting, financial, and operations management to advance the multi-agency funded program goals. This position will be located in Washington, DC. Applications are due April 25. 

The PSMI Panel is organizing a webinar series on proposed and current process studies starting in April 2018. The goals of this series are to provide feedback on the process study/field campaign plans and distill programmatic lessons learned. The webinars are open to the entire community. 

Members of a US CLIVAR Working Group and a recent workshop have published a white paper on Arctic change and possible influence on mid-latitude climate and weather. This report brings together experts in the fields of atmospheric, oceanic, and cryospheric sciences to assess the rapidly evolving state of understanding, identify consensus on knowledge and gaps in research, and develop specific actions to accelerate progress within the research community.

The US CLIVAR/OCB Southern Ocean Working Group published a paper on observationally based metrics that help standardize the evaluation of climate models and reduce the uncertainty in projections in the Southern Ocean.
