Mission

The Model Diagnostics Task Force is constituted to develop, coordinate, and implement process-based model evaluation metrics and a metrics framework in National modeling center metrics packages, leveraging ongoing efforts at the modeling centers toward advancing model evaluation and development capabilities.

This Task Force is constituted of researchers whose projects were successfully evaluated as part of the FY15 competition held by NOAA’s Modeling, Analysis, Predictions, and Projections program on the topic of Process Oriented Metrics. This competition was motivated by a number of factors, including community interest in moving beyond performanceoriented metrics toward processoriented metrics, ongoing efforts to develop next-generation climate and Earth system models, evolving plans for CMIP, and a need to link model development and evaluation efforts across modeling centers. Nine projects were selected as a result of the competitive process, including eight focused on developing metrics and one that will develop metrics as well as define a direction and framework for the overall effort.

Task Force Function and Implementation

This Task Force will initiate its activities in October 2015 and will have a duration of three years. It is expected that researchers who were selected through the NOAA competitive process will participate actively in this Task Force helping to build an integrative processoriented metrics framework serving NOAA and other modeling centers. Task Force membership may also include affiliates, elected by Task Force leadership, who are not supported by MAPP funding but whose expertise and work are relevant to achieving the goals of this task force. The Task Force will coordinate with other relevant ongoing diagnostic efforts including emerging community processoriented metrics efforts such as the WCRP/WGCM Metrics Panel, PCMDI’s UVCDAT effort, and the EMBRACE ESMValTool project.

The Task Force will connect all of the funded investigators and other invitees. Beyond enhancing communication between investigators, expectations of this group include contribution by the individual projects to the development and implementation of the collective effort with a focus on implementing a cohesive metrics framework, open documentation of the efforts, and a focus on maximizing the community utility of metrics and the metrics framework. It is expected the main group will have monthly teleconferences and consider inperson meetings, as appropriate.

 

As of Spring 2017, the Task Force has developed a functional Application Program Interface (API) for the metrics package, which is documented here. The linked document also describes the overall status of the effort as of April 2017. The API is python based and designed to be flexible such that metrics coded in different non-proprietary software packages can be integrated into the API.

Scientists say weak and wobbly polar vortex to blame for cold extremes

"Polar vortex" was the buzzword of 2014, as millions of people in the northeastern U.S., Europe, and Asia experienced first-hand its connection to record-cold winter temperatures. This high-altitude, low-pressure system that hovers over the Arctic in the winter goes through strong and weak phases, acting like a spinning top that eventually wobbles as it slows down. When the system is strong, the cold air is tightly contained on top of the North Pole; when it's weak, fragments of Arctic air can more easily escape into the mid-latitudes.

New research, funded by CPO's Modeling, Analysis, Predictions, and Projections (MAPP) program, shows that the polar vortex has shifted towards more frequent weak states and fewer strong states over the past few decades, with subsequent cold extremes seen during Eurasian winters. While these results can explain the variability (about 60%) of winter temperatures since 1990, the authors note that improvements in seasonal forecasts of winter conditions will likely depend in part on improved understanding of the influence of stratosphere (high-altitude) variability.

About MAPP

The Modeling, Analysis, Predictions, and Projections (MAPP) Program is a competitive research program in NOAA Research's Climate Program Office. MAPP's mission is to enhance the Nation's and NOAA's capability to understand, predict, and project variability and long-term changes in Earth's climate system. To achieve its mission, MAPP supports foundational research, transition of research to applications, and engagement across other parts of NOAA, among partner agencies, and with the external research community. MAPP plays a crucial role in enabling national preparedness for extreme events like drought and longer-term climate changes. For more information, please visit www.cpo.noaa.gov/MAPP.

ABOUT OUR ORGANIZATION

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2011, the United States experienced a record high number (14) of climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 670 lives, caused more than 6,000 injuries, and cost $55 billion in damages. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
