The DYNAMO (Dynamics of the Madden-Julian Oscillation) field campaign was designed to collect observations in the Indian Ocean needed to improve the representation of processes key to understanding and modeling the Madden-Julian Oscillation (MJO). Following the field phase, a recent competition invited the academic community to assemble diverse Climate Process Teams consisting of observationalists, theoreticians, and modelers. These teams were tasked with integrating the new observations and expanded understanding gained during the field phase into NOAA’s operational weather forecasting and global climate models in order to improve initiation and propagation of the MJO in these models.
NOAA’s Climate Variability and Predictability (CVP) program competitively funded 2 new three-year projects totaling $2.4 million in grants and $598,000 in other awards to support 20 researchers, postdocs, and students at 10 institutions. Altogether, these projects represent a collaboration between academia and NOAA to improve the Geophysical Fluid Dynamics Laboratory’s state-of-the-art global climate model as well as the operation model CFS (Coupled Forecast System), which is used at the National Centers for Environmental Prediction within NOAA’s National Weather Service. The research conducted by these teams will help reduce model biases and improve environmental forecasts along the weather-climate continuum.
Skillful weather forecasts extend out 1-2 weeks while climate projections encompass seasons, decades, and centuries. Current models do not adequately address the important sub-seasonal forecasting gap in between these timescales, but predictions at this scale are important for planning in a variety of fields, such as farming, water resource management, and futures trading. Improving our ability to forecast environmental conditions in the sub-seasonal time frame requires an improved understanding of components or phenomena of the Earth system that operate on that scale.
The most prominent example of such a phenomenon at this scale is the Madden-Julian Oscillation (MJO),which cycles on roughly 30-90 day intervals. Starting in the Indian Ocean and propagating slowly eastward into the Pacific, the MJO is a convective system, characterized by clouds and rainfall, that influences weather and other phenomena such as the El Niño-Southern Oscillation (ENSO). Improving understanding of how this source of climate variability is initiated and how it moves around the globe can improve forecasts on the subseasonal timescale. The Climate Process Teams will not only use NOAA-supported field campaign data to better understand the MJO, but also will incorporate this knowledge into our models to operationalize this understanding.Projects

CVP is a program in the Climate Program Office, within NOAA’s Office of Oceanic and Atmospheric Research, that supports research to advance understanding of the climate system through observation, modeling, analysis, and field studies.

NOAA’s Climate Program Office helps improve understanding of climate variability and change in order to enhance society’s ability to plan and respond. NOAA provides science, data, and information that Americans want and need to understand how climate conditions are changing. Without NOAA’s long-term climate observing, monitoring, research, and modeling capabilities we couldn’t quantify where and how climate conditions have changed, nor could we predict where and how they’re likely to change.
