NOAA’s Climate Variability and Predictability (CVP) Program is funding eight new projects (10 academic awards, four NOAA Lab, Center or CI awards) for a two-year total of $3.961 million in FY18 intended to contribute to the goals of TPOS 2020.
CVP supports research that enhances our process-level understanding of the climate system through observation, modeling, analysis, and field studies. The CVP Program is a critical component of the integrated research enterprise at the NOAA Climate Program Office (CPO), and maintains important connections to the other CPO program areas. In order to improve understanding of the climate system and its representation in models we need high-quality, consistent, long-term observations of the many parameters of the climate system. The Ocean Observing and Monitoring Division (OOMD) of CPO provides high-quality long-term global observations, climate information, and products that are used by CVP-supported scientists to build improved theories for the complex dynamics of the many components of the climate system, and in turn OOMD is informed by the needs of the process modeling and climate variability community.
Eight new modeling studies have recently been funded by the Climate Variability and Predictability Program (CVP). The fundamental overarching goal of the Tropical Pacific Observing System 2020 (TPOS) effort is to enhance and redesign international observations of the tropical Pacific. In the First Report of TPOS 2020 (Tropical Pacific Observing System 2020, tpos2020.org), many recommendations and proposed actions were identified. These projects are pre-field modeling studies in support of the two proposed TPOS process studies, Pacific Upwelling and Mixing Physics (PUMP) and Air‐sea interaction at the eastern edge of the Warm Pool.
Motivation behind the Pacific Upwelling and Mixing Physics (PUMP) study is that equatorial upwelling is a poorly observed aspect of the climate system, however, that upwelling is a principal initiating tool for the strong ocean-atmosphere coupling of the equatorial Pacific. Wit the most consequential equatorial upwelling occurring in the Eastern and Central Pacific Ocean, cold water with high concentrations of nutrients and carbon dioxide are brought to within 100m of the surface. This equatorial upwelling process remains poorly understood and poorly constrained in climate models.
The western Pacific is identified by a warm and fresh pool - this is the result of the warm water accumulation by heavy rainfall and the equatorial trade winds in the central Pacific. Inspiration for this project is to understand the air-sea interaction processes and the role of upper ocean salinity in maintaining the warm sea surface temperatures at the eastern edge of the west Pacific warm pool. Air-sea interaction at the eastern edge of the warm pool studies will involve using a mix of fixed platforms and mobile observing systems that would follow the evolving warm pool ledge.
The eight new projects supported by CVP in FY18 include:
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.
