SuperUser Account Monday, June 26, 2017 / Categories: Research Headlines, Climate, Weather , 2017 NOAA and international partners plan upgrade of global weather and ocean observing system NOAA met with ocean observations experts from six nations and 13 global organizations in May 2017 in Honolulu, Hawaii, to plan for the redesign of the Tropical Pacific Observing System by the year 2020 (TPOS 2020). TPOS is an ocean-based monitoring network comprised of a variety of observing technologies, operated by NOAA and other foreign partners. This network provides the essential ocean data needed to understand important environmental phenomenon and develop weather and climate forecasts for the US and countries around the world. Seasonal forecasts and prediction of El Niño and La Niña events, driven by El Niño Southern Oscillation (ENSO), depend upon the ocean and weather conditions monitored by TPOS. El Niño occurs when the sea surface waters of the tropical Pacific Ocean warm significantly above average and La Niña events occur when these waters cool to temperatures below average. These changes can drive shifts in United States weather patterns across the nation as well as global patterns of rain and resulting floods, drought and accompanying wildfires, and can lead to shifts of fisheries stocks, among many other effects. Accurate ENSO predictions can protect lives and property, boost economic prosperity, and provide vital information for global decision-makers, private industries, and others to plan for the future. Since the original tropical Pacific moored array was launched in the late 1980s, scientists have gained a better understanding of ENSO with continuing observations from TPOS, enabling forecasts of upcoming ENSO events that help countries to prepare for impacts. Now scientists are working to boost the reliability of TPOS to improve forecasts of the onset, duration, and intensity of ENSO events and their regional-to-local impacts. The enhancements to TPOS envisioned in the TPOS 2020 First Report, which was released in December 2016, will optimize buoy locations, encourage more voluntary ship and research cruise observations, and incorporate new, more affordable ocean observing technologies. The participating organizations endorsed the recommendations of the report and formed an implementation team charged with developing a concrete strategy to bring these upgrades to fruition. The TPOS 2020 initiative depends on strong international partnerships and continued US engagement. Success of this initiative will accelerate advances in the understanding and prediction of weather and climate in the tropical Pacific and their effects on multiple sectors in the US and around the globe, ranging from agriculture, marine ecosystems, human health to disaster preparedness. The participating organizations included: Bureau of Meteorology (Australia); Comision Permanente del Pacifico Sur; Commonwealth Scientific and Industrial Research Organization (Australia); France Institut de Recherche pour le Developpement; Indonesia Meteorological, Climatological and Geophysical Agency; Intergovernmental Oceanographic Commission; International Center for the Investigation of the El Nino Phenomenon; Japan Marine-Earth Science and Technology Center; National Aeronautics and Space Agency (United States); National Marine Env. Forecasting Center, State Oceanic Administration (China); National Oceanic and Atmospheric Administration (United States); Qingdao National Laboratory for Marine Science and Technology (China); Republic of Korea Institute of Ocean Science and Technology; Secretariat of the Pacific Regional Environment Programme.

Low-oxygen waters off Washington, Oregon coasts risk becoming large 'dead zones' 21Jul2021 Read more A large area of poorly oxygenated water is growing off the coast of Washington and Oregon. Scientists say oxygen levels may fall low enough to create "dead zones." Read more
Deforestation, warming flip part of Amazon forest from carbon sink to source 14Jul2021 Read more New results from a nine-year research project in the eastern Amazon rainforest finds that significant deforestation in eastern and southeastern Brazil turned what was once a forest that absorbed carbon dioxide into a source of planet-warming carbon dioxide emissions.

Human activities responsible for rapid increase in Earth's heat 28Jul2021 Read more A new study by Princeton University and NOAA researchers has found clear evidence of human influence on Earth’s climate in the past two decades of satellite measurements. “Human activity strongly influenced the positive trend in Earth's energy imbalance, causing a significant increase in the heat stored in the planet,” said Shiv Priyam Raghuraman, the lead researcher on the study.

2020’s Economic Slowdown Provides Opportunity to Investigate Ozone Pollution in the U.S. 16Sep2021 Read more When COVID-19 pandemic began in the US, counties and cities across the nation imposed stay at home orders, closed schools or imposed travel restrictions. From March 2020 onward, many Americans hung up car keys and settled into their homes for work and school. Traffic patterns dramatically changed, and previously smog filled vistas became clearer.
