Dr. Chidong Zhang gave a talk at the NOAA Booth during AMS about his research on the Madden Julian Oscillation.

February 01, 2017

Last week, PMEL scientists attended the American Meteorological Society (AMS)’s Annual Meeting in Seattle, WA and the Alaska Marine Science Symposium (AMSS) in Anchorage, AK. Presentations covered research in the Bering Sea, data management and access, El Nino, sea ice, the Earth's energy imbalance, innovative technologies, and recent warming in the Pacific and others.

At AMSS, the Ecosystems and Fisheries-Oceanography Coordinated Investigations (EcoFOCI) group had multiple presentations and posters on the Bering Sea including topics on the recent marine heat wave in Alaska, linking annual oceanographic processes to contiguous ecological domains in the pacific Arctic, fish distributions, ecology, Saildrone and oceanography.

A wider range of topics were covered at AMS and included invited talks from Nick Bond, Chidong Zhang and Kevin Wood. Dr. Zhang spoke about the Dynamics of the Madden-Julian Oscillation; Kevin Wood presented the Old Weather Project using historical U.S. ship logbooks to collect and analyze historical climate data; and Nick Bond discussed the recent warming in the NE Pacific. The annual meeting is the world’s largest yearly gathering for the weather, water, and climate community and brings together atmospheric scientists, professionals, students, educators and research’s from around the world. AMS is the nation’s premier scientific and professional organization promoting and disseminating information about the atmospheric, oceanic, hydrologic sciences.

PMEL scientists, including scientists from the University of Washington's Joint Institute for the Study of the Ocean and Atmosphere (JISAO) and Oregon State University's Cooperative Institute for Marine Resources Studies (CIMRS) are attending the American Geophysical Union (AGU)’s Annual Meeting in San Francisco this week, December 12-16. AGU's Falling Meeting is the largest Earth and space science meeting in the world bringing together the Earth and space science community for discussions of emerging trends and the latest research. Poster and talk topics include data integration, El Nino Southern Oscillation (ENSO), Indian Ocean temperature trends, hydrothermal plumes and vents, carbon dioxide in the tropics and Gulf of Alaska, aerosol research, and heat impacts on marine ecosystems and fisheries, tsunamis, and acoustic research.

The 2016 Arctic Report Card will be released Tuesday morning in conjunction with a press conference led by NOAA’s Jeremy Mathis.  The 2016 Arctic Report Card brings together the work of 61 scientists from 11 nations to provide the latest information on multiple measures of Arctic environmental change, including air and sea surface temperature, sea ice, snow cover, vegetation, wildlife, and plankton abundance. Read the full report and highlights here as well as the press release. Watch the recorded press conference here

Researchers will also present during a press conference Thursday morning some of the first scientific results from the 2015 Axial Seamount eruption including discoveries of previously unknown structures and new glimpses into the volcano’s internal plumbing. These new insights into the world’s most active and well-studied underwater volcano may help scientists better understand all volcanoes and the hazards they pose. Read the press release here. Watched the recorded press conference here. 

Dr. Bob Embley from the Earth-Ocean Interactions group will be honored during the Awards Ceremony as part of the 2016 class of Fellows for his pioneering contributions to the understanding of deep-sea volcanism by fostering interdisciplinary investigations with advanced technologies.

This image shows water temperature (in degrees Celsius) at varying ocean depths and wind stress anomalies, averaged over the equatorial Pacific (120E-80W, 2S-2N) from January 2014 - 2016. Red colors represent higher than normal temperatures and longer arrows represent stronger than normal winds.

PMEL climate scientists describe in a recently published paper  the relationship between the 2014-15 failed El Niño and this year’s monster El Niño as well as any similarities between the past strong El Niño’s. They examined changes in sea surface and sub-surface temperatures, winds, and volumes of warm water in the Pacific Ocean from 2014 to 2016.

What they found was that the highly anticipated 2014-15 El Niño event failed due to unusually strong easterly winds in the summer of 2014 which prevented the warm surface water from shifting eastward as seen in a typical El Niño events and left a reservoir of warm water below the ocean’s surface.  This reservoir of warm water combined with strong westerly winds that appeared and continued throughout the spring and summer of 2015 led to the monster El Niño. They found a similar series of events that led to the 1991-92 El Nino event.

RAMA buoy

A new RAMA site was recently established near 4S 57E.  Charter vessel TETHYS SUPPORTER deployed the mooring to bring the completion of the RAMA array to 76%.

Research and commentary articles just published online in Nature Climate Change by NOAA/PMEL Senior Scientist Michael McPhaden and collaborators highlights the need for continued study into El Niño causes and effects. 

McPhaden’s commentary explores possible reasons why the much anticipated El Niño of 2014 failed to materialize, while an unforeseen strong El Niño is developing now. In the same issue, a review paper by McPhaden and colleagues explores the connection between global warming and El Niño/La Niña events.  Model results indicate that extreme El Niño and La Niña events will increase in number and intensity as the climate continues to warm.

PMEL scientists and local residents celebrate renewed collaboration.  

May 28, 2015

PMEL Tropical Moored Buoy Array technicians Patrick Berk and Bill Higley recently completed a collaborative RAMA cruise aboard Indonesian Research Vessel Baruna Jaya 1. While in Indonesia, they participated in formal ceremonies celebrating the pending bilateral agreement between PMEL and Indonesia's meteorology and climatology agency, BMKG. This cruise marked a new phase of U.S. – Indonesian cooperation to better understand ocean-climate variability and how it affects the planet, and builds on years of cooperation between the two countries.

The RAMA array of surface and subsurface moorings in the Indian Ocean complements NOAA’s tropical moored arrays in the Atlantic Ocean, the Prediction and Research Moored Array in the Tropical Atlantic (PIRATA), and in Pacific Ocean, the Tropical Atmosphere Ocean (TAO) array, and Japans Triangle Trans-Ocean Buoy Network (TRITON).  RAMA will improve description, understanding, and prediction of Asian monsoons, which affect one third of the world’s population.

An El Niño in the equatorial Pacific is expected to play a dominant role in the winter weather for the U.S. Temperatures are expected to be warmer than average across most of the western and central U.S. with cooler than average temperatures in the Southeast and mid-Atlantic states.

In an article recently published in Geophysical Research Letters, Tong Lee of the Jet Propulsion Lab in Pasedena and Mike McPhaden of PMEL analyzed 30 years of NOAA satellite sea surface temperature data and found that the intensity of El Niño events in the central equatorial Pacific has almost doubled in the past three decades, with the strongest warming in 2009-10. 

These “central Pacific” (CP) El Niño’s exhibit maximum warming in the central equatorial Pacific in contrast to the classical El Niños, which have maximum warming in the eastern equatorial Pacific.
