A collaboration paper between SEFSC and AOML/PhOD scientists Potential impact of climate change on the intra-Americas sea: Part 2. Implications for Atlantic bluefin tuna and skipjack was selected as a NOAA research highlight.
From its onset to the decay, El Niño-Southern Oscillation (ENSO) plays an important role in forcing climate variability around the globe. A new study led by Sang-Ki Lee, a PhOD/CIMAS scientist, provides an efficient approach to explore the differences in the evolution of space-time patterns of sea surface temperature observed during El Niño events
In a recent article accepted for publication in the Journal of Climate, scientists in PhOD, S.-K. Lee (CIMAS) and C. Wang collaborated with R. Mechoso and D. Neelin, both at UCLA, to explore why the southern subtropical anticyclones are notably stronger in the austral winter than in summer, which is in contrast with the Northern Hemisphere (NH) in which subtropical anticyclones are more intense in summer according to the monsoon heating paradigm. They performed model experiments to show that during the boreal summer enhanced tropical convection activity in the NH plays important roles in strengthening the southern subtropical anticyclones.
The record-breaking U.S. tornado outbreaks in the spring of 2011 prompt the need to identify long-term climate signals that could potentially provide seasonal predictability for U.S. tornado outbreaks. A new research led by scientists in the Physical Oceanography Division of NOAA-AOML used both observations and model experiments to show that a positive phase Trans-Niño may be one such climate signal.
A new study led by researchers from University of Miami, NOAA-AOML, IFM-GEOMAR, and NCAR explores why the Atlantic Ocean has warmed substantially more than any other ocean basin since the 1950s. The research article published in the Geophysical Research letters evidences that the observed large warming of the Atlantic Ocean since the 1950s is largely induced by an increase in the inter-ocean heat transport from the Indian Ocean via the Agulhas leakage. The study points to an important role played by the Atlantic meridional overturning circulation (AMOC) in the South Atlantic in enhancing the secular warming of the Atlantic Ocean.
A joint workshop hosted by NOAA and the National Aeronautics and Space Administration (NASA) for bluefin tuna research was held at the University of Miami on December 6-7th. Researchers with AOML’s Physical Oceanography Division (PhOD) presented the results of their collaborative efforts with NOAA’s Southeast Fisheries Science Center (SEFSC), which have focused on the link between the ocean and stock assessment species of relevant commercial importance.
