Monthly SST anomalies 1920–2016
August 30, 2017

New research confirms that links between warm and cool years in the California Current System and El Niño are important but imperfect.

Researchers have developed a state-of-the-art drought and wildfire prediction system, showing the multi-year predictive skills of drought and wildfire conditions beyond the typical timescale of seasonal climate forecast models. 

sea surface height anomalies and upper-ocean temperature from the NOAA Kuroshio Extension Observatory
April 26, 2017

Approximately seven years of daily-averaged autonomous CO2 observations from NOAA’s Kuroshio Extension Observatory surface mooring were used to close the mixed-layer carbon budget, finding high rates of net community production during the spring bloom period.

Warm Blob
March 3, 2017

New research shows the extent and development of 'the Blob' using satellite surface temperature data to reveal warm temperature anomalies appearing as early as March 2014 in the central and southern California coast, and eventually extending to the entire West Coast and dissipating in August 2016.

Time series of eastern Indian Ocean thermocline depth in an ocean model hindcast
March 1, 2017

In a new paper from Journal of Climate, researchers show that changes in the Indian Ocean subsurface heat content over the last 50 years can be linked to Pacific Ocean variability associated with the Pacific Decadal Oscillation/Interdecadal Pacific Oscillation.

Composite analysis of sea surface temperatures based on Atlantic Water temperature variability.
October 26, 2016

Research shows that decadal shifts of subsurface Atlantic Water temperatures, along the North Atlantic Current, are associated with a progression of heat anomalies from the Gulf Stream region that coincide with sea surface temperatures extending to cover most of the subpolar and tropical North Atlantic; a signal similar to that of the Atlantic Multidecadal Oscillation.

Indo-Pacific tropical rain belt expanded and contracted in the past
October 5, 2016

A new study using a high-resolution stalagmite record from Australia with cave sites in southern China reveal a close coupling of monsoon rainfall on both continents, with numerous synchronous pluvial and drought periods, suggesting that the tropical rain belt expanded and contracted numerous times at multidecadal to centennial scales.

El Nino events and tropical cyclones, models compared to observations
September 7, 2016

It is well known that ENSO strongly affects the interannual variability of tropical cyclones in the western North Pacific. New research shows that models can reproduce interannual variability, but none can capture the distinction between eastern Pacific and central Pacific El Niño events that is found in observations.

Sea level rise in the Pacific
September 1, 2016

The Pacific Ocean has a significant influence on global mean surface temperature, as recently demonstrated during the 2015/16 El Niño. New research shows a new way to quantify the role of the Pacific Ocean using sea level information rather than traditional sea surface temperature data.

wind and temperature anomalies
May 18, 2016

New research shows how easterly winds in the summer of 2014 caused the anomalously warm subsurface water of the tropical Pacific—which presages an El Niño event and formed following the early 2014 westerly wind burst—to never discharge poleward, thereby remaining in the tropical Pacific and giving a head start to the developing 2015-16 El Niño.
