PMEL staff are aboard two international vessels to recover and deploy moorings in the Indian Ocean as part of the Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA) project.  RAMA was initiated in 2004 to collect key oceanographic and meteorological data from the poorly observed Indian Ocean. 

The establishment of one new site this month will mark the occupation of 30 sites, with a total of 46 sites planned for the entire array.  For more information, please visit the RAMA web site.

PMEL technicians departed the week of January 7 for a 7-week cruise on the NOAA Ship Ronald H.Brown in the Northeast Atlantic to service moorings in the Prediction and Research Moored Array in the Atlantic (PIRATA).  PMEL will be deploying 5 moorings at 4 PIRATA sites. 

The PIRATA array was established in 1997 in partnership with France and Brazil and studies ocean-atmosphere interactions in the tropical Atlantic.  Visit the PIRATA web page for more information.

In both present-day climate (a) and future climate (b), convection zones in the western Pacific and the ITCZ latitudes shift from their normal positions (blue clouds) to the equatorial Pacific during an extreme El Niño event (red clouds).

For the first time, in a research article published January 19 in Nature Climate Change, PMEL’s Dr. Michael McPhaden and a team of international scientists provide robust and convincing evidence that greenhouse warming will double the chance of extreme El Niño events in the coming decades. The scientists examined 20 climate models and found a doubling of extreme El Niño events, like the one in 1997-98, from present-day through the next 100 years in response to greenhouse warming.
