Projected response of the Indian Winter Monsoon Winds over the Arabian Sea to Climate Change

A recent study indicates a robust reduction of the Indian Winter Monsoon wind intensity over the Arabian Sea by the end of the 21st century in all the 27 analysed CMIP5 models (a reduction of 6.5% for Representative Concentration Pathways (RCP) 8.5 and 3.5% for RCP4.5, on an average), which is not yet detectable in observations. 

What is responsible for recent decadal changes in the subpolar North Atlantic Ocean’s heat content?

This article will show the mechanisms underlying recent decadal changes in subpolar North Atlantic Ocean (SPNA) heat content, with results implying that predictability of SPNA decadal changes is intimately tied to the predictability of the overlying atmosphere.

Recent slowing of Atlantic overturning circulation as a recovery from earlier strengthening

A new ocean ‘reanalysis’ shows, although there are uncertainties over what might happen in the short term, the longer-term view is that a weakening of the circulation in the 21st century is still very likely as a result of increasing greenhouse gases.

ENSO and greenhouse warming

ENSO's response to greenhouse warming has challenged scientists for decades, despite model agreement on projected mean state changes. Recent studies have provided new insights into the elusive links between ENSO and Pacific climate mean-state changes.

Pacific western boundary currents and their roles in climate

The influence on ENSO's life cycle via equatorward WBC transport, the longevity of SST anomalies and strong advection transport of warm water by the Kuroshio Current, the considerable impact on Asian Monsoon via anomalous heat content exerted by the North Pacific WBCs, all have substantial climate impacts locally and globally.
