NINO3.4

GLOBAL

Weekly Global SST anomalies have been relatively stagnant in recent weeks. Global SST anomalies usually lag NINO3.4 SST anomalies by a few months so it’s likely the slow rebound from the La Niña minimum will continue. For the week centered on July 13, 2011, Global SST anomalies are +0.15 deg C.

This weekly Reynolds OI.v2 SST dataset begins in 1990. I’ve started the graphs in 2004 to make the variations visible.
