Global Sea Surface Temperatures At A Standstill
There’s nothing too exciting for this update. Global sea surface temperatures are at about +0.27 deg C for the week centered on July 17th, compared to the base years of 1971-2000.
The sea surface temperature anomalies of the NINO3.4 region in the equatorial Pacific (5S-5N, 170W-120W) are a commonly used metric for the frequency, strength and duration of El Niño and La Niña events. For the week centered on Wednesday July 17, 2013, they were at about -0.29 deg C. That is, there aren’t El Niño or La Niña conditions, which have thresholds of +0.5 deg C and -0.5 deg C, respectively.
But sea surface temperatures in the eastern equatorial Pacific are still quite cool. The NINO1+2 region is bordered by the coordinates of 10S-0, 90W-80W, and its sea surface temperature anomalies are approximately -1.7 deg C.
