Top Image: Latest global monthly sea surface temperature anomalies from the Extended Reconstructed SST Version 2 data set.
2nd Image: Three-month running average time series of standardized SST anomalies averaged over the global tropics (25°S to 25°N, Tropics_SSTA, red), the NINO 3.4 region (170°W to 120°W, 5°S to 5°N, NINO_3.4, black), and tropical ocean areas, excluding the eastern Pacific (80°W to 180°, 25°S to 25°N, Tropics-East Pac SSTA, green)
3rd Image: Three-month running average time series of standardized SST anomalies averaged over the global oceans equatorward of 55° latitude (55°S to 55°N, Globe_(55S-55N)_SSTA, red), the extratropical oceans in both hemispheres (55°S to 25°S, 25°N to 55°N, Extratropics_(25-55 NH,SH)_SSTA, blue), and the NINO 3.4 region (170°W to 120°W, 5°S to 5°N, NINO_3.4, black)
Bottom Image: Three-month running average time series of standardized SST anomalies averaged over the southern hemisphere extratropics (55°S to 25°S, SH_Extratropics_SSTA, blue) and the northern hemisphere extratropics (25°N to 55°N, NH_Extratropics_SSTA, red)
