NOTE: This is the fourth monthly update with our new Version 6.0 dataset. Differences versus the old Version 5.6 dataset are discussed here.
The Version 6.0 global average lower tropospheric temperature (LT) anomaly for July, 2015 is +0.18 deg. C, down considerably from the June, 2015 value of +0.33 deg. C (click for full size version):
The global, hemispheric, and tropical LT anomalies from the 30-year (1981-2010) average for the last 7 months are:
YR MO GLOBE NH SH TROPICS
2015 1 +0.28 +0.40 +0.16 +0.13
2015 2 +0.18 +0.30 +0.05 -0.06
2015 3 +0.17 +0.26 +0.07 +0.05
2015 4 +0.09 +0.18 -0.01 +0.10
2015 5 +0.29 +0.36 +0.21 +0.28
2015 6 +0.33 +0.41 +0.25 +0.46
2015 7 +0.18 +0.33 +0.03 +0.48
Strong July cooling occurred in the Southern Hemisphere extratropics, with a weak drop in the Northern Hemisphere extratropics. The tropics continue to warm with El Nino conditions there.
The global image for July, 2015 should be available in the next several days here.
