Record-warm sea surface temps reported in higher latitudes
By Summit Voice
FRISCO — Global land and sea surface temperatures were both well above average in August 2013, with the month ending in a tie with 2005 as the fourth-warmest August on record, dating back to 1880.
According to the NOAA National Climatic Data Center’s monthly summary, it was the 35th consecutive August with global temperatures running above average.
Land surface temperatures were 1.39 Fahrenheit degrees above average, making it the 11th-warmest August on record, while the global sea surface temperature was 1.03 degrees Fahrenheit above average, tying with 1998, 2003, 2005, and 2009 as the record-highest for August.
Year-to-date global land and sea surface temperatures are running 1.06 degrees Fahrenheit above average, putting 2013 into a tie with 2003 as the sixth-warmest year on record.
Notably, even without El Niño, many parts of the parts of the world’s oceans outside the tropics experience record-warm sea surface temperatures during August, including the Barents Sea in the Arctic region, sections of the western Pacific Ocean, and part of the south central Indian Ocean.
According to the NCDC, most of the world’s land areas experienced warmer-than-average monthly temperatures, including Australia, northern South America, western North America, Europe, and much of eastern Asia. Far eastern China, part of eastern Russia north of Japan, and part of northeastern South America were record warm for the month.
The southeastern United States, Far East Russia, part of South Africa, Paraguay, and Bolivia were cooler than average. No regions of the globe were record cold.
During the southern hemisphere winter, New Zealand reported its warmest August since national records began in 1909, with an average temperature that 3.4 degrees Fahrenheit above the 1971–2000 average.
Australia reported its second warmest average and maximum August temperatures since national records began in 1910, at 2.88 degrees and 4.68 degrees Fahrenheit above the 1961–1990 average.
