Climate bulletin - March 2013
Summary of the world's climate in March 2013.
The global average temperature for March 2013 was 0.41 ± 0.16 °C above the 1961-1990 average (down slightly from February). Sea-surface temperatures in the Tropical Pacific remain close to the long-term average. Together with other atmospheric indicators, this is consistent with ongoing neutral El Niño Southern Oscillation conditions.
In March, temperatures were well below average across northern Eurasia, from the UK (where the March Central England Temperature was the lowest since 1892) to China. In contrast, north Africa and southern Eurasia were warmer than the long-term average. Contrasting temperatures were also observed across north America with above average temperatures in the western US and eastern Canada and below average temperatures in the east of the US and western Canada.
Sea-surface temperatures in the north Atlantic remained generally above average, reflecting the ongoing warm phase of the Atlantic Multi-decadal Oscillation. However, the Baltic Sea and North Sea were colder than average after the sustained below-average air temperatures during February and March. In the north Pacific, a horseshoe-shaped area of cooler than average sea-surface temperatures surrounding an area of above average SST is still in evidence.
