Climate bulletin - March 2014

Summary of the world's climate in March 2014.

The global average temperature for March 2014 was 0.54 ± 0.17 °C above the 1961-1990 average. Sea-surface temperatures (SSTs) in the Tropical Pacific remained close to the long-term average, and together with other indicators, conditions remained El Niño-Southern Oscillation (ENSO) neutral.

During March, the global average air temperature over land was warmer than the long-term average (0.93 ± 0.32 °C). Large areas of eastern North America were colder than average with the area north of the great lakes being unusually cold. Parts of South America were also unusually cold. Areas of unusual warmth included the west coast of the USA, much of Europe and areas of Eurasia, with an area near Beijing recording temperatures that exceeded the 98th percentile.

SSTs were generally warmer than average in March (0.34 ± 0.09 °C). Large areas of unusual warmth were recorded in the north-east Pacific, parts of the North Atlantic, Indian Ocean, South Atlantic, Mediterranean and western tropical Pacific. Areas of unusually cold waters were more limited. Notably, the great lakes were unusually cold following five months of below average temperatures (November 2013 - March 2014). Areas of the north Atlantic were also unusually cold including a region around 30 °W at the same latitude as Ireland and an area off the west coast of north Africa.

Parts of the Tropical Pacific were also unusually cold, but observations from this region have been less reliable in recent months due to the failure of a number moored buoys in the  TAO/TRITON array.
