Global Analysis - February 2005


Global Highlights:

  • Based on preliminary data, global average combined land and sea surface temperature for December 2004 - February 2005 tied 1999 as the 4th warmest on record. February 2005 was 9th warmest on record.
  • December - February temperatures were above average from northern Europe into Siberia and also covered large parts of southern Asia, Africa, Australia and western Canada. Colder-than-average conditions occurred in much of eastern Canada, northwest Africa, parts of southern Europe and central Asia.
  • Precipitation during December - February was above average over the southwestern U.S., Alaska, and Scandinavia, with drier than average conditions over the majority of Australia, the Pacific Northwest of the U.S., and western Europe
  • Sea Surface Temperatures (SSTs) continued to be above normal in the central equatorial Pacific during February

Top of PageIntroduction

The two maps below use anomalies that were calculated from the Global Historical Climatology Network (GHCN) data set of land surface stations using a 1961-1990 base period. During the boreal winter, there were above average temperatures across Scandinavia, Europe, western Russia, much of Africa, South America, China, Australia, and the majority of North America. Cooler than average temperatures covered much of central Asia, Spain, Algeria, and northeastern Canada. During February, there were above average temperatures over the entire continent of North America, southern Africa, Argentina, Scandinavia and northern Siberia and cooler than average temperatures across the Iberian peninsula, Mongolia, most of West Africa and Kazakhstan.

The mean position of upper level ridges of high pressure and troughs of low pressure (depicted by positive and negative 500 millibar height anomalies on the February 2005 and the December 2004 - February 2005 maps) are generally reflected by areas of positive and negative temperature anomalies at the surface, respectively. For other Global products see the Climate Monitoring Global Products page.

Images of sea surface temperature conditions are available for all weeks during 2005 at the weekly SST page

Top of Page Precipitation

The maps below represent anomaly values based on the GHCN data set of land surface stations using a base period of 1961-1990. During December 2004 - February 2005, above average precipitation fell across parts of Alaska, the Great Lakes region of the U.S., Japan and South Africa. Below average precipitation was observed in the Pacific Northwest and southeastern region of the U.S., the majority of Australia, western Europe, Thailand, and most of Brazil. During February, above average precipitation fell in southeastern China, southwestern U.S., Bolivia, eastern Europe and northern Mexico, while below average precipitation was observed in Australia, Indonesia, southern portions of Brazil and the Pacific Northwest of the U.S.

  • SSTs continued to decrease in the eastern equatorial Pacific, but remained above normal in the central and western equatorial Pacific during February (shown in the adjacent animation of weekly sea surface temperature anomalies), as a weak warm phase ENSO (El Niño) continued . A comprehensive summary of February 2005 ENSO conditions can be found on the ENSO monitoring page. For the latest advisory on ENSO conditions go to NOAA's Climate Prediction Center (CPC) and the CPC ENSO Diagnostic Discussion
