Global Analysis - February 2002


Global Highlights:

  • *Global average land and sea surface temperature was the second warmest on record for February and boreal winter (December-February)
  • Lower tropospheric temperatures were warmer than average for February and boreal winter
  • Temperatures in the lower stratosphere remained cooler than average
  • During December-February, above average precipitation was most notable across western Europe and parts of Bolivia and Brazil, with below average precipitation across much of the U.S. and the Mediterranean region

Top of Page Introduction

Using a 1992-2002 base period as shown in the adjacent blended temperature product of satellite and in-situ data, anomalous warmth during the period December-February in the Northern Hemisphere was closely associated with the location of upper level ridges of high pressure. These ridges of high pressure (depicted by positive 500 millibar height anomalies) were centered across mid-latitude areas. Temperature anomalies calculated from in-situ station data using a 1961-1990 base period also show the warmer than average temperatures in these regions with cooler than average temperatures restricted to much of Australia and the Russian Far East. The temperature distribution across Asia was highlighted by a large area of above average warmth during February. Click Here for the Global Blended Temperature in December-February 2002

Top of Page Temperature

  • A slow evolution toward warm ENSO conditions continued in February 2002, and the global land and ocean temperature was the second warmest in the 1880-2002 record or 0.71°C (1.28°F) above the long-term average
  • Temperatures averaged across land areas were also second warmest on record globally, or 1.39°C (2.50°F) above the long-term February mean
  • Record warmth was noted across extratropical areas of the Northern Hemisphere, where combined land and ocean temperatures were 1.35°C (2.43°F) above the 1880-2001 average

  • Based on data available at the time of this report, the global average land and ocean temperature for boreal winter (December-February) was 0.59°C (1.06°F) above the 1880-2001 mean, the second warmest winter season on record
  • During December-February, temperatures in the Northern Hemisphere, also ranking as second warmest, averaged 0.76°C (1.37°F) warmer than the average
  • Global land temperatures were third warmest for boreal winter, or 0.96°C (1.73°F) above the mean
  • Serial monthly global surface temperature departures with respect to a 1971-2000 mean are shown in the figure to the right
  • The recent return to record or near record temperature departures is evident, as monthly global temperatures (land and ocean) have been warmer than the 1971-2000 average for the last 70 consecutive months

Top of Page Precipitation

  • During December-February, much above average precipitation fell across parts of Brazil, Bolivia, Indonesia and western Europe
  • Drier than average weather prevailed across much of the U.S., the Argentinian Pampas, and the Mediterranean region
  • A similar precipitation pattern was observed during February 2002
