Global Analysis - February 2004


Global Highlights:

  • Based on preliminary data for December 2003 - February 2004, global average combined land and sea surface temperature was third warmest on record, and fourth warmest for February 2004
  • December - February temperatures were much above average throughout much of western and central Asia as well as parts of Canada with below average temperatures in northern Australia, Mexico and the eastern U.S.
  • Precipitation during December - February was above average across most of Europe, the Great Plains of the U.S. and northern Australia with drier than average conditions in Ireland, the eastern U.S. and Argentina
  • Near-normal SSTs across the central and eastern equatorial Pacific basin are indicative of neutral ENSO conditions.

Top of Page Introduction

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. Both maps indicate above average temperatures in the central U.S., most of Europe and Japan while cooler than average temperatures occurred in northern Australia and northern Argentina during winter and February 2004.

The mean position of upper level ridges of high pressure and troughs of low pressure (depicted by positive and negative 500 millibar height anomalies during February 2004 and December-February) are generally reflected by areas of positive and negative temperature anomalies at the surface, respectively. For all Global map products see the Climate Monitoring Global Products 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. The map to the left is precipitation anomalies measured in millimeters, the map to the right is the percentage of average (1961-1990) precipitation. During December - February 2004, much above average precipitation fell across the Mississippi Valley in the U.S., eastern Europe and Indonesia. Below average precipitation was observed in Iberian Peninsula, Ireland and India.

  • Sea surface temperatures were near-normal over much of the central and eastern equatorial Pacific (as shown in the adjacent animation of weekly sea surface temperature anomalies). A consensus of indices suggest neutral ENSO conditions. A comprehensive summary of February 2004 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
  • Images of sea surface temperature conditions are available for all months to date during 2004 at the weekly SST page
