Global Analysis - June 2005


Global Highlights:

  • Based on preliminary data, global averaged combined land and sea surface temperature for June 2005 was 2nd warmest on record.
  • June temperatures were above average over Alaska, the U.S. Great Lakes region, most of Canada and western Europe. Colder-than-average conditions occurred primarily in the northwestern U.S., western Australia, southern Argentina and parts of Mexico.
  • Precipitation during June was above average over the eastern U.S., the Caribbean and western Europe, with drier than average conditions over much of Asia, the majority of Australia and Alaska.
  • Neutral ENSO conditions continued during June.

Top of PageIntroduction

Temperature anomalies for June 2005 are shown on the two maps below. The dot map on the left uses anomalies that were calculated from the Global Historical Climatology Network (GHCN) data set of land surface stations using a 1961-1990 base period. The map on the right is a weekly product based on data from the Comprehensive Ocean-Atmosphere Data Set (COADS) of SST data. During June, there were above average temperatures over much of the eastern half of the U.S., Alaska, Canada, southern Brazil, western Europe, eastern Australia, southeastern Asia, India, Siberia and Japan. Cooler than average temperatures were observed over the U.S. Rocky Mountains, eastern Australia, Afghanistan, Pakistan, parts of the Caribbean and Scandinavia.

Above average SSTs are evident in the product above. Much warmer than average anomalies occurred over the northern Atlantic, the northern Pacific, particularly off the coast of Alaska as well as the over the Mediterranean Sea. Slightly warmer than average temperatures were observed over the eastern and central Pacific, indicating a continuation of neutral ENSO conditions. Cooler than average SSTs were observed off the coasts of Ecuador and Peru and the western tropical coast of Africa.

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 June 2005 map) 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.

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 June 2005, above average precipitation fell over the U.S. northern Great Plains, the southeastern U.S., the Caribbean, Colombia, southern Chile and Argentina, southeastern Asia and the majority of Australia. Below average precipitation was observed over the U.S. southern Great Plains, northern Mexico, much of Europe, India and Japan.

  • SSTs remained near average to slightly above average in the eastern equatorial Pacific during June, indicative of ENSO neutral conditions (shown in the adjacent animation of weekly sea surface temperature anomalies). A comprehensive summary of June 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
