Global Analysis - June 2006


Global Highlights:

  • Based on preliminary data, globally averaged combined land and sea surface temperature was 2nd warmest on record for June 2006.
  • June temperatures were above average in Europe, Canada, the Middle East and the majority of the U.S. Colder-than-average conditions occurred in the far western coast of Alaska and the coast of Brazil.
  • Precipitation during June was above average in the U.S. northeast, Chile, Indonesia and Taiwan, with drier-than-average conditions in the U.S. southern Plains, much of the Amazon Basin and western Australia.
  • ENSO conditions remained neutral during June.

Top of PageIntroduction

Temperature anomalies for June 2006 are shown on the two maps below. The dot map on the left provides a spatial representation of anomalies 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 product of a merged land surface and sea surface temperature anomaly analysis which is based on data from the GHCN of land temperatures and the Comprehensive Ocean-Atmosphere Data Set (COADS) of Sea-Surface Temperature (SST) data. Temperature anomalies with respect to 1961-1990 for land and ocean are analyzed separately and then merged to form the global analysis. Additional information on this product is available.

During June, there were above average temperatures across Chile, Europe, Scandinavia, the Middle East, Russia and the majority of North America. Cooler than average temperatures were observed in the far western coast of Alaska, North Korea, Pakistan and the coast of Brazil.

During January-June 2006, there were above average temperatures in the majority of North America, China and western Europe. Cooler than average temperatures were observed in Alaska, far eastern Europe, and parts of Russia.

In January-June and June, warmer than average SSTs occurred in the South Pacific and the North Atlantic. In January-June, cooler than average conditions were observed in the Niño 3.4 region, and the western coast of Australia. In June, cooler than average conditions were observed in the North Pacific and South Atlantic. Please see the latest ENSO discussion for further information.

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 2006 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.

Images of sea surface temperature conditions are available for all weeks during 2006 at the weekly SST page.

Top of Page Temperature Rankings and Graphics

Effective with the January 2006 report, NCDC transitioned from the use of the Operational Global Surface Temperature Index (Quayle et al. 1999) to the blended land and ocean dataset developed by Smith and Reynolds (2005). The differences between the two methods are discussed in Smith et al. 2005.

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 2006, above average precipitation fell over areas that include Alaska, the U.S. Northeast, eastern Australia, southeast Asia and Chile. Heavy rain and flooding occurred in southern China, India, Indonesia, the U.S. Northeast and Mid-Atlantic and Romania. Below average precipitation was observed throughout the Amazon Basin, Europe, most of India, the U.S. Great Plains, and western Australia. Additional details on flooding and drought can also be found on the June Global Hazards page.

  • Sea Surface Temperatures increased across most of the equatorial Pacific Ocean during June, but ENSO remained in a neutral state (shown in the adjacent animation of weekly sea surface temperature anomalies). A comprehensive summary of June 2006 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 weeks during 2006 at the weekly SST page
