November 2005 Global Climate Report | National Centers for Environmental Information (NCEI)

Global Highlights:

Based on preliminary data, globally averaged combined land and sea surface temperature was warmest on record for September-November 2005, third warmest on record for November.
September-November temperatures were above average across much of the Globe including areas in North America, Asia, Europe and the majority of the African continent. Colder-than-average conditions occurred in Bolivia, Turkey, Iceland and western Australia.
Precipitation during September-November was above average in the northeastern U.S., Alaska, the Caribbean, Scandinavia and India, with drier than average conditions in eastern Europe, southeast Asia and the southern U.S.
Neutral ENSO conditions continued during November.

The data presented in this report are preliminary. Ranks and anomalies may change as more complete data are received and processed. The most current data may be accessed via the Global Surface Temperature Anomalies page.

Introduction

Temperature anomalies for September-November and November 2005 are shown on the four maps below. The dot maps 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 maps on the right are an experimental blended product of a merged land air 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 the boreal fall, temperatures were more than 3°C above average across large parts of Europe, Russia, China and much of North America. Cooler than average temperatures were observed in Iceland, Turkey, the U.S. Pacific Northwest, western Mongolia, and western Australia.

Warmer than average SSTs occurred over the North Pacific and North Atlantic. Cooler than average conditions were observed off the coasts of Ecuador, Peru, California and in the Niño 3 region.

During November 2005, there were above average temperatures over Scandinavia, Russia, eastern China, eastern Australia and the majority of North America. Cooler than average temperatures were observed over Alaska, Peru, the Iberian Peninsula, southern portions of Europe and the U.S. Pacific Northwest.

Warmer than average SSTs occurred in the North Pacific and the North Atlantic. Cooler than average conditions were observed in the Niño 3 and 3.4 regions and the South Indian Ocean.

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 September-November 2005 map and the November 2005 map) are generally reflected by areas of positive and negative temperature anomalies at the surface, respectively.

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 the 2005 boreal fall, above average precipitation fell over areas that include Alaska, the Caribbean, India, the Philippines, Norway, Peru and the northeastern U.S. Below average precipitation was observed in Eastern Europe, the southern U.S., southeastern China and coastal Brazil.

During November 2005, above average precipitation fell over areas that include India, Peru, Colombia, parts of Eastern Europe and the U.S. Upper Great Plains. Below average precipitation was observed in the Philippines, southeastern Asia, the southern U.S, Mozambique and most of Brazil.

SSTs remained near average to slightly below average in the equatorial tropical Pacific during November, indicative of ENSO neutral conditions (shown in the adjacent animation of weekly sea surface temperature anomalies). A comprehensive summary of November 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
Images of sea surface temperature conditions are available for all weeks during 2005 at the weekly SST page
