Temperature

The September-November 2000 combined land and ocean temperature was +0.36C above the 1880-1999 long-term mean, the 8th warmest on record. The globally averaged temperature during this period has not averaged below the long-term mean since 1976, indicative of a trend to warmer global temperatures that began in the late 1880's. Ocean temperatures were also much above average during this period (+0.36C), the 4th warmest such period on record, while land surface temperatures were the 13th warmest, +0.35C above average.

The adjacent plot shows the spatial distribution of temperature anomalies throughout the world based on a 1961-1990 base period. Above average temperatures were widespread throughout the Northern Hemisphere during the September through November period. Temperatures were from 1 to 3C above average across south central Europe and anomalies of 4 C were noted across Scandinavia.

The coolest anomalies were also in the Northern Hemisphere in central Siberia, north of Mongolia, and in parts of the northern Rockies in the United States. Anomalies in these region were 2 to 4 C below average. Anomalies were generally mixed across land areas in the Southern Hemisphere.

Precipitation

The adjacent plot shows precipitation departures for the September-November period. Drier than normal conditions were predominant throughout parts of the northeatern U.S and the Pacific Northwest coast of the U.S., along with parts of eastern Europe and northern Scandinavia. Drought caused some problems across parts of eastern U.S. as well.

Widepsread areas of above average precipitation covered portions of western and central Europe and across eastern Asia. Precipitation was also above average in southeast South America and in northeastern Australia. Localized flooding caused some damage in these areas as well this season.
