The globally averaged surface temperature anomalies for the season, as shown on the time series graphs above, indicate continued warm temperatures during the September through November period. The combined land and sea surface temperature anomaly for this period was 0.40 C above the 1880-1998 mean but was 0.20 C less than the record 1997 value. Sea surface temperatures were 0.31 C below 1997 levels, while land temperatures were only 0.07 C less than the highest anomaly recorded in 1998.

| The adjacent figure shows September through November 1999 temperature anomalies calculated from available in-situ stations using a 1961-1990 base period. Temperatures were above normal over most of the world's land areas. Exceptionally warm anomalies over 5 C were observed in Scandanavia and northern Canada. Warm anomalies of 3 to 5 C were observed at many sites in the 40 to 60N latitude band. Below normal temperatures were reported over Alaska, Brazil and northern Asia. |  |
Global Precipitation

The adjacent map shows the September through November precipitation anomalies from the 1961-1990 base period. Observations from the western two-thirds of the United States show less than average precipitation, with exceptionally dry conditions in the central United States.
| Exceptionally dry conditions were also observed in Uruguay, eastern Argentina, and at several tropical Pacific island locations. Several areas were wetter than average. Continental east coastal areas in the northern hemisphere were much wetter than normal in response to tropical storm activity. Other areas that experienced anomalously wet conditions include central Europe, parts of Asia, and west central Africa. Additional information is available on the Global Regional Analyses pages. |
