1. 2009 global climate: A tale of five timeseries Global mean temperature El Ni ñ o / Southern Oscillation (ENSO) Pacific Decadal Oscillation Annular modes north and south Todd Mitchell, Climate Impacts Group February 2010

2. 0.56 °C in 2009 (tie with 2006 for 6th warmest, 1901-2000 mean)

3. The decade 2000-09 was the warmest on record (0.54C). 2005 the warmest, followed by 1998 the 2000-09 decade is the warmest on record

4. Southern annular mode positive early in 2009

5. central - southeast Australia drought continues tropics not typical warm ENSO signal wet Mediterranean consistent with negative NAM, NAO

6. El Niño / Southern Oscillation (ENSO) with respect to 1971-2000. 1.04, 1.67, 1.83 °C in October, November and December, respectively 0.46°C 2009-mean, October-November-December mean 1.48°C 3 Atlantic hurricanes this year (fewer hurricanes during warm ENSOs)

7. Warm ENSO peaking now and will diminish through May-June- July

8. 1900-93 climatology 2009 mean -0.6 standard deviations NOAA coupled forecast model predicts positive PDO (warm west coast SST anomalies) through the Spring

9. Northern annular mode December 2009 largest negative value since at least 1950. January through December averages

10. Typical Northern Annular Mode temperature and preciptation anomalies

13. central - southeast Australia drought continues tropics not typical warm ENSO signal wet Mediterranean consistent with negative NAM, NAO

14. minimum in September September 2009 the 3rd lowest since 1979

15. 1895-2008

17. Record warm Seattle July Cool and wet in central and eastern U.S. Modeling studies suggest this pattern was related to tropical SSTs

18. U.S. Wildland Fires

19. February-March- April temperature forecast: Enhanced probability of warmer than normal temperatures in the Pacific Northwest (classic ENSO pattern)

20. February-March- April preciptation forecast: increased probability of drier than normal in the Pacific Northwest (classic ENSO pattern)
