  2. I. The Tropics

  3. The latest weekly SST departures are: Niño 4 0.3ºC Niño 3.4 0.4ºC Niño 3 1.0ºC Niño 1+2 1.4ºC Niño Region SST Departures (oC) Recent Evolution

  4. During the last four weeks, above-average equatorial SSTs were observed across the Pacific and near Indonesia. Global SST Departures (oC) During the Last Four Weeks

  5. During the last four weeks, changes in equatorial SST anomalies were negative near the International Date Line and positive in small areas of the eastern Pacific. Change in Weekly SST Departures over the Last Four Weeks

  6. Subsurface temperature anomalies increased during June, August, and in October 2013. From January - March 2014, temperature anomalies strongly increased. Since April 2014, the positive anomalies have weakened and are now near zero. Weekly Central & Eastern Pacific Upper-Ocean (0-300 m)Average Temperature Anomalies

  7. Most recent pentad analysis Positive subsurface anomalies are evident near the surface (<100m) across most of the Pacific basin, while negative anomalies have strengthened in the central and east-central Pacific at depth. Sub-Surface Temperature Departures in the Equatorial Pacific

  8. Updated: July 10 2014 The chance of El Niño is 70% during the Northern Hemisphere summer and reaches near 80% during the fall and winter. CPC/IRI Probabilistic ENSO Outlook

  9. Most models favor El Niño (greater or equal to +0.5ºC) to develop in the next several months and persist through Northern Hemisphere winter 2014-15. IRI/CPC Pacific Niño 3.4 SST Model Outlook Figure provided by the International Research Institute (IRI) for Climate and Society (updated 17 June 2014).

  10. Summary ENSO Alert System Status: El Niño Watch ENSO-neutral conditions continue.* Sea surface temperatures (SST) are above-average across the equatorial Pacific Ocean. Tropical rainfall is slightly enhanced over Indonesia and near the International Date Line. Chance of El Niño is 70% during the Northern Hemisphere summer and reaches 80% during the fall and winter.* * Note: These statements are updated once a month in association with the ENSO Diagnostics Discussion, which can be found by clicking here.

  11. The mythology of MJO

  12. Ensemble GFS (GEFS) MJO Forecast Yellow Lines – 20 Individual Members Green Line – Ensemble Mean RMM1 and RMM2 values for the most recent 40 days and forecasts from the ensemble Global Forecast System (GEFS) for the next 15 days light gray shading: 90% of forecasts dark gray shading: 50% of forecasts The ensemble GFS forecast indicates a strengthening signal with eastward propagation of the MJO RMM Index over the Maritime Continent during the next week. Most ensemble members weaken the signal considerably during Week-2.

  13. II. The Extra-Tropics

  14. III. Verification of AMJ & June 2014 Outlooks
