The latest ENSO wrap up from the Australian Bureau of Meteorology indicates that the El Niño is likely to continue to strengthen, with trade winds weakened or reversing.
The 2015 El Niño continues to develop. Weakened (or reversed) trade winds have resulted in further warming over much of the tropical Pacific Ocean. All key ENSO ocean monitoring areas have been more than 1°C above average for 10 successive weeks—two weeks longer than the record in 1997. The eastern tropical Pacific is now at or exceeding +2°C. In the atmosphere, the past week has seen the Southern Oscillation Index (SOI) drop to around -20, the lowest values of the event so far.
Warning to the bandwidth challenged - one of the files below the fold is rather large (just under 1 MB).
The model outlook from BoM shows the likely strengthening of El Nino, with not that much of a spread between models:
Next an animation of sub-surface temperatures in the equatorial Pacific, down to 400m, starting in January 2014 through to June 2015. This year is different to last year. These are from BoM.
Here's an animation of sea surface temperatures across the Pacific, from NOAA images from January this year through to 20 July:
Below is the latest image of sea surface temperature anomalies in the Pacific, with markups (by me not NOAA). Hot spots are popping up all over:
There's more to impress, from Earth sea surface temperatures and currents. Yellow is hot!
