It isn't JB talking about it, but it's Accuweather.
Oh ... my ...
All right. I watched it, and all I can say is what a honkin' load of hogwash!
First of all, the NOAA outlook was for a 50% chance of a weak el Nino commencing
by the end of the year - but the Accuweather guys didn't say that they just said 50% and then launched right into how they've been saying it's already happening. This was a deceptive attempt to pretend that the CPC outlook supports what they're saying when in fact CPC says neutral conditions for the next three months
at least with a gradual trend indicating 50% chance of a weak el Nino by year's end.
Second, a negative SOI is far from all there is to an el Nino. In fact, the only reason a negative SOI is significant to an el Nino is because generally that correlates with a westerly anomaly in the equatorial trade winds and resulting warm anomaly in the Nino 1,2 SSTs. But that response has been weak at best and the recent trend is not indicative of any strengthening of the effect. As the most recent BOM update said:
At odds with the mainly neutral setting is the Southern Oscillation Index (SOI), which has dipped below −10 during the past week as a result of well above average air pressure at Darwin, and consistently below normal air pressure at Tahiti. This indicates a general weakness in the Pacific Walker Circulation. However, the Trade Winds have increased to somewhat above average strength during the past week after being suppressed for much of July. There was little response to the weakened July Trades in ocean temperatures, and these remain somewhat above average, both on and below the surface. Therefore there is only a slight risk that the Pacific will warm to levels high enough for an El Niño event to develop.
That was just ridiculous.
