December has been a fail for BoM 70% prediction of El Nino as SOI rises and eastern Australia gets rain

For all of 2014 now an assortment of warmists have sounded fanfares about the upcoming El Nino – even “Super El Nino” – prayer mats out begging the weather gods to deliver them a year hotter than 1998. But both the 30 & 90 day SOI has been rising for a month – nothing is surer than another El Nino will lurch onto the stage sometime – just has not obliged warmists by turning up this year. Rain for December.

The Southern Oscillation Index (SOI) muddles around again getting further from threshold El Nino conditions

Starting in January we have had no shortage of news items from warmists predicting an El Nino event this year – even a “super El Nino”. However despite all the media hoopla – the SOI has not gone below -10 for long enough to ring the bell on an El Nino event. On 18th November 2014 the BoM in their ENSO update which looked at a range of conditions in the Pacific – opted for “…at least a 70% chance of El Niño occurring.” – but they fail to say when.
As I write both the 30 day and 90 day SOI are above minus 8 and rising – just as there is no show without Punch – there will be no El Nino without a strongly negative SOI.

If strong winds are behind the pause in global warming – would weaker winds cause global warming?

According to the ABC – a recent article by Professor Matthew England University of New South Wales – has claimed – “…stronger than normal winds in the Pacific are the explanation for a pause in global warming…”
I just thought I would open this for discussion here.
Does anybody know of long term land based wind observations in the tropical Pacific.

Another example of a possible drift in early TOMS satellite ozone data

I have looked at the ozone hole issue a few times over the years – and have had a suspicion that various factors affect stratospheric ozone levels apart from destruction wrought by gases released from old fridges and freezers.
In the previous post the graphic indicates that ozone and temperature could be more congruent in the early years 1978-1985.
Out of curiosity I compared TOMS monthly data ex KNMI to the Arosa ozone series from Switzerland.

Lo and behold – TOMS numbers look too large in the early years too.
The KNMI TOMS series is a blend with more recent data from the European Space Agency SCIAMACHY ozone data. TOMS having ended in 2007.

Linking the origins of Typhoon Haiyan to warm sea surface temperature anomalies is far from convincing

The Sydney Morning Herald ran this article – Typhoon Haiyan influenced by climate change, scientists say – there must be hundreds of articles written along the same general drift. In this case a map of sea surface temperature (SST) anomalies is presented by the SMH for the period 3rd to 5th Nov.

Note the location of the warm anomaly is from 160-165 East and between 5 South & 5 North.
Here is a map of Typhoon tracks including the Haiyan path extended as far east to its origins as I can find.

Note that Haiyan originated in the grid box 155-160 East and 5-10 North. A fair distance from the grid box where the weak SST anomalies highlighted in the SMH article were supposed to cause the Typhoon to form.
Note also that the storm moved westwards to near 145 East before the windspeeds attracted attention and the Typhoon was reported.
At this NOAA site you can make SST anomaly maps for 3 or 4 day periods and personally I am not seeing SST anomalies that stand out as being exceptional in late October – early November.
I have been looking for an animation of the jet streams in that region, no luck so far. I thought this page was interesting discussing the Madden-Julian oscillation.
