There were rarely any definitive indications in any of the medium (GFS, ECM) or long term models (glosea for instance) of a significant cold spell in March/April. Most of the pre-season submissions suggesting a 'late winter' were based on a blend of trends, with El Niño high on the list of influences, and many were backed-up by a decent evidence base and reasoned arguments. Some contributors are heavily biased towards the as yet little understood influence of SSW events in the northern hemispheric stratosphere, and I cite Cooling Climate as one of those, to the point of criticising anyone who suggested otherwise, including the Ukmo (monthly text outlook updated daily) who he suggested didn't know what they were talking about in saying a significant N or NE spell was a very low probability. I've learnt over the years that the weather prediction business is way too complex to be putting all your eggs into one basket.
Cooling Climate may well of been correct with his 'SSW will deliver significant cold to the UK' forecast, but despite his claims I do understand the nascent science of SSWs to a reasonable degree, enough to suggest if he had been correct it would be more by luck than judgement.
