Friss MetOffice Winter forecast: Link

Összefoglalás:
- the latest signal from model(s?) is similar to that in October: positive NAO for DJF 2014/15
- not clear which driver may be responsible for this response in models; most drivers which are in an active phase would typically favour the opposite
- early indications (but how skilful?) of potential for stratospheric warming later this winter, and thus of change from positive NAO
Overall, no clear-cut conclusion.
