00:00Current forecasts suggest no significant UK cold or snow is likely soon.
00:04But why are snow rumors spreading for this autumn and winter?
00:08El Niño, a natural Pacific climate pattern, increases chances of mild wet UK autumn weather.
00:14Yet later in winter, it could favor cold and snow.
00:18That's partly through the polar vortex.
00:20When circling the North Pole, they blow 1030 miles above Earth, far above our weather.
00:25A strong vortex tends to keep the coldest air north of the UK.
00:29But over days or weeks, a weakening vortex can influence the jet stream.
00:34That may bring colder winds, but surface weather does not always change.
00:38And evidence linking El Niño to winter snow remains mixed.
00:42The UK's 2009-2010 winter was then its coldest in three decades.
00:47But the 2006-2007 El Niño winter was unseasonably warm.
00:52So El Niño offers no guarantee behind those UK snow rumors.
