El Niño



Most people probably know what El Niño is, but for those who don't this Met Office video is a good, straightforward presentation. It also covers La Niña. If it is as strong as predicted the it may well be blamed for many natural disasters, sometimes truthfully, sometimes not.

It's clear, but I don't get why the trade winds should be disrupted in the first place. If the system across the Pacific tends towards self-perpetuation, what mucks it up?

Sam - that bit is more complex which makes El Niño events difficult to predict in the medium to long term. Various circulation patterns change as if the whole system is reaching a state of instability.

Naaah, we're only 'told' there is instability!

Why bother listening to these people? Their income thrives on bollocks, and they know it!

Me? I'm just a lawnmower, you can tell me by the way I walk....

(That's Genesis; 'Selling England by the pound', but you almost certainly know that...)

What I want to know is where I put my umbrella.

Michael - their income certainly does thrive on bollocks, it's a growth industry.

Demetrius - it's with your gloves.
