• Is haze like that always caused by pollution? Seemed really misty last night, even in the 'burbs... was hoping it was just natural mist.

  • It's either going to be water vapour or particulates (or both), I guess.

    Anyway, LondonAir is at Moderate. The forecast suggests the wind is bringing particulates from the continent to the East, and they're hanging around rather than dispersing.

    Anyway, I Am Not A Meteorologist, I just look at that to see how nasty the air's likely to be.

  • It's not always caused by pollution, other causes are things like pollen, smoke, some photochemical gaseous shite that's been emitted somewhere (not necessarily anthropic - plants, microorganisms, volcanoes, whatever), dust, etc. Probably plain old pollution in this case.

    (I'm also not a meteorologist.)
