    Would someone like to explain the conditions/climate that lends itself to this persistant fog. On M 50 and only few hundred meters visibility, not driving

    Fog forms once evaporation into the air results in supersaturation. If the dewpoint depression is small after sunset, clear skies will cause radiational cooling of the air quickly toward saturation. The dewpoint can increase due to a rain shower, previously saturated soils and irrigation. Since vegetation and bodies of water evapotranspirates moisture, fog first forms over grassy and nearby rivers, lakes or seas. Fog is common in situations where a daytime shower saturates the soil, vegetation and boundary layer and then skies clear in the evening into the night hours.


    Low layer inversion is capping any of that mositure to rise up higher...

    Winds picking up later will help clear the fog in most areas by tomorrow.

    Surprisingly it seems to be a bit clearer now that its dark. Or maybe its not surprising as I don't know the science of it well enough. Or possibly its just because lights are easier to see through fog than unlit concrete?

    With south-easterly winds set to freshen overnight, the fog won't last too long

    Fog was absolutely ridiculous on the N20 from the N20/M20/N21 interchange to Charleville yesterday around 2:30. Was difficult to even see the car in front. Visibility was grand until I left the M20 and climbed up onto the N20 at the interchange

    Cockpit view of automatic landing in fog at Dublin airport.

    Net Zero means we are paying for the destruction of our economy and society in pursuit of an unachievable and pointless policy.
