Strange Cloud hanging over the bay

Geographe Bay

Geographe Bay

 

Had some great cloud around last week. Mark Stothard and I were shooting Castle Rock when this cloud appeared. Weird one, anyone know the name of this sort of cloud?

    Hi Christian, interesting cloud, Cumulus of some sort and probably unoficially known as a ‘roll cloud’. most oftrn seen with frontal activity or thunderstorms. if I was on the yacht I would keep well clear of it!

  2. Nice little outflow feature there CF – This type of cloud (gust front, guster, scud,rollcloud etc) is generally caused by colder air from an approaching storm being pushed out ahead of the storm (the air is dragged down from aloft by the rain). It hits the ground/ocean and is forced forward where it meets warmer air and condenses – forming the low cloud that you see. Usually as this hits you, there will be a cooler blustery breeze…some time shortly after it will rain as the approaching storm then reaches you.

        Tony Middleton is spot on. These clouds are called Morning Glories, are suppose to only form in 2 places, one is the Gulf of Carpentaria, and the other i forget where, Northern Hemisphere somewhere. But we know that’s not true, we get them occasionaly come across Port Philip Bay, before it gets to you, the wind is very strong as you witnessed. People use hang gliders to surf the Glories in the Gulf, up to 300 kph’s wind there.
