Can you have fog inside?

As per title really. I can't remember ever having seen fog inside and the only references I've ever heard alluding to it where about Albert Speers proposed super dome and the Foundry at Dagenham which I would assume would be smoke of steam rather than fog.

Only ever seen it in large film studios where the sides hadn't been finished and it rolled in off the neighbouring fields.

The huge Saturn V construction building at Cape Kennedy did get clouds in it.

Not since they banned smoking in pubs.

Fog inside?

I've seen it in sheds and house in San Francisco.

The fog rolls in over the mountains on the coast and falls like a heavy cloud, down the sides and into the bay. It's like one of those volcanic things, engulfing all in its path. Very eery and spooky. This was on the north bay area, Andersons Boatyard in north Sausalito.

Cheers,
Nev.

Just about every plane landing in Dubai in the summer has mist inside due to the high humidity and a/c cooling.

Fog is mist on dust particles

you can when its green and eery, but it takes control of your brain and turns you into a zombie killer, watch out for zombie pigeons, they can be lethal!

Confused but excited. - 1/10/11 at 11:46 AM

In fact enough to make it rain.

You can get fog even in very small enclosures, with the right conditions, ie; a cloud chamber.

Not sure you would notice fog in most buildings though. They are not big enough. Isn't fog when visibilty is less than 1km? OK, can be a lot less, but it needs a big space.

Heater matrix blew at 70 mph in my old Citroen. Immediate heavy mist on screen so not much visibility and the car filled up with fog

I've seen clouds in a building. The old hangars at Cardington where they kept (keep?) the airships.

Back in 1989 we did a rally that started inside the building. It was so big that all the competitor's cars and all the service and support vehicles were inside and there was still loads of room left.

Fog is just a cloud that's near to the ground (with certain visibility parameters for it to be classed as such).
Cloud, (fog) formation relies on the presence of moisture (droplets), temperature, pressure and volume. Dust or smoke particles help the water vapour to more easily coalesce into droplets and thus form clouds/fog.
It's all derived from the Ideal gas Law (PV=nRT). R is a constant, (It's 30 years since I did this guff in meteorology as an aviator).
You can get clouds in buildings provided you manipulate the variables, moist air, rapid cooling, reduction in pressure. In fact you can get a cloud in a bottle by using a plastic bottle where by squeezing and releasing, you can artificially increase and decrease the pressure, whilst 'fixing' the other variables.
I knew this stuff would come in useful one day.

Used to work in them myself and yes in the right conditions you could get a bit of mistyness at the top. Cool buildings.

I've seen it in indoor ski slopes but not very dense.

David Jenkins - 1/10/11 at 05:52 PM

I'm going to show my age now...

I have a distant recollection of looking down the stairs (indoors) and not being able to see the bottom due to a mucky yellow fog...

It would have been around 1953, when my family lived in Surbiton - during one of the last of the London smogs. I would have been about 1 year old. It's one of my oldest recollections, in the back of my subconscious...

...I feel old now.

Thanks for the answers.

Have had pretty dense fog roll into an aircraft hangar up here in glasgow.

It was dense enough to set off the cargo smoke detection system alarms on the aircraft we working on. Certainly woke up a few people
