Prop Vortices

I was browsing through some photos when I found a handful with prop vortices. I was wondering how to get this effect in pictures or if it is an isolated occurance, maybe perhaps controlled by atmospheric conditions such as temp/humidity. Thanks for any help!

Photographically, there's no way to 'get' prop-vortices. Rather, whether they form visibly or not simply depends on atmospheric conditions.

It's been my experience that I've seen prop vortices during very high humidity conditions. This doesn't always mean they'll appear, but that's when I've seen them most.

Sometimes you have and sometimes not. Depends on the weather, mostly when it's very wet.

Here are my additions.

Thanks for the replies! The Blue Angels are coming to town this weekend and hopefully it'll be humid enough for Fat Albert to get some vortices off the props.

My experience is that it often occurs on rainy days. Light rain in the air, and most props I've seen taking off get them nice vortices. Unfortunatly, I have never managed to get a proper shot of that happening yet.

Just returned from my UK holiday btw, MAN was great. Big grin

You do have a better chance of witnessing this phenomenon when the dewpoint is higher, not so much the humidity. In that, if someone could offer some sort of insight on how the hell my C-2 Greyhound photo has that much condensation at North Island, I am all ears. It damn sure wasn't sticky.  Confused

Lots of moisture in the air that day... Sunshine and heavy showers.

Everyone keeps referring to the word 'vorticy' yet that isn't even in the dictionary. I believe the correct word is vorticity:

Physics. A measure of the rate of rotational spin in a fluid.
Meteorology. A measure of the spin of an air mass such as a low- or high-pressure weather system

Feel free to correct me if this is a 'slang' word for aviators or something...

I think prop "vortices" are the same effect as those condensation trails you sometimes see from flaps or wingtips etc. If I remember right (in most cases I don't), the temperature and dewpoint should be close to each other for this visible condensation to form.

It's not aviation slang at all. It's in the American Heritage dictionary at www.dictionary.com and has four entries for the word "vortices." "Vortices" is the pluralization of the word "vortex."

I would copy the entries here but there's a copyright notice.

Where is it spelled "vorticy" as you state? I just did a quick check of the above, including the photo descriptions and I don't see anyone spelling it like you said we did.
