How can a human body create such effects on a freezing cold winter day?

I was in doubt if this is the right chapter to place this thread, but it seems there are many talents just here.

"we were observing from a decent distance through optics. The weather was frosty, clear, calm. When хххххх appeared from under the arch of the house (he was хххххххх to walk to the entrance), a snow whirlwind-cocoon (!) whirled around him, in which he reached the entrance !"

From this excerpt, what should be the outer parameters of a human body to create such effects on a freezing cold winter day?

Nope. It's magic.

Human body just does not have what it takes to create anything even just similar. Maybe if that walk took place in liquid methane or something like that...

Likely, the author wanted to hint some kind of protective field, but in any real environment it's a complete failure. In a cold day (cold, since it brings snow) wind is exactly the least thing anybody would wish around himself- so this 'protection' is actually some really sophisticated masochism, worst case: suicide.

So, just take it as magic.

There are many talents, but some context always helps, @SPL

Is this a paragraph you've written yourself? Or have you read it somewhere?

Either way, what genre of novel is it from? And do you require a realistic phenomena for this, or would some technically sounding handwaving suffice?

No, I didn't write it. And, I am actually interested in explanation in terms of a realistic phenomena. Let's just forget for a second about the human body. What sort of physical conditions might attract either dry snow from the surface, or if this were the case, condense it from the air?
Reverse engineering type of thing...

Yes, I was looking for some answers along these lines. But you don't this happening in winter time all the times. So what conditions would be involved? A human body is electrically neutral, nor it acts as a magnet under known conditions. But, the dust devil, I think is a good analogy.

Apparently, you don't get tornadoes in Antarctica because it is not warm and moist enough, so I'd expect the same constraints would limit smaller 'dust devils' occurring naturally in the conditions cited.

No, I didn't write it.

That's fine, but what genre was this from? You're asking about something that seems physically impossible based on text that seems entirely invented (I presume text, perhaps it's from a film or TV show). What level of proof that it can't happen would satisfy your curiosity, @SPL?
