North Downs looking south towards Reigate, Sunday 27th January. Lovely sunny day (for once!!) though, bloomin'eck it was windy!



And yes, for those out there, I set the camera to sunset, to add a bit of oomph to the clouds. Darkens stuff you'd rather keep light, but there we are … a compromise.
Certainly never seen cycling south of Sussex

Some good old fashioned Scottish clouds.

Contrast turned up on this one to capture the detail in the clouds (Samsung phone)


Same walk..same soaking

Aren't sheep just clouds with legs anyway?

No, they are boulders that move of their own accord and eat grass.

Only because he has some rather spectacular cumulo-granite in his piccy. The fluffy stuff is pretty ordinary. Ish.

Tcha! Really?

I see:

Cumulus Fractus
Virga
Cumulonimbus
Stratocumulus

and a precipitation plume that would have your average pilot thinking "microburst" and asking ATC for some leeway  ;) ;D

I see all of that - well, most of it. This is winter in Turkey. Isolated cold-sector CBs at this latitude at this time of year are relatively benign. Yes, there's virga, but that doesn't suggest microburst in this environment. Might be a bit bumpy, but icing would be far more dangerous than air movement in this cloud!

I may as well do the whole thing, then.

Here's the same cloud a little earlier:

Then getting a bit closer:

I didn't get wet, but it was bloody cold.

Was it windy approaching the mountains? A tailwind, perhaps? If so, this would be an orographically-generated CB. No matter; a cu-nim building in a fairly short time, even in winter, will have quite strong up- and downdrafts. The downdrafts produce the coldness you experienced, along with the precipitation plumes (snow, in this case) Chris referenced. Actually, your second picture in the sequence above tells me far more than the foreboding and atmospheric last image.

My diary that day was about four lines - my hands were really numb. But I mentioned a tailwind until I was under the cloud, when it became what felt like a northerly. I was heading east, just about.

Yeah, makes sense. There may have been more than one cell in that cloud, but each cell's central updraft is surrounded by a ring of downdraft which spreads radially from the cell on reaching the ground. It meets and combines with the pressure-gradient wind, and may even overcome it - giving exactly the effect you describe. At some later point you'd have had a stronger - and colder - tailwind, assuming you kept going in the same direction.
