Wow,

Those are amazing. Nice find!

[ThE BrIcK]

That's cool!

I like the one that looks like a Nuclear Bomb Explosion.

[Plixity]

WOW! My brother wants me to make a sig from a couple of those for him XD (different forum =\).

Nice find!

I agree, I like the nuclear explosion cloud that I'm assuming was not formed by a Nuclear explosion. Good find Railziel

i have to say that this is AMASING
i am very passionate about the sky and all those clouds are amazing!

nice finding!

Wow, those are some pretty amazing pictures! I love taking pictures of clouds, they are always really interesting.

Personally, my favorite was the one with the full moon in it.

nice find!

3179 was taken from a plane and would have been a very very bumpy ride going through them. 3153 is not really clouds, but "up-slope fog" which is one of the few obscuration weather phenomena requiring wind to keep it present (usually wind removes obscurations - clouds, fire smoke, haze). 3140, 3051 are lenticular clouds typically seen only over mountains and is suggestive of severe turbulence an winds in excess of 50knot which is excessive at that altitude. 3109 is going to be a really ugly storm and 3128 is just cool. I saved some as desktops.

3182 - One bad cumulonimbus anvil! If I saw one of those heading for the base Back when I was in the Air Force I would have issued a Severe Thunderstorm Warning STAT! That beast likely had 40KT winds and 1 inch hail at the least.

3181 - "hat" feature is indicative of either an incredibly strong updraft or very strong winds in the upper levels of the atmosphere. Likely an unstable environment ideal for T-Storms

3183 and 3186 - altocumulus standing lenticular clouds. Actually it is not only indicative of severe turbulence, but also of the category EXTREME turbulence. That is the highest and most dangerous level of turbulence where control of the aircraft is all but lost.

2050 - Another sign of turbulence. These "cap clouds" are caused by strong winds hitting perpendicular to the mountain. The winds rapidly flow up over it and then back down. This causes the up and down motion to continue for sometimes hundreds of miles downstream. altocumulus standing lenticular is frequently associated with this phenomena.

2119 - Avoid at all costs! Roll clouds occur frequently with lenticulars, normally below them. These clouds are formed by strong winds literally flowing in a circle so tightly that you could almost call it a sideways tornado in midair. Extreme turbulence and sure death to any pilots!

Ah yes... the weather geek in me loved some of that. Former U.S. Air Force Meteorologist Craftsman is what I am. Anyone with any particular weather questions I would be more than happy to answer for you.

Good to know, would not have recognized that one. I only fly the little stuff though so I imagine the weather/turbulence within miles of that would be bad enough to keep me away.

Awesome
