is it a cloud or a ufo ?

[space otter]

hey Z.. is there a cloud thread somewhere?..i remember a conversation about one.. but can't find it.....if it exists could you add this to it.?
thanks

The Freaky Cloud Phenomenon You Need to See

Alien invasion? Nope, it's just a big ol' gaping hole in the middle of a cloud. Everyone is going insane over the fallstreak hole cloud formation that appeared twice over the past two days in British Columbia, Canada. So what on earth is this extremely rare cloud formation? Also known as a hole punch cloud, canal cloud, or skypunch, a fallstreak hole is an expansive circular gap that appears on rare occasion.

The way they form is pretty fascinating. Meteorologist Eric Elwell explains it best: "Such holes are formed when the water temperature in the clouds is below freezing but the water has not frozen yet due to the lack of ice nucleation particles. When ice crystals do form it will set off a domino effect, due to the Bergeron process, causing the water droplets around the crystals to evaporate: this leaves a large, often circular, hole in the cloud."

Keep reading to check out all the mesmerizing photos British Columbians have been posting. The cloud looks like it's straight out of a science-fiction movie.

In my opinion is the result of a chemical chemtrails. I am not young, and clouds and skies I see now in Spain never saw. I am sailing Skipper and I've seen strange things, but the clouds were always clouds, no shit pulling now.

There are some mighty strange clouds that have shown up in the last few decades that were not around decades ago!?!?

But nobody wants to talk about that part of these strange new cloud formations, , , , , , , 

like rainbow effects in the clouds, , , , ,  ,

Just because you don't know about it it doesn't mean that's something new, like the example below.

In the airforce we used to call them inversion clouds. Extremely cold air rapidly dropping down fom a height of +31000 feet , pressing down clouds below it and slowly pushing them towards earth. In mid-level (15000 feet) the cold air warms up and the cold air mass and the mass of the clouds equalize so the clouds stop falling. At a height of 7500 feet there is no difference in temperature anymore and the clouds starts to float.

When warmer air goes upwards towards the clouds it pushes clouds away like a bubble of air in the water that moves upwards.

These events mostly happen during dawn or when the evening comes. Basically when the surface cools down, the sun still heats up certain parts of the earth and when cold air flows start to move down towards earth. During daytime the sun heats the surface and air is constantly moving upwards not giving cold air mass an opportunity to drop down.

Fallstreak Hole British Columbia

These are known as Fallstreak Clouds or Hole Punch Clouds

They are very common and recorded long before Chemtrail every appeared

Problem is back in those days people went about their lives rarely looking up at the sky. Today with all the UFO HAARP, chemtrail and geoengineering stuff and the interest in space and astronomy many people are looking up

Today everyone has a cell phone or camers, many have a telescope  So things that were rarely photographed back then are common today

But people who have never seen a rocket launch automatically scream "Alien UFO HAARP"  When you try to inject reason your the shill working for them

These don't last long so unless you have a handy camera they soon fade

A fallstreak hole, also known as a hole punch cloud, punch hole cloud, skypunch, canal cloud or cloud hole, is a large circular or elliptical gap that can appear in cirrocumulus or altocumulus clouds. Such holes are formed when the water temperature in the clouds is below freezing but the water has not frozen yet due to the lack of ice nucleation particles (see supercooled water). When ice crystals do form it will set off a domino effect, due to the Bergeron process, causing the water droplets around the crystals to evaporate: this leaves a large, often circular, hole in the cloud.[1]

It is believed that the introduction of large numbers of tiny ice crystals into the cloud layer sets off this domino effect of evaporation which creates the hole. The ice crystals can be formed by passing aircraft which often have a large reduction in pressure behind the wing- or propeller-tips. This cools the air very quickly, and can produce a ribbon of ice crystals trailing in the aircraft's wake. These ice crystals find themselves surrounded by droplets, grow quickly by the Bergeron process, causing the droplets to evaporate and creating a hole with brush-like streaks of ice crystals below it. The articles by Westbrook and Davies (2010)[2] and Heymsfield et al. (2010) [3] explain the process in more detail, and show some observations of their microphysics and dynamics. Such clouds are not unique to any one geographic area and have been photographed from many places.

Because of their rarity and unusual appearance, as well as very little exposure in media, fallstreak holes have been mistaken for or attributed to unidentified flying objects

If you google images for Hole Punch or Fallstreak clouds you will find hundreds of spectacular ones. The one in the OP is at sunset so you see the red and the shadows of the cloud

I meant a thread on here...

In my opinion is the result of a chemical chemtrails.

And on what did you base this opinion on?

I am not young, and clouds and skies I see now in Spain never saw. I am sailing Skipper and I've seen strange things, but the clouds were always clouds, no poop pulling now.

I too spent many years sailing as a kid and I saw plenty of weird clouds. But we had no photo equipment along on daily excursions

Fallstreak clouds are formed only under certain conditions

Yes cloud seeding COULD trigger one but cloud seeding is not chemtrails   And they rarely seed  cirrocumulus or altocumulus clouds  because there is not enough moisture in them to create rain

A New Understanding of Fallstreak Holes



Members and visitors might have enjoyed the fantastic collection of fallstreak-hole photographs displayed on our photo gallery. Also known as 'hole-punch clouds' these formations occur when part of a cloud of water droplets freezes into ice crystals. Scientists have known for some time that the effect occurs when the ice crystals grow large enough to fall below as a fallstreak. But what has always been unclear is quite why the freezing starts in one particular region of a cloud layer and how the hole grows in size, sometimes reaching 50km across an hour after the hole began. Now, research published in Science magazine has helped explain some of the mysteries of these beautiful fallstreak holes.

Formation and Spread of Aircraft-Induced Holes in Clouds

Hole-punch and canal clouds have been observed for more than 50 years, but the mechanisms of formation, development, duration, and thus the extent of their effect have largely been ignored. The holes have been associated with inadvertent seeding of clouds with ice particles generated by aircraft, produced through spontaneous freezing of cloud droplets in air cooled as it flows around aircraft propeller tips or over jet aircraft wings. Model simulations indicate that the growth of the ice particles can induce vertical motions with a duration of 1 hour or more, a process that expands the holes and canals in clouds. Global effects are minimal, but regionally near major airports, additional precipitation can be induced.

I meant a thread on here...

Yeah I got that

I was sure I did one but cannot find it LOL so it was likely just added into other threads

These keep popping up from time to time as UFO's  just like lenticular clouds and rocket trails

On FB it is so bad I don't even try to reply anymore As more and more people take pictures of things they don't understand and post them, there are more and more internet 'experts' willing to assure them it was HAARP Chemtrails from Alien Spacecraft

[zorgon]

With all the BS over chemtrails this and chemtrails that  people do ignore the fact that planes DO leave;

1) regular contrails - condensation from hot exhaust in cold air. Humans do the same when you breath out and see your breath as fog on a cold day. How long it 'persists' is dependant on how cold the air is I have seen the air turn to ice crystals in Winnipeg  Looks like millions of diamonds in the sunlight. Tried to find a photo but no luck. These ice crystals cause all sorts of halos and other odd effects like iridescent clouds from refraction through the ice like a prism or crystal chandelier does

2) Wingtip vortexes that normally invisible. But if the air is moist enough the disturbance will create trails. These vortexes are strong enough to rip the wings off a small plane if you get too close behind an airliner. It is one of the first things you learn in flight school. These can even come off the tips of the aileron on landing in wet climate (see below)

3) Condensation clouds behind the plane landing in wet weather or going in transonic speed (Mach One)

For these hole punch  here is the vortex effect created by airplanes    This one is just catching the top of a cloud  very appropriate for Valentine's Day



This one is the vortex created by a small plane (seen here using red smoke to show the effect



Here is an awesome one by a Coast Guard plane at sunset

[zorgon]

In light and thin clouds. it just punches a hole   This one is great as the plane flew along the layer of cloud instead of through it so instead of  a hole it left a wake like a boat does in water



BINGO!!! Here is one just created Took a while to find one



Here is another one that literally plowed a trench  but you would not see this from the ground because there are more heavy clouds below

Condensation cloud behind an airplane landing in wet climate

[zorgon]

In the two above you can see the wingtip vortex as well but here are better samples.  The wingtip and aileron tip vortexes are like mini tornadoes and expand as they move away  and sometimes do weird things like in these images

These are off the aileron tips  You can see the spirals



This one is a great one in silhouette. Clearly shows the rings of the spiral



And this one is crazy

[zorgon]

THIS ONE is spraying  We have a closeup of the nozzles



THIS ONE IS NOT a normal contrail or acrobatic smoke
