A Time lapse of a cloud formation on top of Mt rainier.The cap cloud (the official name is "lenticular cloud") is formed when warm, moist air runs into the surface of Mt. Rainier. The mountain's topography forces the air upward, which cools and condenses the air -- turning it into a cloud.

As the air sinks back on the other side of the mountain, it dries out and the cloud dissipates. That's why it just hangs over the summit area.

(Although it looks like it is "hanging" over the mountain, air is continually flowing over the summit.)

Locals have used the cap cloud as a sign that rainy weather is on the way, as it usually occurs with southwesterly flow in the upper atmosphere -- a usual precedent to rainy weather. However, that's not always the case. please watch in high resolution. It looks like a cap. If you look closely you can see an almost perfect cone in the middle of the clouds over the top of the mountain. It took about 1 & 1/2 hours to get this time lapse.Lenticular clouds, stationary lens-shaped clouds, aligned perpendicular, altocumulus, lenticularis stratocumulus lenticular,cirrocumulus (UFOs).clouds chemtrails mountains beiber weather number mt sky form lenticular apod cold event skies living air justin beiber anti capture rainier

  • That's some great position you have -- where were you? This is really fun to watch. I think I may have been shooting the same event, but further away.

  • @88edwardo I have a secret location & I cannot reveal. Neighbors might not let me in again if people started showing up. LOL (only a year late in my reply)

  • what music is this? it is very nice

  • @Mattecka----- Alexander Perls - Storm (Short Edit) Download This Song: iTunes AmazonMP3 eMusic

  • I'm surprised you didn't capture any chemtrails. Everyone must see the documentary "Don't talk about the weather". Search YouTube for it.

  • I wish I had. This time lapse took almost 2 hours to make. I did not realize about the Chemtrails until I viewed the finished video. It was so slow I did not know it was happening. I'll get them next time though!

see all

  • Wow -- this is the best capture of that lenticular day that I've seen. Where were you? I'm always on the lookout via webcams for this type of event -- kind of few and far between lately around here.

  • DAMN I HATE THIS SONG!!

  • I'm thinking some Justin Beiber music would go perfect with this chemtrail formation.

  • wowo excelent !

  • @JayRebel I've studied the sky and atmosphere for over a year. Start with the NASA appleman chart, then take your eyes and camera to the skies like me. I am convinced there is some secret geo-engineering or something else going on. Peace

  • @TrutherD1 Why do all straight, thin clouds have to be "chemtrails"? Basic science lesson - High altitudes are cold, exhaust from airplanes is very hot. When hot air meets cold air.....well if you haven't already figured it out, you need to go back to school. There ere no "chemtrails" in this video because an airplane didn't fly through the shot. Am I the only one that sees the logic in this?

  • Very nice video. We are hosting a World Anti Chemtrail Day on 20-11-2010, everyone is welcome. Please check out the page, and share this information ASAP.
