Mammatus Clouds - Very Rare And Cool!

Thu Jul 20, 2006 4:43 pm

I am fascinated by Mammatus Clouds. I have only seen them twice, but never in California where I live. Have you ever seen these clouds? Have you taken any pics?

See them almost daily during summer thunderstorm season. Really cool when the sun is about to set it lights them up and they look very eerie.

Yes like everyone else says...these clouds are amazing and I honestly never knew they existed!!! The first picture does look like a cartoon like VHVXB says! That was the first thing to cross my mind!

Thanks for posting the pictures!

Excellent pictures, especially with the sunset red. I've only ever seen them once, while going through Nebraska, though they weren't as "detailed" as those pictured.

I love clouds, my friends laugh at me when I show them pictures from my travels, I always take a LOT of pictures of clouds from the plane.

I think I might get lucky tonight on my flight BRU-WAW, it's clouded now!

I used to see them a lot during bad thunderstorms in NC....

They also appear here in Montana about 4 times a year...

Mammatus clouds tend to form more often during warm months. In the United States, they tend to occur more often over the midwest and eastern portions of the country, though they can and do occur more infrequently over the west and southwest. ~Wikipedia

Yes, over Grand Forks, ND in September, 2005. Then had a wicked thunderstorm roll through. Didn't get any pictures tho. Wish I had.

I have seen Mammatus Clouds only a couple times and never really as developed as in these pictures. If you see Mammatus Clouds, hang on to your ass, its a good sign that Tornadic activity can and usually will follow.

Excellent pictures, all of them. We see them pretty frequently in West Texas because the air is clear, the ground is flat and you can the the underside of the rear portion of the anvil from a long distance away.

I'll have to partially disagree with you, KROC. Mammatus are not necessarily indicative of a tornadic thunderstorm. The two features are independent of each other and either or both can be present in a given supercell thunderstorm. In the structure of a thunderstorm, a funnel cloud will usually form from a wall cloud at the bottom of the storm. Mammatus are very high in the storm, under the rear portion of the anvil at the top of the storm:

Source: http://www.theweatherprediction.com/severe/structure/



"C. Mammatus- Mammatus are pouched shaped clouds that protrude downward from the thunderstorm's anvil. They form as negatively buoyant moisture laden air sinks. The cloud remains visible until the air sinks enough that the relative humidity falls below 100%. The portion that has a relative humidity of 100% remains visible. Theories to how they form include: 1) turbulent eddies mixing down moisture, 2) evaporational cooling with surrounding air causes pockets of sinking air, 3) Pockets of precipitation falling out of the anvil that produce virga. Mammatus tend to be most prominent in extremely severe storms but can occur when storms are not severe also.

F. Wall Cloud- The wall cloud is located in the updraft region of a supercell. Rising air cools and condenses out moisture once it is saturated. Due to the rapidly rising air and the verticality of the rising air, the cloud base is close to the ground within the wall cloud. The wall cloud will often be witnessed as rotating since directional wind shear acts on the updraft as it rises. Tornadoes can occur under the wall cloud."

I've seen Mammatus clouds in Melbourne - I even remember the date because it was the day of a Australian Severe Weather Associating AGM, August 13 2005 - It was winter here but it wasn't extreamly cold, It would have been about 16c'ish - There was no storms that day or even rain, It was quite average but that said The clouds weren't as pronounced... I thought they were quite amazing looking, so did everyone else I was with though too.

I must say America gets some amazing activity compared to Australia... I'd love to go storm chasing there one day

That reminds me - A few of the people I was with were talking about 'naders and those clouds

supposedly, Outside of the USA, Australia has the highest occurances of Tornados, with my state being the one that has them all, apparently we have more rotation here or something, Mind you we only get small ones when we do... or as the Media has taken to calling them... "Mini-Tornados"

I've seen them once, back in the early 90's when I was in high school. It wasn't the day we learned about them in Earth Science class, but probably the same week. I was on a golf course after school, looked up and saw them with a storm coming in. We sat out the storm in a flimsy wooden lightning shelter on the course, but learned afterwards that they were indeed associated with a tornado which hit about a mile down the road from where I was. A golf course is not a good place to be in a tornado and I consider myself quite lucky. We don't get many tornados in upstate NY and I haven't seen them since.

I have seen Mamattus clouds quite a bit and they still amaze me to this day. Although Mamattus clouds form often on supercells that can spawn tornados they are likley to tell you that strong straight line winds and large hail are the "almost certain" Threat. As a side note Microbursts and powerful downdrafts often form in these storms.

They look like soap suds and we're underneath the water. If tornadoes are almost certain to follow, I'll just stay with the pics and not the real things.

I am amazed that none of you guys have giggled over the word "mammatus" yet. The cloud type is described as having "udder-like protrubances"...and doesn't "mammatus" sound related to "mammary"? Coincidence? I think not.  Smile

That said, I've seen these a couple of times around Seattle but not anywhere near that dramatic. We did get them in Thunder Bay when we had storms go through.
But that was when I ruled the world
