Like cream mixing in a cup of coffee, atmospheric winds swirl clouds into eye appealing patterns determined by mixing boundaries and turbulence. Note also the subtle iridescence at the bottom edge of the cloud created by diffraction of light through the cloud droplets.

Thanks for taking time to fave, comment and look at my work. I really appreciate.

It looked ominous, but we got less than a 1/10th of an inch of rain out of it.

The start of our new weather serie.

Cumulus Humilis clouds

Cumulus clouds mostly form as a result of localized pockets of warm air rising.

Cumulus humilis is the smallest form of cumulus clouds and results from relatively weak convection (humilis means humble in Latin). This produces clouds that generally have flat bases and small, rounded tops. Technically, a cumulus cloud is considered to be a humilis formation if it is wider than it is tall, as estimated by an observer on the ground. The height of these type of clouds is about 500 tot 1000 meter or 2000 to 3500 feet. It's unusual that rain falls out of these type of clouds.

Attention friends, we've got ourselves another one who'se taking our pictures, with a link to 500px, but not mentioning where it came from: www.flickr.com/photos/michaelhaupt/14632815455/in/photoli...:

On the Hohenbol above the clouds at this morning

Auf dem Hohenbol über den Wolken an diesen Morgen

Almost Spring Sun.

The summer storms we call "monsoons" arise from mixing wet air from the Gulf of Mexico with heat rising from the desert have finally started getting into gear, bringing rain and cooler temperatures to Arizona.

I spotted the bright white vertical column of the thunderhead as I was driving east on AZ highway 260 from Camp Verde to the top of the rim. I was looking for an angle to get the photo, and remembered this bumpy side road off the highway. But there was still a hill in the way, so the dog and I started stomping up the rise, trying not to think about the likelihood of rattlesnakes. I did not top the rise, but the view opened up to give this shot.

That is what they looked like to me. The clouds were moving really fast that morning ... this was only a 5 second exposure.

or so they tell us--for a bit at least. It's been one blast after another for months, it seems!

Clouds come floating into my life, to add color to my sunset sky, after darkness time. *Pura*
