Hello, my name is Evelyn. I am a weather addict.
Maybe some of you readers are sane, sober people reading the almanac for tips on growing your gardens. But if you are hooked on weather, particularly if you love clouds, l have the good stuff here.
One of the enjoyable pastimes of weather addiction is cloud watching. I live in New Mexico, where the sky is such a deep blue that native tradition believed turquoise was small pieces of fallen sky. Part of the joy of being outside is just to gaze into the endless blue and watch the clouds form, shift and dissolve.
Scientists explain that warm air collides with cooler air, causing the moisture in the air to condense from gas to droplets or frozen particles. Science aside, clouds form weird and wonderful shapes and images.
Here are three relatively rare clouds types I have seen here in New Mexico. Have you seen them?
Jellyfish clouds or virga

These clouds are common in the desert, but rare elsewhere. Those jellyfish tendrils are rain that can’t reach the ground. They occur when the ground heats the air so it evaporates the falling rain.

Anyone who has milked a cow knows how these clouds got their name. They are sagging pouches that form on the base of larger clouds, like the anvil clouds of thunderstorms (where they sometimes indicate a potential tornado.) There are many theories why these puffs of moisture form under the clouds but so far there are no real answers. While an individual lobe usually lasts only 10 minutes, the boiling cluster can linger for hours. It’s an incredible sight.

Named for Lord Kelvin and Hermann von Helmholtz, these weird clouds appear when two layers of air are traveling at different speeds and the faster top layer ripples the moisture of the lower air mass. They are rare and as a sign of unstable air, seldom last longer than 10 to 15 minutes. In the West, they sometimes appear when cool air races up one side of a mountain and glides over the air on the other side.
Have you seen these beauties? Better yet, do you have pictures of any weird or wonderful clouds to share? Enjoy our cloud ecard gallery and upload your own picture.
