Latest Cirrus cloud Stories
A new NASA field campaign will begin flights over the Arctic this summer to study the effect of sea ice retreat on Arctic climate.
NASA's Global Hawk No. 872 completed a 17.5-hour science flight Feb. 14, it's first for the 2014 Airborne Tropical Tropopause Experiment (ATTREX) mission.
A new study reveals how pollution causes thunderstorms to leave behind larger, deeper, longer lasting clouds.
The clouds on Mars, at first glance, might be easily mistaken for those on Earth. NASA's Opportunity rover returned images of the Martian sky with gauzy, high-altitude wisps that are similar to our cirrus clouds.
Scientists studying the Aral Sea's changing ecology and retreating shoreline have looked to Landsat -- and a new feature of the Landsat Data Continuity Mission will help ensure they get a clear, cloud-free view.
At any given time, nearly one-third of the planet is covered by cirrus clouds – the thin wisps of vapor that trail across the sky – which coalesce in the upper layers of the troposphere, as much as 10 miles or higher above the surface of the Earth.
Have you ever looked up in the sky and wondered what all those different types of clouds actually are? Well to be exact there is a cloud for every type of weather event.
NASA's Solar Dynamics Observatory (SDO), best known for cutting-edge images of the sun, has made a discovery right here on Earth.
Clouds play a major role in the climate-change equation, but they are the least-understood variable in the sky, observes a Texas A&M University geoscientist, who says mid-level clouds are especially understudied.
When Patrick Minnis saw video of the "mystery" contrail Nov 9 that looked like a missile launch near Catalina Island off Los Angeles, he figured it the way most people did.
The above map looks at what is known as ceilings. The definition of ceilings is the first broken or overcast layer of cloud cover in the atmosphere. For it to be considered a ceiling the clouds need to cover more than half of the sky. If we look at the red circled area we see the numbers of 1 and 2. This tells us that there is a ceiling at 1,000-2,000ft which are in the level of low clouds such as cumulus or stratus. The second is the black circle found in the Dakota’s. Here we are...
If you look in the photo above you can see the line of Cumulus clouds that appear in the background. These clouds were created by daytime heating and also an unstable atmosphere. The moisture for these clouds was rising from the Pacific Ocean. The darker cloud is the stronger of the cumulus clouds meaning that the majority of the moisture is being absorbed by that cloud. The clouds around this one are also starting to get more moisture from the ocean to build. Above the cumulus clouds you...
Cirrus clouds are thin wisplike strands, sometimes accompanied by patches. Their shape and arrangement lead to their common name of "mare's tail". These clouds can be so extensive that they are virtually identical to one another and hard to tell apart. Sometimes high altitude convection produces another form of cirrus called cirrocumulus. Many cirrus clouds produce hair-like filaments made of heavy ice crystals that precipitate from them. This precipitation often indicates the difference in...
Cirrocumulus clouds are high-altitude clouds that mainly occur between 16,000 and 40,000 feet. Like most cumulus clouds, these clouds indicate a vertical and upward transference of atmospheric conditions. Unlike other cirrus clouds, cirrocumulus composition includes super-cooled liquid water droplets. Ice crystals are also present, and usually, the ice crystals cause the droplets in the cloud to freeze rapidly, transforming the cirrocumulus into cirrostratus. This process can also produce ice...
- In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
