Altocumulus clouds act as a visual cue for a changing weather pattern. These are the types of clouds that appear ahead of a strong cold front and are a common sight. They indicate the presence of ...

The main part of this cloud is made of an altocumulus cloud. These midlevel clouds form between 7,000 to 23,000 feet and develop in a similar way as cumulus clouds or thunderstorms.

Altocumulus clouds are "mid-level clouds composed primarily of water droplets," according to the National Oceanic and Atmospheric Administration (NOAA). These groups of fleecy clouds share some ...

A fallstreak hole occurs when a layer of mid-level clouds, like altocumulus clouds, gets disturbed by either warmer pockets of air beneath the cloud, or an object punching through them, like an ...

Thu., Feb. 16, 2023 National Weather Service forecaster Jon Fox captured an unusual altocumulus cloud formation in 2015 to the east of Spokane.

Altocumulus clouds are composed of water droplets that, in cooler environments, become super cooled. That is, they remain in a liquid state at temperatures below the freezing point of water.

According to WRAL meteorologist Aimee Wilmoth, these clouds that resemble jellyfish are patchy altocumulus clouds with virga (rain that evaporates before it reaches the ground) at the bottom of ...

A NASA satellite has captured a rare, stunning image of New Zealand’s Taieri Pet, a peculiar lenticular cloud that consistently forms over the Strath-Taieri region of the country’s South Island.

It usually happens in altocumulus, cirrocumulus, lenticular and cirrus clouds. Iridescent clouds happen because of diffraction – a phenomenon that occurs when small water droplets or small ice ...

The formation is called a fallstreak hole, or a hole punch cloud. It's a circular or elliptical gap that can appear in a deck of cirrocumulus or altocumulus clouds.

Over the Florida Keys, these celestial wonders were noticed by NASA and fishermen alike. The sky formations are known as "cavum clouds" or "fallstreak holes." Here we explore unique facts about ...
