A fish shaped cloud, more accurately described, is not a single cloud that looks like a fish but rather a pattern of clouds that resemble fish scales.
Understanding "Mackerel Sky"
This pattern is commonly known as a mackerel sky. Here's what it entails:
- Description: A mackerel sky is characterized by rows of cirrocumulus or altocumulus clouds.
- Appearance: These clouds display an undulating, rippling pattern. This pattern is reminiscent of the scales of a fish.
- Cause: This distinctive look is due to high-altitude atmospheric waves.
Cloud Types Involved
The clouds primarily associated with a "fish shaped" cloud pattern are:
- Cirrocumulus: These are high-altitude clouds, composed of ice crystals. They appear as small patches or ripples.
- Altocumulus: These are mid-altitude clouds, made up of water droplets and sometimes ice crystals. They often appear as grayish-white patches or layers.
Why the Term "Mackerel Sky?"
The term “mackerel sky” comes from the cloud pattern's visual similarity to the markings on the back of a mackerel fish. It's a good example of how we use familiar comparisons to understand natural phenomena.
