Imagine a cloud that always shows up in the same place, like a pet waiting for you at home. This unique cloud, known as the Taieri Pet, does just that! It's a seven-mile-long, sausage-shaped lenticular cloud that hangs out above Otago, a region in New Zealand's South Island. Locals have been seeing it since 1896, giving it the nickname "Taieri Pet" because it feels like their very own cloud.

In September 2024, NASA's Landsat 8 satellite caught a stunning image of this cloud. Lenticular clouds like the Taieri Pet are interesting because they form in the lowest part of Earth's atmosphere, the troposphere, and look like flying saucers or UFOs. They typically show up over mountain tops or ridges, and in this case, the Rock and Pillar Range in Otago is responsible. When strong winds from the northwest hit these mountains, they're forced to go up and over, creating a wave. As the humid air rises and falls, it forms the stationary cloud.

But this stillness can be deceiving. John Law, a meteorologist at New Zealand’s MetService, explains that the Taieri Pet is a sign of strong winds high in the atmosphere. The cloud's smooth, stacked-pancake look is due to these powerful winds carving it. Even though it appears motionless, it's actually shaped by the wind blowing through it.

These clouds can be tricky for pilots. Flying through a lenticular cloud like the Taieri Pet can cause severe turbulence. So, while it might look like a friendly cloud pet, it's important for pilots to give it some space.
