Ice crystals in Earth's atmosphere sometimes align just right to create various striking visual effects, from a halo around ...

A new study shows that natural dust particles swirling in from faraway deserts can trigger freezing of clouds in Earth's Northern Hemisphere. This subtle mechanism influences how much sunlight clouds ...

By producing fewer and larger ice crystals, clouds that undergo heterogenous nucleation end up reflecting less solar radiation, but they also allow more radiation from Earth to escape into space.

In clouds in the mid-to upper atmosphere where temperatures are between 32 and minus 36 F (0 to minus 38 C), ice crystals normally form around mineral dust particles from dry soils or biological ...

In the decades since CLAW, researchers like Thornton have observed the ocean eject biological particles into the atmosphere directly. These aerosols drift upward and collect ice crystals. Waves ...

Rare clouds that form in summer high up in the Earth's atmosphere have been seen from parts of Scotland.BBC Weather Watchers who were up from between about 02:00 to 06:00 on Tuesday spotted the ...

MIKE MOSS SAYS: Bill, Rings around the moon can be caused by ice crystals or by small water droplets in clouds that are shallow enough to allow the moon to be seen behind them, and the ring size ...

What color is moonlight typically, and what other colors can moonlight look like from our perspective on Earth?

While flying over West Texas this past weekend, a man captured a rarely seen weather phenomenon lighting up the sky. Ken Skillern was at the place at the right time when he used his iPhone 14 Pro ...

First, there must be a nearly clear night sky. However, in addition ice crystals are needed to be present high in the atmosphere. This is provided by cirrus clouds passing between you and the moon.

The extent of Antarctic sea ice dropped precipitously in 2023. Analysis shows that this decline has increased the transfer of ocean heat to the atmosphere — in turn affecting ocean circulation ...
