Polar explorers of the 30th Antarctic expedition managed to see a beautiful and rare phenomenon - mother-of-pearl clouds.

In the summer, the much warmer air mass expands like a dome and causes the troposphere to reach a height of 11 miles above ...

Most of Earth’s clouds form in the lowest level of the atmosphere, known as the troposphere, at altitudes between roughly 1-11.5 miles above the surface.

Thunderstorms can be characterized by their classic anvil-shaped tops, which are where the air hits a strong, stable layer of ...

Clouds form when the water vapor reaches an altitude where the combination of temperature and air pressure is right for condensation. The methane clouds in Titan’s troposphere form in a similar way.
