In the summer, the much warmer air mass expands like a dome and causes the troposphere to reach a height of 11 miles above the surface. This is why clouds tend to grow bigger and taller in the summer ...

There are more ways than we knew for the stratospheric polar vortex to get disrupted, shooting cold air southwards across ...

Speeding around the Earth at 28,000 km/h, NASA astronaut Nichole Ayers captured an incredible view of a phenomenon known as a ...

This extraordinary event is known as a sprite — or “farfadet” in French — one of the rarest forms of Transient Luminous ...

Climate change left its signature on the atmosphere early in the industrial revolution, reveals a thought experiment ...

If scientists of the 19th century could have used modern tools to study the atmosphere, they might have noticed the early warning signs of a major shift: human activities, like burning coal and wood, ...

Explore the layers of the atmosphere depicted to scale, including the Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere. Discover what occurs in each layer. This video is available ...

The stratosphere is the second layer of the atmosphere from the ground, at about 20 to 50 kilometers high. Below, in the troposphere, temperatures decrease with height, but in the stratosphere, it ...

The polar vortex is a circular flow in the stratosphere, which extends from the top of the troposphere to altitudes of about 30 miles. This circular flow forms every fall, and vanishes in spring.

The troposphere is the lowest layer of the atmosphere, where all weather occurs, as well as where we live. This year, the vortex’s behavior was atypical in this atmospheric layer.

Japanese scientists have created the first-ever long-term dataset about Earth's entire atmosphere, stretching all the way to space.

The envelope of gas surrounding the Earth changes from the ground up. Five distinct layers have been identified, the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
