First, as I mentioned, is the troposphere. This is the lowest layer of the atmosphere, where all weather occurs. It begins at the ground, and extends upward to about 6.2 miles above earth’s surface.

IN his letter in NATURE of February 27 Mr. Dines asks why the adiabatic conditions which prevail in the lower part of our atmosphere should suddenly cease at a height of about 40,000 feet. The ...

Space Astronomers uncover the topsy-turvy atmosphere of a distant planet. The gas giant WASP-121b, also known as Tylos, has an atmospheric structure unlike any we have ever seen, and the fastest ...

The Earth’s atmosphere has a number of layers. The region we know best, because it is where our weather happens, is the troposphere. This dense blanket of air 5 to 9 miles thick contains 80 ...

Researchers have created a dataset of the whole atmosphere, enabling new research to be conducted on previously difficult-to-study regions. Using a new data-assimilation system called JAGUAR-DAS ...

Upper atmospheric cooling is the phenomenon in which, "while the blanket of air close to the Earth's surface is warming, most of the atmosphere above is becoming dramatically colder," as defined ...

Extremely clean air on the ground, warm air intrusions and sulphate aerosol at high altitudes -- a research project has gained new insights into clouds in Antarctica.

Every year, hailstorms cause billions in damage to homes, businesses, and crops, yet how these ice balls of destruction form in the upper troposphere has remained somewhat of a mystery. The ...
