airmasses

/ˈɛrmæsɪz/ /ˈɛrmɑːsɪz/

Meanings

noun

A widespread body of air, the properties of which can be identified as: (a) having been established while that air was situated over a particular region of the Earth's surface (airmass source region) and (b) undergoing specific modifications while in transit away from the source region. An air mass is often defined as a widespread body of air that is approximately homogeneous in its horizontal extent, particularly with reference to temperature and moisture distribution; in addition, the vertical temperature and moisture variations are approximately the same over its horizontal extent.

Examples :

"Example Sentence: "The weather forecast explained that cold, dry airmasses from Canada were moving southward, causing a temperature drop and clear skies for the weekend." "

noun

The amount of air through which light from a celestial object passes, normalized to 1 for an object at zenith.

Examples :

"Astronomers calculate the effect of airmasses on star brightness, noting that a star near the horizon appears fainter due to the larger airmass than a star directly overhead. "
