An instrument for measuring atmospheric pressure.

A bomb cyclone is a large mid-latitude storm that forms when a storm’s central pressure drops (i.e. “bombs out”), resulting...

A drainage wind that flows downhill due to gravity, often associated with cold air descending from elevated regions.

The decrease in temperature with height in an adiabatically rising air parcel (lapse rate). For dry air, this value is 1...

Cloud or rain droplets containing pollutants, such as oxides of sulfur and nitrogen, to make them acidic.

Jet streams are strong, fast-flowing air currents in the upper levels of the atmosphere. They form when warm air masses meet...

A line on a weather map connecting points of equal atmospheric pressure, used to identify high and low-pressure systems.

The term 'cloudy' refers to weather conditions characterized by a significant amount of cloud cover in the sky. This may...

A periodic cooling of sea surface temperatures in the central and eastern Pacific Ocean, often leading to altered global...
