A ceilometer is a specialized meteorological instrument used to determine the height of a cloud base or the “ceiling.” It uses a laser or other light source to measure the time it takes for a pulse to reflect off the ...

The Coriolis force is a result of the Earth’s rotation on its axis. It causes moving air—winds—to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This force is essential for the formation ...
A temperature inversion occurs when the standard rule of the troposphere—cooling with height—is reversed. In this scenario, a layer of warm air sits above a layer of cooler air near the surface. This creates a stable “lid” that traps pollutants, ...
Albedo refers to the reflectivity of the Earth’s surface and atmosphere. Cloud cover is the primary driver of this effect, as the white tops of clouds reflect a significant portion of incoming solar radiation back into space. By preventing this ...
Water vapor is the most variable gas, ranging from nearly 0% in cold, arid deserts to 4% in humid tropical regions. Unlike “permanent” gases like nitrogen and oxygen, which remain in constant proportions, water vapor concentrations shift rapidly based on ...
