Isobars are lines drawn on a weather map that connect geographic locations with the same atmospheric pressure at a given time. By looking at the pattern of isobars, meteorologists can identify areas of high and low pressure. The spacing between ...

In the Northern Hemisphere, wind circulates counter-clockwise around a low-pressure center. This occurs because air naturally moves toward the low-pressure “void,” but the Coriolis force deflects that movement to the right. The resulting balance between the pressure gradient and the ...
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, ...
