Which of the following units is used by meteorologists to measure air pressure? View Available Hint(s) \( \begin{array}{l}\text { pounds per square inch } \\ \text { grams per cubic centimeter } \\ \text { millimeters } \\ \text { millibars } \\ \text { milliliters }\end{array} \)

Meteorologists primarily use millibars to measure air pressure, which is a unit that quantifies the weight of the air above a given point. One standard atmosphere is equivalent to 1013.25 millibars, making it a crucial aspect of weather forecasting and understanding atmospheric conditions. In practical terms, air pressure readings in millibars help meteorologists predict weather patterns. For example, low-pressure systems often indicate stormy weather, while high-pressure systems are associated with clear skies. Understanding these variations can significantly improve our ability to plan outdoor activities or prepare for unexpected weather changes!
