It refers to the atmospheric pressure which, in this case, is measured in inches of mercury on a mercury barometer

The two most common units used for air pressure in weather reports are: Inches of Mercury and Millibars.
The two units of air pressure commonly used in weather reports are millibars (mb) and inches of mercury (inHg).

I just found out after I had retaken my test, it is millibars.
Barometers and weather maps typically display atmospheric pressure in millibars (mb) or hectopascals (hPa), which are equivalent units. In some regions, especially in the United States, atmospheric pressure may also be expressed in inches of mercury (inHg). These units help meteorologists analyze and predict weather patterns based on pressure changes.
1,2,3,4,5,6,7,8,9, that are the units ( i think) well bye!
American units of air pressure include pounds per square inch (psi) and inches of mercury (inHg). These units are commonly used in weather reports and aviation to measure atmospheric pressure.
In the United States, the two units of air pressure commonly used in weather reports are inches of mercury (inHg) and millibars (mb). Inches of mercury is often used in local weather forecasts and reports, while millibars are typically used in meteorological contexts, including weather maps and scientific discussions. Both units are essential for understanding atmospheric pressure and its effects on weather patterns.
it means high pressure
It means low pressure and low pressure means that wherever the L is there will be stormy weather.
