Barometric Pressure Readings
Barometric pressure refers to the pressure exerted by the atmosphere
at a given altitude. It may be expressed in either millibars
(mb)/hectopascals (hPa), or inches of mercury (inHg). A rising or falling
barometric pressure reading indicates the likelihood of fair or poor
weather conditions.
- A high or rising barometric pressure indicates fair weather conditions.
- A low or falling barometric pressure indicates poor weather conditions.
An arrow icon by the the barometric pres-
sure readings indicates if pressure is rising,
falling, or steady.
