Barometric Pressure
Barometric pressure, also known as atmospheric pressure, is the force exerted by the weight of the Earth's atmosphere on a unit area of surface. In maritime context, barometric pressure is an important indicator of weather patterns and changes. It is measured using a barometer and is expressed in units of pressure such as millibars (mb) or inches of mercury (inHg). Changes in barometric pressure can indicate the approach of a storm or other weather system, and can also affect the behavior of the ocean, including the height and frequency of waves. Understanding barometric pressure is crucial for safe navigation and weather forecasting at sea.
