A barogram is a graphical representation of the changes in atmospheric pressure over a period of time. It is a useful tool for meteorologists, pilots, and sailors who need to monitor changes in pressure to predict weather patterns and make important decisions.
Definitions
A barogram is a graph that shows the changes in atmospheric pressure over time. It is created by a barograph, which is a mechanical or electronic device that records changes in pressure.
