Hourly weather observations that include sea-level pressure readings are plotted or printed on weather maps that meteorologists can analyze. Isobars are drawn by connecting points having equal ...

Hourly weather observations that include a sea-level pressure reading are plotted or printed on weather maps that meteorologists or computers can analyze. The isobars are drawn by connecting lines of ...
