1. occurring or existing at constant pressure
Usage: technical; used in physics, chemistry, and meteorology
2. relating to or denoting lines on a map connecting points of equal atmospheric pressure
Usage: meteorology

Examples

• An isobaric process in thermodynamics occurs when a gas expands or contracts while maintaining constant pressure.
• Weather forecasters use isobaric maps to identify high-pressure and low-pressure systems.
• The isobaric heating of air near the equator drives global wind patterns.
• In an isobaric expansion, the volume of a gas increases as temperature increases.
• Isobaric lines on a weather map help meteorologists predict storm movement.
