Usage: technical; meteorology
2. In chemistry, the existence of compounds with the same molecular weight but different structural arrangements.
Usage: technical; chemistry

Examples

• The meteorologist studied isobarism across different regions to predict weather patterns.
• Isobarism in the upper atmosphere affects wind circulation and storm development.
• The concept of isobarism helps explain why certain areas experience similar pressure conditions simultaneously.
