isotherms

Lines of equal warmth

Isotherms are lines on a map or chart connecting points of equal temperature.

Weather maps use isotherms to show temperature patterns across regions: The isotherms dipped southward, indicating a cold front.

In physics and chemistry, an isotherm describes a process occurring at constant temperature, as in graphs showing gas behavior under pressure changes.
