🔍 Key Concepts

• Isobars show lines of equal pressure and generally bend or curve near pressure centers (highs and lows). • A front is a boundary between air masses, and pressure typically changes across it in a predictable way. • Think about how the pressure pattern must look around a low-pressure center as it connects across a frontal boundary.

💭 Think About

• Visualize a low-pressure system with a front extending from it. How do the isobars wrap around that low, and what happens where they cross the front? • If an isobar is crossing from higher pressure into lower pressure across a front, in which direction would the ‘kink’ have to point to keep pressure values consistent on that line? • Compare how an isobar behaves at a cold front versus a warm front—does the direction of the kink depend on the type of front or just on the pressure pattern?

✅ Before You Answer

• Confirm that an isobar must always connect points of exactly the same pressure, even where it crosses a front. • Check whether the direction of the kink should logically point towards lower pressure or higher pressure, given how isobars wrap around systems. • Verify whether any correct rule you’ve learned applies only to warm fronts or to all fronts, and eliminate answers that are too specific without support.
