🔍 Key Concepts

• Cyclone motion relative to isobars on a surface weather map • The difference between movement parallel vs. perpendicular to isobars • What the warm sector of a cyclone is and where it lies on the fronts

💭 Think About

• On a surface chart, how do winds generally flow in relation to isobars around low pressure systems in mid-latitudes? • In the warm sector of a cyclone (between the warm front and cold front), how is the pressure pattern arranged, and how does that guide the system’s overall track? • Which answer choices talk about motion relative to isobars, and which talk about motion relative to fronts? Which is more fundamental for cyclone movement?

✅ Before You Answer

• Identify which options refer to isobars and which refer to front lines • Recall that large-scale storm systems tend to follow the pressure pattern aloft and at the surface, not necessarily the orientation of a single front • Make sure you know exactly where the warm sector is located on a classical mid-latitude cyclone diagram before choosing your answer
