🔍 Key Concepts

• Tropical cyclone life cycle – how hurricanes can change type as they move away from warm water • Difference between tropical and mid-latitude (frontal) weather systems • Typical pressure patterns: low-pressure vs high-pressure systems

💭 Think About

• Which of these choices still describes a tropical system, and which describe something else? • What happens when a hurricane moves into cooler waters or over land – does it usually strengthen into a high, weaken into a low, or turn into a wave? • Think about where most strong winter storms over the U.S. come from – what kind of large-scale low-pressure system is that, and what is it called?

✅ Before You Answer

• Eliminate any choice that clearly means high pressure, since hurricanes are always associated with low pressure centers • Decide which options are tropical phenomena versus non‑tropical (frontal) systems • Recall the term used for low‑pressure systems that form or operate outside the tropics, often along frontal boundaries
