What kind of pressure systems travel in...

🔍 Key Concepts

• Tropical waves and how they relate to larger storm systems like tropical depressions and hurricanes • The difference between high pressure and low pressure systems in terms of rising/sinking air and cloud formation • Basic weather rule: which type of pressure is usually linked with bad weather, clouds, and storms at sea

💭 Think About

• Think about what kind of pressure pattern is typically associated with the development of tropical storms and hurricanes • Ask yourself: in the tropics, when you see bands of showers and thunderstorms moving westward, what kind of pressure system is driving that? • Consider whether tropical waves are usually calm, clear‑weather systems or disturbed, stormy‑weather systems

✅ Before You Answer

• Recall that high pressure is usually connected with clear skies and more stable conditions • Recall that low pressure is generally tied to rising air, clouds, and unsettled or stormy weather • Eliminate any answer choices that do not describe a real or relevant atmospheric pressure system at the sea surface
