🔍 Key Concepts

• Multiple independent methods can often be used to locate or confirm a storm center • How Buys Ballot's Law relates wind direction to the location of low pressure in the Northern Hemisphere • Modern weather information sources available to ships at sea (e.g., radar, radio, weather fax)

💭 Think About

• Which option(s) describe a way to determine or estimate where the lowest pressure / circulation center of the storm is located relative to your ship? • Is any one of these methods clearly impossible or unrelated to finding the storm center, or do they all provide useful information? • Think about how mariners historically found storm centers before modern electronics, and how they do it now with technology.

✅ Before You Answer

• Verify which choices give direct information about the storm’s location (like plotted positions or visible circulation) • Check whether Buys Ballot’s Law can still help estimate the center if you have only wind observations and no electronics • Ask yourself if exam questions on storm location often favor using all available sources of information when they’re reasonable.
