🔍 Key Concepts

• Difference between storms that form over warm ocean water vs. storms that originate over land • Common maritime term for a small, intense rotating column of air over a body of water • How the same basic weather phenomenon can have different names depending on where it occurs and how it forms

💭 Think About

• Ask yourself: Is this phenomenon simply a continuation of the same rotating column of air that began over land, or a large organized storm system that develops over the ocean? • Consider the typical size and wind scale: is it a massive regional storm, or a local, relatively small rotating column over the water? • Think about which option mariners most often use to describe narrow funnel-shaped vortices seen over lakes or coastal waters.

✅ Before You Answer

• Verify which term is commonly used in marine weather forecasts and pilot charts for narrow, funnel-like rotating columns over water. • Check which choices usually describe large-scale storm systems (covering hundreds of miles) rather than a single concentrated vortex. • Be sure the term you pick is specifically associated with water surfaces and not just any rotating storm over land.
