The Enhanced Fujita scale (abbreviated EF-Scale) is a scale that rates tornado intensity based on the severity of the damage a tornado causes. It is used in the United States, Brazil and France, among other countries. The EF scale is also unofficially used in other countries, including China. The rating of a tornado is determined by conducting a tornado…

Important terminology
Frequent words and multi-word phrases across the lead, headings, infobox and body. Useful for terminology coverage.
Use these terms to understand the vocabulary surrounding the topic, not as a checklist for keyword stuffing.
Relationships are represented as Subject → Predicate → Object triples. Confidence describes extraction strength, not the real-world importance of a relationship; lower-confidence rows may be contextual rather than explicit.
TTTA extracted 72 structured relationships around Enhanced Fujita scale. Examples in this analysis include Enhanced Fujita scale → is a → damage scale and only an estimate for actual wind speeds and differences in construction quality → instance of → and better accounts for variables.

Related concept clusters Related term clusters
Related term clusters group terms that sit near one another in the extracted graph. They are useful for discovering adjacent language and context, but proximity does not by itself imply a factual relationship.
The concept neighborhoods around Enhanced Fujita scale bring nearby vocabulary together. In this analysis, examples include Fujita, Scale and Damage. Use the clusters to find adjacent concepts and terminology that may deserve separate research.

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Enhanced Fujita scale, one of the stronger structural bridges in this analysis connects Enhanced Fujita scale with History. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
