Enhanced Fujita Scale Revisions by 2030

The Revised Enhanced Fujita Scale (EF Scale) by 2030

The purpose of revising Enhanced Fujita scale aims to expand beyond current 28 damaging indicators, integrate mobile radar data, and potentially re-evaluate historical tornado ratings.

*The revised EF scale will have updated wind metrics to calculate tornado wind speed, overall numeral rating scale will remain EF0 to EF5*

- Expanded Damage Indicators:

- Grain Bins

- Silos 

- Crop integration systems that lack current structural failure metrics 

- Mobile Radar Integration:

Use real-time mobile velocity data alongside traditional post-storm ground engineering surveys 

- Historical Tornado Re-Evaluation:

This will allow past storms that produced tornadoes to be re-evaluated for missing traditional structural targets by using modern day framework for a more accurate EF rating.

- Forensic Engineering Analysis:

Structural connection diagnostics - Evaluators actively looking for broken links in structural load paths, such as how walls were attached to foundations or roofs to walls.)

Accounting for Poor Construction - Evaluators will use forensic analysis to reveal if structure is missing anchor bolts, rotten wood, ect. The wind speed estimate required to cause that damage will be adjusted downward.

Forensic Re-Analysis of Complex Damage: 

Heavy Object Ballistics - Forensic teams will calculate the weight, aerodynamic drag and distance traveled by non-traditional missiles - (ex: Train Tankers thrown like during Enderlin, ND tornado) to back-calculate ground-level wind velocity. 

Treefall Kinematics - Advanced forensic modeling will map treefall patterns and mathmatical wind-resistance levels over forested areas, transforming messy tree damage into a more precise, multi-layered wind speed indicator. 

The overall purpose of revising the Enhanced Fujita Scale is to implement advanced tornado science to improve accuracy rating tornadoes, moving away from subjective opinions of EF ratings after a tornado event in the United States.
