EF Scale

免費
Rate tornado damage the way surveyors do. EF Scale puts the complete
Enhanced Fujita scale on your iPhone, iPad, and Mac — all 28 damage
indicators, every degree of damage, and the expected wind speeds
behind each rating.
Browse structure types from small barns and family residences to
high-rise buildings, transmission lines, and trees. Compare what you
see against reference photos and construction details, then pick a
degree of damage and tune the wind speed estimate between its bounds
to account for construction quality.
• All 28 damage indicators of the Enhanced Fujita scale
• Reference photos and construction details for every indicator
• Degrees of damage with expected wind speeds and EF ratings
• Interactive wind speed estimator with adjustable bounds
• EF0–EF5 rating reference, always a tap away
• Everything stored on device — works fully offline in the field
Built for storm spotters, damage surveyors, emergency managers,
students, and weather enthusiasts.
*** PLEASE REMEMBER: This app is for reference purposes only. Doing a real damage survey takes knowledge and experience you can't build into an app! Official damage assessments are the business of the National Weather Service and their delegates! ***
