Estimating Enhanced Fujita Scale Levels Based on Forest Damage Severity

Weather and Forecasting, 2017
Abstract Enhanced Fujita (EF) scale estimates following tornadoes remain challenging in rural areas with few traditional damage indicators. In some cases, such as the 27 April 2011 tornadoes that passed through mostly inaccessible terrain in the Great Smoky Mountains National Park and the Chattahoochee National Forest in the southeastern

Evaluating the Utility of NDVI as a Damage Indicator for Crops in the Enhanced Fujita Scale

Journal of Applied Meteorology and Climatology
Abstract Tornadoes in Canada frequently impact rural regions, particularly croplands, where traditional enhanced Fujita scale (EF scale) assessments are limited due to the absence of standard damage indicators. Not knowing the true intensities of these tornadoes results in an inaccurate tornado climatology for these regions.

On the Consistency between the Fujita and Enhanced Fujita Scales and Implications for the U.S. Tornado Climatology

Monthly Weather Review
Abstract The Fujita (F) and enhanced Fujita (EF) scales have formed the baseline for tornado intensity estimation in the U.S. tornado climatology. Ahead of the EF scale’s debut in 2007, one stated goal was to maintain consistency in the ratings between the two scales (i.e., a rating from the EF scale would have the same climatological “meaning” as a ...

Major tornadoes in the Netherlands: Reconstruction and re-rating using the International Fujita scale

The Netherlands lie within a broad zone stretching from western France into northwestern Germany where strong tornadoes (rated IF2 and above) occur more frequently than in areas further south and east. Throughout the 19th and 20th centuries, the country experienced several powerful tornadoes, as well as multiple outbreaks that also affected neighboring

Revisiting a 24-year database of tornado damage paths using the new International Fujita (IF) scale

Tornadoes are the meteorological phenomenon capable of producing the most intense surface winds in the Earth, sometimes exceeding 100 m s-1. Tornado wind speed can rarely be measured in-situ using anemometers and radar. Nevertheless, it can be estimated through an analysis of the observed damage, especially when performing in-situ damage surveys (Rodr ...

How Have the Intrinsic Characteristics and Application of the Enhanced Fujita Scale Contributed to a Decreased Frequency of Intense Tornadoes in the United States?

Journal of Applied Meteorology and Climatology
Abstract Recent research has shown that the rating frequency for intense tornadoes (rated ≥EF3 on the Enhanced Fujita or EF scale) dating back to 2014 is at a historical low relative to both the real-time Fujita-Scale rating era (1977–2006) and the early years of the EF-scale rating era (2007–2013, with or without the catastrophic ...
