Trend Analysis of U. S. Tornado Activity Frequency
As one of the most severe and high-impact weather phenomena, tornadoes and their long-term frequency trends have received lots of attention from both the scientific community and the public. Here, we show that over the last six decades (1954–2018), U.S. (

Climatological occurrences of hail and tornadoes associated with mesoscale convective systems in the United States [PDF]
Hail and tornadoes are hazardous weather events responsible for significant property damage and economic loss worldwide. The most devastating occurrences of hail and tornadoes are commonly produced by supercells in the United States.

Comprehensive analysis of tornado statistics in comparison to earthquakes: intensity and temporal behaviour [PDF]
Tornadoes and earthquakes are characterised by a high variability in their properties concerning intensity, geometric properties and temporal behaviour. Earthquakes are known for power-law behaviour in their intensity (Gutenberg–Richter law) and temporal

Spatial Distributions of Tropical Cyclone Tornadoes by Intensity and Size Characteristics
Tropical cyclones that make landfall often spawn tornadoes. Previous studies have shown that these tornadoes are not uniformly distributed in the United States or in the tropical cyclone environment.

Spatial–temporal clustering of tornadoes [PDF]
The standard measure of the intensity of a tornado is the Enhanced Fujita scale, which is based qualitatively on the damage caused by a tornado. An alternative measure of tornado intensity is the tornado path length, L.

Population Bias on Tornado Reports in Europe
Tornadoes are associated with damages, injuries, and even fatalities in Europe. Knowing the spatial distribution of tornadoes is essential for developing disaster risk reduction strategies.

The Climatology of Significant Tornadoes in the Czech Republic
In the Czech Republic, tornadoes may reach an intensity of F2 and F3 on the Fujita scale, causing “considerable” to “severe” damage. Documentary evidence is sufficient to allow the creation of a chronology of such events, from the earliest recorded ...

Occurrence of Anticyclonic Tornadoes in a Topographically Complex Region of Mexico
Tornadoes are violent and destructive natural phenomena that occur on a local scale in most regions around the world. Severe storms occasionally lead to the formation of mesocyclones, whose direction or sense of rotation is often determined by the ...
