Optics Letters, 2020 We show that light spiraling like a tornado can be generated by superimposing abruptly auto-focusing ring-Airy beams that carry orbital angular momentum of opposite handedness. With different parabolic propagation trajectories, the superimposing ring-Airy beams are tailored to abruptly auto-focus at overlapping focal regions. This

Kinetic Energy of Tornadoes in the United States. [PDF]
PLoS ONE, 2015 Tornadoes can cause catastrophic destruction. Here total kinetic energy (TKE) as a metric of destruction is computed from the fraction of the tornado path experiencing various damage levels and a characteristic wind speed for each level.

Assessment of tornado hazard in the nuclear facilities siting areas [PDF]
Nuclear Technology and Radiation Protection, 2020 The potential hazard of destructive tornado effects on nuclear facilities determines the necessity to study the climatic regime of tornado passage and arrange the appropriate protection of these facilities in conformity with the national and ...

Trend Analysis of U. S. Tornado Activity Frequency
Atmosphere, 2022 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. (

Comprehensive analysis of tornado statistics in comparison to earthquakes: intensity and temporal behaviour [PDF]
Nonlinear Processes in Geophysics, 2013 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

Population Bias on Tornado Reports in Europe
Applied Sciences, 2021 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.

Tornadoes in Australia: are we prepared? [PDF]
, 2022 Australian summers are periods of extensive and severe weather events. This often includes rapid-onset events of intense rainfall, flooding, hail, damaging winds and, in some instances, reported tornadoes.

Tornadoes in a microchannel [PDF]
Physics of Fluids, 2009 In non-dilute colloidal suspensions, gradients in particle volume fraction result in gradients in electrical conductivity and permittivity. An externally applied electric field couples with gradients in electrical conductivity and permittivity and, under some conditions, can result in electric body forces that drive the flow unstable forming vortices ...

The Climatology of Significant Tornadoes in the Czech Republic
Atmosphere, 2020 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 ...
