Dynamics of a solar prominence tornado observed by SDO/AIA on 2012 November 7-8 [PDF]
, 2015 We study the detailed dynamics of a solar prominence tornado using time series of 171, 304, 193 and 211 {\AA} spectral lines obtained by Solar Dynamics Observatory/ Atmospheric Imaging Assembly during 2012 November 7-8. The tornado first appeared at 08:00 UT, November 07, near the surface, gradually rose upwards with the mean speed of $\sim$ 1.5 km s$^{

Condensational theory of stationary tornadoes [PDF]
Physics Letters A, 375, 2259-2261 (2011), 2012 Using the Bernoulli integral for air streamline with condensing water vapor a stationary axisymmetric tornado circulation is described. The obtained profiles of vertical, radial and tangential velocities are in agreement with observations for the Mulhall tornado, world's largest on record and longest-lived among the three tornadoes for which 3D ...

Using Overshooting Top Area to Discriminate Potential for Large, Intense Tornadoes
Geophysical Research Letters, 2019 Recent work established strong links between storm updraft width and the tornado intensity, suggesting that updraft width could be used to gauge potential tornado intensity.

Navigating Storms: Examining Vultures’ Behavior in Response to Extreme Weather Events
Diversity, 2023 Extreme weather events such as hurricanes and tornadoes have been found to change the spatial and temporal abundance of raptors by decreasing survival and forcing the emigration of individuals, or by increasing habitat heterogeneity and facilitating ...

A proposal to fight tornadoes with multiple connected balloons [PDF]
arXiv, 2020 A tornado is an extreme weather condition that can cause enormous damage to human society. In this paper, we propose a low cost, environmentally friendly method to fight against tornadoes using clusters of connected balloons. Deployed over a sufficiently wide area, these large balloons may be able to reduce the wind speed of the tornado, block and ...

Untwisting the Tornado: X-ray Imaging and Spectroscopy of G357.7-0.1 [PDF]
Astrophys.J. 594 (2003) L35-L38, 2003 We report on the detection of X-ray emission from the unusual Galactic radio source G357.7-0.1 (the "Tornado"). Observations made with the Chandra X-ray Observatory demonstrate the presence of up to three sources of X-ray emission from the Tornado: a relatively bright region of dimensions 2'x1' coincident with and interior to the brightest radio ...

Applications of vortex gas models to tornadogenesis and maintenance [PDF]
, 2017 Processes related to the production of vorticity in the forward and rear flank downdrafts and their interaction with the boundary layer are thought to play a role in tornadogenesis.

Plasma Tectonics and Electric Geology: Some Context on Geoplasma Research of Global Electric Circuits [PDF]
Journal of Systemics, Cybernetics and Informatics, 2020 Has anyone ever wondered why tornado outbreaks generally occur in the Spring, while hurricane season is in the Fall? The tilting of the Earth's North Pole towards the Sun in the Spring activates the northern global circuits connected to North America ...

On the magnetism and dynamics of prominence legs hosting tornadoes
, 2016 Solar tornadoes are dark vertical filamentary structures observed in the extreme ultraviolet associated with prominence legs and filament barbs. Their true nature and relationship to prominences requires understanding their magnetic structure and dynamic
