Urbanization may enhance tornado potential: A single case report

open access: yesFrontiers in Earth Science, 2023
Tornadoes pose a risk of catastrophic economic loss and casualty in the United States. Modification of land use by urbanization alters the meteorological conditions that may impact tornado formation and intensification processes.

Dynamical Analyses of a Supercell Tornado in Eastern China Based on a Real-Data Simulation

open access: yesAtmosphere, 2023
Tornadoes are extremely destructive natural disasters, and East China has become a high-incidence area for tornadoes in China in recent years. On 7 July 2013, an EF2-intensity tornado occurred in Gaoyou County, Jiangsu Province in eastern China, within a

Infrasound measurement system for real-time in situ tornado measurements [PDF]

open access: yesAtmospheric Measurement Techniques, 2022
Previous work suggests that acoustic waves at frequencies below human hearing (infrasound) are produced during tornadogenesis and continue through the life of a tornado, which have potential to locate and profile tornadic events and provide a range of ...

A dynamic and thermodynamic analysis of the 11 December 2017 tornadic supercell in the Highveld of South Africa [PDF]

open access: yesWeather and Climate Dynamics, 2021
On 11 December 2017, a tornadic supercell initiated and moved through the northern Highveld region of South Africa for 7 h. A tornado from this supercell led to extensive damage to infrastructure and caused injury to and displacement of over 1000 people ...

Impact of the Streamwise Vorticity Current on Low‐Level Mesocyclone Development in a Simulated Supercell

open access: yesGeophysical Research Letters, 2023
Results from a large eddy simulation of a tornadic supercell developing in a horizontally homogeneous environment are presented which clearly illustrate a connection between low‐level mesoyclone development and the development of a streamwise vorticity ...

Analysis of the Three-Dimensional Structure of the Misocyclones Generating Waterspouts Observed by Phased Array Weather Radar: Case Study on 15 May 2017 in Okinawa Prefecture, Japan

open access: yesRemote Sensing, 2022
Tornadoes are one of the most severe meteorological phenomena on the earth and their high winds cause serious damage to society. It is well known that vortices (mesocyclone or misocyclone, depending on their scale) in convective clouds contribute to ...

DOW radar studies of the mechanisms for tornadogenesis, maintenance, and dissipation

open access: gold
Case studies of tornadic storms have shown the importance of various sub-storm scale structures, including in updrafts/downdrafts and associated convergence/divergence regions in tornadogenesis and intensification.  But, the existence of the features alone is not sufficient for tornadogenesis.
