Electromagnetic fields recorded in mesocyclones.(Report)
Initial findings taken from ongoing field research, seeking to better understand the relationships between electrical charge, magnetic fields, and the evolution of vortices, are presented. Despite inherent difficulties in collecting real-time data associated with vortices, measurements of magnetic fields close to and within dust devils, mesocyclones, and a hurricane were successively recorded using magnetometers.
Speculations about possible mechanisms accounting for the variability in the electromagnetic fields observed are offered, although without quantitative proof. Of particular interest for additional research are: i) measurements showing an increase in the ...
