Vortex wavelength

The Airborne Submillimeter SIS Radiometer (ASUR), operated on-board the German research aircraft FALCON, measures thermal emission lines of stratospheric trace gases at submillimeter wavelength. Measurement campaigns with respect to ozone depletion in the Arctic winter stratosphere were carried out in yearly intervals from 1992-97 to investigate the distributions of the radical chlorine monoxide (CIO), the reservoir species hydrochloric acid (HC1), the chemically inert tracer nitrous oxide (N20), and ozone (O3). The high sensitivity of the receiver allowed to take spatially well resolved measurements inside, at the edge, and outside of the Arctic polar vortex. This paper focuses on the results obtained for CIO from...

Think of an uncurved vortex filament as a stack of normal two-dimensional rotors, each radiating a spiral of wavelength Aq in the horizontal plane. Twist the stack uniformly by one full turn in altitude Ittw. The diagonal separation of outgoing wave fronts. A, then satisfies... 

As expected from numerical experiments with diverse other excitable media, vortex rings in Oregonator media with ferroin and bromous acid diffusing freely were found to commonly contract at an area rate close to 2tvD in units of cm and seconds (or 0.06, in units of wavelength and period), in general...
