Boundary Layer Oscillations from Thunderstorms at Sydney Airport

Abstract

Abstract Analyses of wind velocity and air pressure data, acquired by a set of low-level anemometers at Sydney Airport, Australia, indicate the passage of a set of three remarkably smooth atmospheric boundary layer oscillations that traveled ahead of a thunderstorm on 27 December 1991. The oscillations were probably generated by a nearby thunderstorm outflow, propagating into a stably stratified atmospheric layer. It is likely that the …
