Abstract

In this paper we describe a case study of progressive gravity waves in the troposphere. We deduce their propagation speed and direction, and their dispersive characteristics, from surface spectra of wind and pressure. We compare the results with direct measurements of the waves made over an array of spaced pressure sensors using cross spectrum techniques and an algorithm developed by one of us (Young). The agreement is very satisfactory and demonstrates the feasibility of monitoring atmospheric wave conditions in almost real time using only sensors (high quality) in use at standard weather observation stations. The waves in the case we describe were highly dispersive and apparently were generated by a violent thunderstorm some 100 km west of the site of observation.
