An observational study of medium-scale wave dynamics in the Southern Hemisphere summer. Part I: wave structure and energetics.

Abstract

Medium-scale waves (zonal wavenumbers 4-7) frequently dominate Southern Hemisphere (SH) summer midlatitude circulation patterns. This work is an observational study that focuses on their temporal and spatial characteristics, along with detailing the forcing mechanisms responsible for their formation. Medium-scale wave characteristics for three SH summers (1978/79 through 1980/81) are discussed. -from Authors
