Abstract

The growth rates of atmospheric methane measured at several locations distributed over the globe during 1983-92 were subjected to spectral analysis. Significant Quasi-biennial (2-3 years) and Quasi-triennial (3-4 years) oscillations were noticed at several locations but not simultaneously at all locations. The periodicities were bunched at 2.10-2.44, 3.1-3.5 and 3.9-4.8 years and, in some cases, matched with the 2.54 year periodicity of 50 hPa equatorial zonal wind and/or ~2.30 year and ~4.5 year periodicities of ENSO.
