Evidence for 35-50 day low frequency oscillations in total ozone mapping spectrometer data

A large number of investigations are currently focused on low frequency oscillations (LFO) of the tropical atmosphere, with periods of one to two months. Recently, the existence of LFO in the stratosphere has been postulated by global circulation model results and also by observations based on satellite microwave and infrared data. However, the observational results are not well captured by the model calculations. The present work utilizes an independent set of satellite data (four years of data from the Total Ozone Mapping Spectrometer (TOMS), between latitudes 65N and 65S) as a check on the previous observational analyses. Evidence is found for the existence of 3550 day oscillations in the TOMS data over the Southeast Pacific and South Indian Oceans, corroborating the earlier observational report.
