Planetary waves observed by TIMED/SABER in coupling the stratosphere-mesosphere-lower thermosphere during the winter of 2003/2004: Part 1-Comparison with the UKMO temperature results

摘要

Part 1 of the present paper is focused on the types of planetary wave seen in the TIMED/SABER and UK Met Office (UKMO) temperature data in the Northern Hemisphere (NH) (0-50 degrees N) stratosphere (30-60 km) during the Arctic winter of 2003/2004, as the emphasis is on their spatial structure (latitude and altitude) and temporal evolution particularly in relation to the stratospheric warmings. A new method for analysis of satellite data is presented in this study where the migrating and nonmigrating tides and planetary waves (stationary, zonally symmetric and travelling) are simultaneously extracted from the satellite data. The comparison between the altitude and latitude structure of the SABER and UKMO planetary waves in the temperature field of the NH stratosphere indicates a high degree of qualitative and quantitative resemblance and in this way the validity of the new data analysis method is verified as well.
