| Zusammenfassung |
A relatively recent technique, the multi-resolution analysis (MRA), was
applied to the global total ozone column measured by the Nimbus-7 TOMS
instrument during 1979–1992. Ozone monthly averages were filtered in
orthonormal frequency bands using the Meyer wavelet transform, and the ozone
variability was analyzed in different time scales: high frequency
oscillations (2–4 months), semiannual variation (6 months), annual
variation, quasi-biennial oscillation (QBO), El Niño-Southern
Oscillation (ENSO) and solar cycle related variations. MRA was thus showed
to be an efficient band-pass filter to isolate different time scale signals.
QBO, ENSO and solar cycle related variations in global total ozone are
investigated in more detail through spectral and cross-correlation analyses.
