| Zusammenfassung |
| The interaction between the factors of the
quasi-biennial oscillation (QBO) and the 11-year solar cycle is considered as an
separate factor influencing the interannual January-March variations of total
ozone over Northeastern Europe. Linear correlation analysis and the running
correlation method are used to examine possible connections between ozone and
solar activity at simultaneous moment the QBO phase. Statistically significant
correlations between the variations of total ozone in February and, partially,
in March, and the sunspot numbers during the different phases of QBO are found.
The running correlation method between the ozone and the equatorial zonal wind
demonstrates a clear modulation of 11-y solar signal for February and March.
Modulation is clearer if the QBO phases are defined at the level of 50 hPa
rather than at 30 hPa. The same statistical analyses are conducted also for
possible connections between the index of stratospheric circulation C1
and sunspot numbers considering the QBO phase. Statistically significant
connections are found for February. The running correlations between the index C1
and the equatorial zonal wind show the clear modulation of 11-y solar signal for
February and March. Based on the obtained correlations between the interannual
variations of ozone and index C1, it may be concluded that a
connection between solar cycle – QBO – ozone occurs through the dynamics of
stratospheric circulation. |
