摘要

This study is mainly concerned an application of the spectral tehnique analysis in investigating the anomalous change of the Quasi-Biennial Oscillation (QBO) over the equatorial region, especially over the Singapore related to the ozone's concentration at about 50 hPa. This is important since we need to know that characteristics of ozone concentration at that layer due to the ozone depletion caused by the effect of the global warming. Please note here, ozone is already stated as one of the most important parameter needed to protect our earth from Ultra Violet (UV) light. No much study of ozone's protection, especially near the equatorial region. In this preliminary results, we show the characteristics of QBO taken from the Singapore 's QBO data analysis. The QBO has represented as the downward propagating of zonal wind variation. Then, we investigate impact of QBO on the Ozone's Concentration anomaly at stratospheric layer. We found the pre-dominant peak oscillation of QBO at around 28 month. We found also an a good agreement (pattern) between QBO and Ozone's Concentration anomaly, especially at 50 hPa layer with a correlation coefficien of about 0.5. By this formula, we can estimate the next behavior of ozone's concentration anomaly taken from the QBO index that updated regularly.
