| Abstract: | Through the HALOE and SAGE II data, the Quasi-Biennial Oscillation characteristics of Stratospheric Aerosol have been analyzed. The relationship of aerosol QBO and ozone QBO has also been studied. The results indicate: (1) Stratospheric Aerosol QBO characteristics are obvious in high and middle latitude of northern hemisphere. Here the QBO signal propagates downward from 10 hPa to 50 hPa, and the oscillating amplitude can reach 20% in middle and lower stratosphere. However, in southern hemisphere or equator the Stratospheric Aerosol QBO characteristics are less apparent. (2) There is a strong correlation between the aerosol QBO and ozone QBO in the middle and low stratosphere of northern hemisphere. The correlation is apparently positive over the low and high latitude while it turns to be negative at 30 hPa over the middle latitude. (3) The aerosol surface density is positive anomaly in 30~10 hPa of northern hemisphere during easterly phase of tropical zonal wind and the anomaly percentage can reach 20%. It changes to negative anomaly during westerly phase. The variation of aerosol surface density is closely related to the transportation of aerosol by residual circulation. |
