Abstract

After correcting for seasonal variations and long‐term (linear or quadratic) trends, the residual interannual anomalies (variations) of the trace elements and surface aerosol show periodicities in the Quasi‐biennial Oscillation (2–3 years) and 3–5 years range. Quasi‐biennial Oscillations (QBO) of some elements match with the QBO of equatorial 50‐hPa wind, but for some others, matching is not good. For some elements, matching with Southern Oscillation index is good. The relationship is probably through the sea‐surface temperature changes, which affect the role of the ocean as a source/sink for these trace elements. Interaction between equatorial wind QBO and extratropical phenomena should also be involved.
