Abstract
Southern Hemisphere atmospheric circulation and sea surface temperatures in the South Indian Ocean, associated with the South Indian Convergence Zone (SICZ), the main rain producing system over southern Africa, and links with rainfall over Mozambique, are analysed. Cluster analysis applied to gridded outgoing long-wave radiation data, were used to identify convective activity related to the tropical temperate troughs that collectively form the SICZ. Intraseasonal and inter-annual variability of these systems and their contribution to the anomalies of rainfall over Mozambique were explored using composite, correlation and regression analyses for both the early (October to December) and the late (January to March) summer.
