Résumé
Rainfall has a substantial influence on agriculture, rural industries, food security and water quality. However, different parts of the world, especially many regions of Australia, often experience rainfall extremes of floods and droughts, and hence the inhabitants struggle to adapt to the diverse rainfall climate. Better understanding of the various characteristics of rainfall amounts in any region (variability in rainfall, distribution of rainfall totals, potential predictors of rainfall, etc.) is the first step towards adaptation. The first aim of the research was to develop measures to quantify the consistency in monthly rainfall totals of Australian stations. Then the various characteristics of the monthly and the seasonal rainfall totals of Australian stations were studied using well fitting theoretical probability distributions. Finally, appropriate statistical models are fitted to the monthly rainfall totals to simulate and predict rainfall, and to find the potential predictors of monthly rainfall totals of Australian rainfall stations.
