Indian Monsoon Rainfall

Advancing Indian Monsoon Rainfall Predictions

Despite great strides made in seasonal climate forecasting using dynamical models, skill in predicting the Indian monsoon is woefully poor. Our analysis of the reasons for failure exposes a flaw in the popular design of dynamical prediction systems. The approach of driving atmospheric models with a projected ocean surface temperature presupposes Indian monsoon variability to be a consequence so...

Advancing dynamical prediction of Indian monsoon rainfall

[1] Despite advances in seasonal climate forecasting using dynamical models, skill in predicting the Indian monsoon by such methods has proven poor. Our analysis identifies a flaw in the hitherto popular design of prediction systems in which atmospheric models are driven with a projected ocean surface temperature. Such a configuration presupposes Indian monsoon variability to be a consequence s...

Long-term variations in winter rainfall of southwest Australia and the African monsoon

The rainfall in southwest Western Australia (SWWA) mostly falls in May to September, and predominantly in June, July and August (JJA). Records show that, prior to the 1960s, this area had the most reliable rainfall in the country, but in the late 1960s a decrease of approximately 20 per cent (from approximately 3.8 mm/day to 3 mm/day for JJA) occurred in the longterm mean (IOCI 2002), which per...
