"Data from the network, called the research moored array for African-Asian-Australian monsoon analysis and prediction (RAMA), would also help scientists better predict the impacts of phenomena such as the Indian Ocean Dipole, a fluctuation in ocean surface temperatures.
When it is in a negative phase, it creates cool water west of Australia and warm Timor Sea water to the north. In a positive phase, the pattern of Indian Ocean temperatures is reversed, weakening the winds and reducing the amount of moisture picked up and transported across Australia.
Australian farmers were already using forecasting data about the dipole to plan their cropping."

Amazing how such a body of warm water can have a such a far reaching impact.
