The Indian Ocean temperature affects monsoon rainfall in India. The sea surface temperature in a specific area of the Indian Ocean is linked to monsoon rainfall and weather patterns. Higher temperatures in November lead to more rainfall the following year. Changes in ocean temperatures can impact weather patterns in distant regions like Australia and Indonesia. The study shows a connection between ocean temperatures and the Southern Oscillation, a climate phenomenon. This research helps us understand how the Indian Ocean influences weather patterns in different parts of the world.
