 In India, for example, 6 to 7 monsoon depressions move across the country yearly, and their numbers within the Bay of Bengal increase during July and August of El Niño events.Monsoon depressions are efficient rainfall producers, and can generate a year's worth of rainfall when they move through drier areas, such as the outback of Australia.Some tropical cyclones recognised by Regional Specialized Meteorological Centres would have characteristics of a monsoon depression throughout their lifetime.
