It affects the Indian subcontinent, where it is one of the oldest and most anticipated weather phenomena and an economically important pattern every year from June through September . Yet it is only partly understood and notoriously difficult to predict . Several theories have been proposed to explain the origin, process, strength, variability, distribution, and general vagaries of the monsoon, but understanding and predictability are still evolving . </P> <P> The unique geographical features of the Indian subcontinent, along with associated atmospheric, oceanic, and geophysical factors, influence the behavior of the monsoon . Because of its effect on agriculture, on flora and fauna, and on the climates of nations such as India, Nepal, Bangladesh, Bhutan, Pakistan, and Sri Lanka--among other economic, social, and environmental effects--the monsoon is one of the most anticipated, tracked, and studied weather phenomena in the region . It has a significant effect on the overall well - being of residents and has even been dubbed the "real finance minister of India". </P>
