Anand M. Sharan

Monsoon rain prediction, annual rainfall, rainfall frequency spectrum, El Nino and La Nina influence on rainfall, drought and famine, crop failure.

Life in India is sustained by monsoon rains because about 70% of agriculture here relies solely on these rains. In this work, the results of four methods are combined to arrive at the final result. These methods are: (1) Time Series method,(2) Fast Fourier Transform (FFT) method,(3) Artificial Neural Network (ANN) method and (4) Root Means Square (RMS) method. The final result indicates that this year - there will be about 8% less rain amount than the average of past 32 years.
