Abstract

When subjected to a spectral analysis, the series of the frequency of monsoon depressions and storms formed over the north Indian Ocean area (5° N - 35° N, 50° E - 100° E, Bay of Bengal and the Arabian Sea taken together) for 1890-1999 indicated (a) a highly significant periodicity at T = ~40 years, and barely significant periodicities at T = 2-3 (QBO), 3.7, 4.6, 8.8, and 21.8 years for cyclonic disturbances, and (b) a highly significant periodicity at           T = ~37 years, and significant periodicities at T = 2-3 (QBO), 11.4, and 15.4 years for cyclonic storms.
