Summary

 In this paper the modulation of storm and depression tracks over North Indian Ocean by the Quasi-Biennial Oscillation (QBO) of zonal winds in the equatorial stratosphere is discussed for the period 1953–1991. It was observed that during post monsoon season the storms and depressions of Bay of Bengal were mostly confined to south of 17° N and move in west/North-westward direction during easterly phase of QBO. However during the westerly phase no such similar type influence of QBO on the system tracks was observed. Also such type of QBO-System tracks association was not observed during pre-monsoon season.
