摘要：
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 degrees 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.
