Abstract
Relationships of three Southern Oscillations and a few other large-scale atmospheric indices, like Stratospheric Quasi-Biennial Oscillation, Northern Hemispheric surface air temperature, 50 hPa subtropical ridge position, Indian monsoon rainfall, with the movement and formation of the tropical cyclones over the Bay of Bengal during the post-monsoon season are examined. In general, these relationships are not very satisfactory. However, there is some indication that the low phase of the Southern Oscillation is associated with lower mean latitude of the tracks of cyclones.
