Abstract
Intra-seasonal oscillations were observed in the meteorological and oceanog raphic fields of Bay of Bengal during the summer monsoon season of 1999. Sp ectral analysis revealed prominent peaks in the intra-seasonal (10 to 32 da ys), inertial (2.2 days), diurnal and semi-diurnal bands. Oscillation of in traseasonal periodicity significantly influences the circulation pattern, T he variations in oceanographic fields were dominated by remote forcing comp ared to local forcing.
