Intra-seasonal oscillations in the central Bay of Bengal during summer monsoon 1999

Intra-seasonal oscillations were observed in the meteorological and océanographie fields of Bay of Bengal during the summer monsoon season of 1999. Spectral analysis revealed prominent peaks in the intra-seasonal (10 to 32 days), inertial (2.2 days), diurnal and semi-diurnal bands. Oscillation of in...

Zusammenfassung:Intra-seasonal oscillations were observed in the meteorological and océanographie fields of Bay of Bengal during the summer monsoon season of 1999. Spectral analysis revealed prominent peaks in the intra-seasonal (10 to 32 days), inertial (2.2 days), diurnal and semi-diurnal bands. Oscillation of intraseasonal periodicity significantly influences the circulation pattern. The variations in océanographie fields were dominated by remote forcing compared to local forcing.
