Geostrophic balance over the Arabian Sea and Bay of Bengal regions

Geostrophic balance over the Arabian Sea and Bay of Bengal regions has been studied using the wind data obtained from the AVRO (HS-748) aircraft during the FGGE-MONEX-79. In the Arabian Sea and the Bay of Bengal regions, the observed wind south of 20 degree N was found to be sub-geostrophic. In the...

Zusammenfassung:	Geostrophic balance over the Arabian Sea and Bay of Bengal regions has been studied using the wind data obtained from the AVRO (HS-748) aircraft during the FGGE-MONEX-79. In the Arabian Sea and the Bay of Bengal regions, the observed wind south of 20 degree N was found to be sub-geostrophic. In the Arabian Sea region the departure at 1500 m was 75-95% and at 3050 m it was 60-65%. In the Bay of Bengal region the departure was 35-95%. In a few cases north of 20 degree N the observed winds at 3050 m were found to be super-geostrophic in the regions of enhanced monsoon activity, cyclonic circulation reaching up to 6000 m and the region of monsoon trough.
