Abstract: A scientific campaign to delineate the characteristics of equatorial waves in the middle atmospheric wind field has been conducted in May-June 1984 from three equatorial stations, viz. Trivandrum (8.6°N, 77°E), SHAR (13.7°N, 80.2°E) and Balasore (21.5°N, 86.9°E), as part of the Indian Middle Atmosphere Programme (IMAP). The zonal and meridional wind data obtained in the campaign have been analyzed to characterize the fluctuating components in them. An interesting observation is the upward phase propagation of long period (12-20 days) zonal oscillation in the lower stratosphere. The present campaign revealed some features of the equatorial wave disturbances which are peculiar to the Indian zone. All the results of this study are presented and their implication and significance are discussed in the light of the current observational knowledge and theoretical background regarding the equatorial waves.
