摘要: The equatorial wave campaign-II which formed a part of the Indian Middle Atmosphere Programme (IMAP), was conducted from SHAR (13.7°N, 80.2°E) 15 January to 28 February 1986. Winds were measured ground 60 km by means high altitude balloon and meteorological rocket (RH-200), once everyday, for 45 days. frequencies oscillations in deviations east-west component winds its mean at each height with one kilometer interval obtained maximum entropy (ME) method phases/amplitudes these determined least squares technique on wind variation time series. ME has inherent advantage providing periodicities up 1.5 times data length.
