The Bangladesh cyclone of 15–22 November 1992 was observed by the scatterometer onboard the ERS-1 satellite. The unique data set from this scatterometer (which is the first of its kind over an Indian Ocean cyclone) has been analysed in order to study various features of the cyclone. A new technique to estimate the centre of the cyclone objectively from the observed winds has been proposed. Based on the precise knowledge of the centre, the directional ambiguity of the wind data has been removed.
