摘要：
The impact of tropical cyclones formed over the Arabian Sea and Bay of Bengal on the total ozone derived from the Total Ozone Mapping Spectrometer aboard the Earth Probe satellite has been studied. We have analysed the perturbations caused in the total amount of ozone due to four severe tropical cyclones. The daily total ozone anomalies have been calculated for the lifespan of each tropical cyclone. Theses anomalies were observed to be local in character and moved with the tropical cyclone. Further, these anomalies are related to the intensification of the cyclonic systems. In general, negative anomalies were observed to be more than 20 Dobson Units at the time of maximum intensity of cyclones. Variations in daily total ozone anomalies, from development to intensification stage and then to decaying stage of each cyclone have brought out clearly the impact of tropical cyclone on the total ozone, which got depleted considerably over the affected region.
