<p>The cyclones that originated in the Bay of Bengal between 1864 and 1942 had immensely contributed to the emergence of various scientific theories regarding climatic disturbances and meteorological developments occurring in the Bay of Bengal. These ‘scientific theories’ regarding the origin and circulation of cyclones had demonstrated the plural worlds of Indian meteorology which had witnessed competition and collaboration of ideas among the colonial meteorologists. Unfolding the critical relationship between colonial science and the political economy of disaster, the present study would critically investigate the evolution of various meteorological theories developed throughout the colonial period for understanding the shifting perspectives of the colonial meteorological research. Focusing critically on the epistemological value of the colonial meteorological knowledge, the article intends to highlight the conflict of ideas among the meteorologists regarding the occurrence of various climatological phenomena, the limitations of various meteorological theories as highlighted by the meteorologists themselves, and contradictory understanding of the sailors and the meteorologists regarding the ‘practical’ value of the research. The paper also examines the historical trajectories of the concept of cyclone-warning and public-safety, and examines to what extent the colonial government was successful in providing adequate cyclone-warning to the mariners and the common people.</p>
