Cyclones in the Indian Ocean and Bay of Bengal have long been a natural phenomenon, but the increasing frequency and intensity of these storms in recent years has raised concerns about the role of the climate crisis in their development. Scientists and research agencies have been studying the link between climate change and cyclones, providing valuable insights into the complex relationship between the two.
Warming Ocean Temperatures
One of the key factors contributing to the intensification of cyclones in the Indian Ocean and Bay of Bengal is the warming of ocean temperatures. According to the Intergovernmental Panel on Climate Change (IPCC), global warming caused by greenhouse gas emissions has led to a significant rise in sea surface temperatures. The warmer waters provide the necessary energy for cyclones to develop and strengthen.
Research conducted by the Indian National Centre for Ocean Information Services (INCOIS) indicates that the Bay of Bengal has experienced a temperature increase of approximately 0.5 to 1 degree Celsius over the past century. This warming trend has made the region more favorable for cyclone formation and has contributed to their increased intensity.
Changes in Atmospheric Conditions
The climate crisis has also resulted in alterations to atmospheric conditions, influencing the development and behavior of cyclones. Rising levels of greenhouse gases, such as carbon dioxide, have led to changes in global atmospheric circulation patterns, including the monsoon systems that impact the Indian Ocean and Bay of Bengal.

Studies conducted by the Indian Institute of Tropical Meteorology (IITM) suggest that the intensification of the Indian Ocean Dipole, a climate phenomenon characterized by temperature differences between the western and eastern parts of the ocean, can influence the formation and trajectory of cyclones. A positive Indian Ocean Dipole, resulting from global warming, increases the likelihood of cyclones forming in the region.
Sea Level Rise and Coastal Vulnerability
Another significant impact of the climate crisis on cyclones in the Indian Ocean and Bay of Bengal is the rising sea levels. Research conducted by the National Oceanic and Atmospheric Administration (NOAA) indicates that sea levels have risen at an accelerated rate in recent decades due to climate change. This rise exacerbates the risk of storm surges and coastal flooding during cyclones, posing severe threats to vulnerable coastal communities.
The climate crisis is undeniably influencing the development and characteristics of cyclones in the Indian Ocean and Bay of Bengal. Warming ocean temperatures, changes in atmospheric conditions, and rising sea levels are key factors that contribute to the increased frequency and intensity of these storms. The research conducted by institutions such as INCOIS, IITM, and NOAA has provided valuable insights into the complex relationship between the climate crisis and cyclone development.
Addressing the climate crisis requires global cooperation and concerted efforts to reduce greenhouse gas emissions, promote sustainable practices, and enhance disaster preparedness and resilience in vulnerable coastal regions. By understanding the effects of the climate crisis on cyclone formation, we can strive to mitigate its impacts and protect lives and livelihoods in the Indian Ocean and Bay of Bengal.
