It is December and we are witnessing heavy rainfall in parts of India. The weather department has forecast sporadic rains in Mumbai and its suburban region in the next 24 hours.
Schools and colleges in Maharashtra were declared shut on account of rain. Cyclone Ockhi, which is currently making its way up the western coast of India, has already disrupted life in the Kanyakumari region.
The unprecedented Mumbai rains has broken a decade-long streak of the December rain record.
So why do cyclones occur?
Tropical cyclones were defined as ‘giant engines’ by NASA. These engines use warm, moist air as fuel.
“That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface,” NASA said.
“The increased incidence of hurricanes and cyclones as well as their greater intensity is no natural phenomenon,” said Suren Abreu, environmental activist and feminist.

“We are seeing such an upsurge in these storms that we have to conclude to a definite link to human behaviour. Despite the views of naysayers and climate change deniers, climate change is very real, very alarming. The huge load of CO2 in the atmosphere that is only due to human activities (rapid industrialisation, deforestation, fossil fuel burning, electrification, to name a few) has caused atmospheric and surface temperatures to rise significantly,” Abreu added.
How bad is Cyclone Ockhi?
The cyclone gets its name from an active tropical cyclone. It has been the most intense to traverse the Arabian Sea.
Cyclone Ockhi was described by analysts as a ‘very severe cyclonic storm.’ “The severe deforestation across the globe further disrupts rainfall and wind direction,” Abreu said.
Over 500 fishermen who were stranded in the sea off Kerala and Lakshadweep coasts were rescued on Saturday. However the death toll went up to 14 over the weekend.
