AR events impacted the country 596 times, 95% of which occurred during a monsoon season. They also found that 54% of the biggest AR events occurred over the past three decades, suggesting they are not only forming more often but are getting bigger as the planet grows warmer.
The researchers note that warmer ocean surface temperatures over parts of the Indian Ocean have led to more evaporation, which in turn has led to more rain when ARs form. The increase in rain amounts has led to massive floods which have destroyed property and killed thousands of people.
