According to the study, this is possible because due to this dust, the Arabian Sea is heated, which is the energy source for the movement of moisture-laden winds in the Indian region.
The researchers said this relationship is stronger now during years of drought caused by El Nio (oceanic currents). El Nio and El Nia are climate patterns of the Pacific Ocean that have the potential to change climates around the world.
Researchers have indicated that rain from this dust has an effect on the entire South Asian monsoon and acts as an artery to increase rainfall even during drought conditions.
V Vinoj, assistant professor in the School of Earth Oceans and Climatology at IIT Bhubaneshwar, said, “The Indian region is facing massive rainfall deficit due to climate change and the monsoon pattern has also changed.”
“However, with the increase in global temperature and change in wind direction, we can expect more dust storms in West Asia in the coming years,” Vinoj said. Under favorable conditions, these dust particles can be transported up to the Arabian Sea and this can bring short-lived but heavy rains over the Indian region.
Gopinath Nandini and Satyendra Kumar Pandey of IIT Bhubaneswar are involved in this research. The researchers also established that rainfall has decreased due to anthropogenic actions and that this pattern will continue for decades to come.
