At the beginning of spring 2022, South Asian countries, including India, Pakistan and Afghanistan, experienced extreme thermal waves in March and April.
A study published on April 8, 2025 Scientists from the Indian Institute of Technology (IIT) Bombay and Johannes Gutenberg-University Mainz, Germany, revealed why South Asian countries experienced an extreme back.

In a study called “Contrast Drivers of the Pre -Moist South Asian Thermal Waves in 2022: Interaction of the waveguard and depletion of soil moisture published in the Journal of Geophysical Research: Atmosphese, scientific atmospheric research magazine published by the American Geophysical Union; The waves in March and April 2022 were powered by various atmospheric processes that complicated the impact of wool wool.
The manager of the study Roshan Jha, a doctoral student at the Center for Climate Studies, IIT Bombay, said: “Our analysis shows that the waves of March waves were primarily associated with a sudden increase in short -term atmospheric wave amplitude, which are approaching the wind winds. current) transferred energy to the western winds closer to the equator (subtropical current of the current) when they approached during the thermal wave.
April-Vlna Thermal waves took place differently as in, instead of being driven by wind patterns at high altitude, it was largely caused by very dry soil conditions and heat council to India from Northwest of Pakistan and Afghanistan. Co -author of the study, Arpita Mondal, associate professor at the Department of Civil Engineering and Center for Climatic Studies in IIT Bombay, explained that these dry conditions were partially created by the former wave wave, which has already dried the soil at high temperatures and a clear sky.
“This Research Reveals and Concerning Pattern: One Heatwave Can Set the Stage for Another, MORE INTENSE Heat Event in the Following Weeks Moisture From the Soil. When Soil Becomes Too, It Creates and Cycle that Makes The Nex When the Sun’s Energy Goes into Evapoating That Moisture Rather Than Heating the Air, the soil is alley, all that Energy Goes Straight In Making The Air, ”explained.
IIT Bombay Subimal Ghosh, Center for Climate Studies, IIT Bombay and Professor at the Ministry of Construction, said that understanding these mechanisms is essential for improving our ability to predict and prepare for extreme thermal events in South Asia. “Since climate change continues to affect atmospheric wind patterns, identification of these specific drivers helps us to predict and alleviate the impact of future wave waves,” he added.
