dc.description.abstract | We highlight some of the unrecognised aspects of land–atmosphere feedbacks that drive the summer season (March–May) temperature extremes and unleash compounding impacts in India, resembling other hotspots of the world. Analysing a variety of drought and heat metrics, we find persistence of surface drying, following the monsoon season (June–September) rainfall deficit, as the key driver of the twenty-first century hot extremes. In correspondence to a nationwide warming of 0.5 °C since 2001, the hot days (HD) frequency have dramatically risen by ~ 60%. This has contributed to an accelerated summer warming of 0.28 °C per decade, two times faster than the annual average temperature. Strong coupling at the daily and seasonal scales provides useful predictive information about the summer heating process. We particularly illustrate how local feedbacks, in the backdrop of blocking anticyclones, played an important role in the evolution and amplification of India’s hottest and second-hottest summers during the 2009/2010 and 2015/2016 hydrological years, respectively. Under cyclonic conditions, in turn, a weakened feedback produced the coolest summer in 2011. Meteorological characteristics of the 2010 record-breaking event in India, reflected through HD and heat wave duration (HWD), are comparable at the global scale. But it’s difference with respect to lethality helped us to explore the nuances of deadly heatwaves, particularly their unique location specificity. Our study suggests surface drying under unabated anthropogenic global warming may accelerate feedback processes, unfolding new challenges with widespread socioeconomic impacts, in absence of precautionary policy measures. | en_US |
