Correction to: Communications Earth and Environment https://doi.org/10.1038/s43247-023-00897-0, published online 06 July 2023.

In the original version of this article, the acronym “TD” was not defined. This has now been corrected: the original sentence “The Indian Meteorological Department’s heat wave definition and thresholds were primarily based on dry-bulb temperature19, although recent bulletins also provide relative humidity and wind speed.” has been corrected to now read “The Indian Meteorological Department’s heat wave definition and thresholds were primarily based on dry-bulb temperature (TD)19, although recent bulletins also provide relative humidity and wind speed.” This has been corrected in both the PDF and HTML versions of the Article.
