Short summary
This study investigates the global drivers of sudden temperature changes from one day to the next using observational data and trajectory analysis. In extratropical regions, these shifts are mainly driven by air mass movements linked to circulation patterns. In tropical areas, local factors like cloud cover play a key role. Understanding these mechanisms improves predictions of extreme-temperature events, aiding in better preparation and mitigation strategies.
