Does the meteorological origin of heat waves influence their impact on health? A 6-year morbidity and mortality study in Madrid (Spain)

In Spain, two synoptic-scale conditions influence heat wave formation. The first involves advection of warm and dry air masses carrying dust of Saharan origin. Objective: to determine whether the impact of heat waves on health outcomes in Madrid (Spain) during 2013–2018 varied by synoptic-scale condition.The authors wish to thank the funding provided by the ENPY 304/20, and ENPY 436/21 projects of the National Health Institute Carlos III (ISCIII)
