A team of researchers from the Instituto Dom Luiz (IDL), the Instituto de Geociências de Madrid and the Universidad Complutense de Madrid analyzed the evolution of Saharan air intrusions during the summer in the Iberian Peninsula. The authors, including the researchers of IDL Pedro Sousa, Ricardo Trigo, and Alexandre Ramos, used data records since 1948 and found that intrusions of Sahara air masses increased in frequency during this period, particularly since the mid-1970s. According to this study that has just been published on Weather and Climate Extremes journal, these intrusions, which are often associated with heatwaves, reach latitudes further north in the European region. Therefore, this work shows the increasing frequency and severity of one of the main mechanisms responsible for the occurrence of heatwaves, a phenomenon that has significant impacts on public health, forest fires or drought management.
