The extent of heat waves increases by 4% per decade in Spain

The average extent of heat waves has increased by 4% per decade since 1950 in almost all of Spain, specifically in the Iberian Peninsula and the Balearic Islands, according to a study carried out by researchers at the University of Santiago de Compostela (USC) and the University of Vigo ( UVigo).

Alejandro Díaz-Poso and Dominic Royé (USC) have just published, together with Nieves Lorenzo (UVigo), the results of this study that shows how trends in the period 1950-2020 indicate that heat waves in the Iberian Peninsula and the Balearic Islands “ They are becoming more intense and extreme events are increasing in magnitude.”

Specifically, the highest intensities are observed in the west of the peninsula and mountainous areas, and the lowest in the Mediterranean coast. Likewise, the increase in the duration of heat waves is most pronounced in the east-southeast, USC said in a statement.

Research published in Environmental Research shows that the average extent of heat waves for the period 1950-2020 increased by 4% per decade, while the increase in maximum extent is even greater, 4.1% per ten years.

These results suggest “increased human exposure, increased energy demand, and implications for fire risk.”

The USC and UVigo team decided to carry out this study in the absence of climatological analyzes of heat waves for the Iberian Peninsula and Balearic Islands that use the EHF index (Excess Heat Factor), developed by Australian scientists, which directly incorporates the aspect of intensity and the acclimatization process of the human body.

Higher intensity does not mean longer duration.

The areas with the highest intensity of heat waves do not coincide with areas where these events last longer.

Both for the period 1950-2020, and for the specific case of 2018, the heat waves in the mountainous areas and west of the peninsula are characterized by a higher EHF, but of a shorter duration than those in the southeast of the peninsula and, in general, on the Mediterranean coast.

“The main reason for this spatial pattern lies in the rapid transport of soft air masses from the Atlantic Ocean to the west of the Iberian Peninsula”, explain the researchers.
