Is it normal to record these temperatures at this time of year?
"The extreme events we are seeing are not only becoming more frequent and intense, but are even arriving earlier than normal. This episode is not normal when we see anomalies of up to 10 degrees above average temperatures for this time of year, especially when we look at the maximum temperatures of 40ºC; these are temperatures typical of July, in the middle of summer. We are also seeing that the intermediate seasons (spring and autumn) are becoming shorter and the change is more sudden and abrupt.‘
And is it normal for it to affect so many areas of Spain?
’It is a combination of a mass of warm air from North Africa and a persistent anticyclone that is blocking the entry of cooler air. It is a synoptic-scale situation, so it can affect a large part of the peninsula. However, it is not only the warm air from Africa, but also the peninsula itself, which facilitates the warming of the air descending from higher layers (air descending in the centre of the anticyclone is compressed and heated adiabatically).
What recommendations would you make to the population, which only a few days ago was experiencing cooler than normal temperatures?
‘We know that the first heatwave and the first days of extreme heat carry a higher risk of mortality, due to a lack of seasonal acclimatisation. Therefore, vulnerable groups (the elderly, children, people with medical conditions) should stay informed, review and adapt their habits, reduce sudden exposure to high temperatures and anticipate changes.’
