State Meteorological Agency (AEMET)

The State Meteorological Agency (AEMET) has issued an information note warning of "exceptionally high" temperatures for this time of year in Spain, especially between Friday 29 September and Monday 2 October.

A model-based study estimates that there will be ice-free Arctic Septembers about a decade earlier than previously predicted. The possibility of this happening between 2030 and 2050 exists even in low-emissions scenarios, which is a more pessimistic estimate than the last IPCC report. The results are published in the journal Nature Communications.

The State Meteorological Agency (AEMET) has reported that, from Tuesday, the progressive entry of a mass of very warm and dry air of African origin over the peninsula and the Balearic Islands will cause exceptionally high temperatures for this time of year, with values typical of summer. According to AEMET, during Thursday 27, the threshold of 30 ºC is likely to be exceeded throughout the southern half, as well as on the banks of the Ebro. On the other hand, 35 ºC is likely to extend to the Guadalquivir valley in Córdoba and Jaén. During Friday it is possible that 35 ºC will be exceeded in the banks of the Ebro in Zaragoza and other points of the southern half, in addition to the Guadalquivir valley, where the maximum temperature values could be around 38-40 ºC.

Spain is suffering these days a new heat wave that, according to experts, will last at least until Monday and it is not clear when it will end.

A study published in Nature Geoscience shows how climate change is interfering with processes affecting atmospheric circulation and significantly altering the climate in Spain and Portugal. The anomalous expansion of the Azores anticyclone is drying out the Iberian Peninsula and making it increasingly resemble North Africa.
