The problem of heat arrival is not just the 40º planned by Aemet: also the “tropical nights”

Heat has come and with him a more annoying phenomenon than the high daytime temperatures: the so -called “tropical nights.” Bad news for those who have problems reconciling with heat.

Tropical nights. The warm episode that this week is manifested on a good part of Spain threatens to bring maximum thermometers above 35º in various areas, even above 40º in areas such as the Guadalquivir Valley. However, beyond the maximum, There is another fact to pay attention: minimum temperatures.

We talk about “Tropical nights“When the minimum night temperatures do not fall from the 20th Celsius. That will be precisely what happens in areas of the southern peninsula and in the Canary Islands throughout the week, according to the forecasts of the State Meteorology Agency (Aemet).

According to Aemet In an informative note Dedicated to the warm episode, the minimum temperatures will rise throughout the week, more slowly and intense than the maximum, yes. The minimums above 20º will affect areas of the southwest quadrant and the Mediterranean coast, also extending to the Ebro Valley during Saturday.

On the edge of the “equatorial night.” In fact, Aemet’s forecasts They anticipate minimums that could remain around 24th towards the end of the week in areas of Malaga or Cádiz. This implies that some areas are on the edge of the call “Equatorial Night”, Term that refers to the nights on which the minimums do not fall from the 25th.

A anticyclone, and a Dana? But what is happening so that spring has ended so abruptly? Much of the fault has an anticyclone inside located on the waters of the Atlantic, around the Azores. The influence of high pressures will leave us a great atmospheric stability, explains Aemet, with “practically clear skies and high insolation.”

But there is even more: from Wednesday, the appearance of a Dana between the Canary Islands and the Gulf

From Cádiz I could drag with it a mass of warm, dry and with suspension dust, first to the south and then towards the peninsular center. The result of this would be the additional increase in the temperatures that we will see throughout the second half of the week.

Notices for extreme temperatures. Thus, the agency has issued several notices for extreme temperatures for tomorrow Wednesday and for Thursday by maximum temperatures between 37º and 39º.

Is there an end in view? The big question now is when this will end. And the truth is that it is still early to venture since uncertainty predominates towards the end of the week, says Aemet. According to Explain the agencyit is “likely that as of Saturday 31 the Dana will dissipate” and that instability in the peninsular northern increases, in turn giving clouds to reduce the failure of these days. In any case, we will have to wait to see if these predictions are confirmed.
