The week it was hot

And continued to be hot. And still is hot.

Wearing bathers around the house, sleeping in the living room under the fan, covering windows with wet towels, giving up on the balcony plants, staying at work until late because that’s where the AC is, eating watermelon for dinner kind of hot.

A heatwave is currently gripping Europe with its sweaty paws, breaking records all over the place and driving people to the beach in massive numbers. Helpful timing for the Our Common Future Under Climate Change conference happening in Paris right now.

The temperature in Tortosa has not dropped below 20º since the 26th of June, and maximum temperatures are ranging between 30 and 39ºC. It’s these high minimum temperatures that can be the real killer, particularly for the elderly and vulnerable who do not have access to AC.

I was going to try and write about the science of this crazy heat, but a) my computer (and myself) do not work well in high temperatures and b) this article from The Conversation explains what is going on, with neat pictures too.

Essentially a high-pressure system has parked itself over western Europe, suppressing clouds and diverting any low pressure system that might want to meander this way. It is also being fed warm air from the south thanks to high pressure in the upper parts of the atmosphere. Just read the article, they explain it much better.

In Australia, heatwaves occur in a similar way, when the jet stream and a surface high pressure system push warm air down from the middle of the country. However in Europe, the warm air comes up from Africa, instead of down from the red centre.

One interesting part of that article that I was not aware of is the Spanish Plume. The warm air travels up from Africa, over the Iberian Peninsula where it gets even hotter and drier. From there it ends up near the UK, where it meets cooler air coming down from the north. This results in some terrific thunderstorms.

We were lucky enough to experience both the middle and the edge of the giant pillow of hot air this week. For the first half of the week we melted in our non-air-conditioned apartment, eating ice cream and trying to think of cold things.

In the second half we were in Ireland for the wedding of some lovely friends. I’ve never been so happy to wear a scarf! Western Ireland was brisk and showery, which may be characteristic of the Atlantic climate, and on our return to Dublin we saw some ripper cumulonimbus clouds which I now realise may have been the edge of the warm air. We even went through a town that had completely lost power thanks to the storms.

Now we are back in the heat, daydreaming about green fields and trying to keep cool. There is no respite in sight, with the Spanish Meteorological Agency predicting similar temperatures for at least the next week. Please look after yourself Tortosins, and your neighbours. See you at the beach.
