These days, the British press has started running headlines about the dangers of drought that are beginning to occur in the country. It reminds us of the situation we experienced just a month ago in our country. Three weeks of atmospheric dipoles temporarily changed the meteorological reality of Western Europe. A powerful anticyclone settled in the latitudes of the British Isles and at the moment does not want to move. It is the kind that favors the condition of rains and storms in Spain because, by contrast, in southern Europe and northern Africa, the cold air in the middle and upper layers of the atmosphere has caused frequent unstable conditions. This is bipolar. Abnormally high pressures are located at high latitudes, and low pressures dominate our pressures. When the usual thing is the opposite: Atlantic storms swirl over the UK and atmospheric stability and anticyclones are here. In the UK, a week of anti-cyclone causes drought alert. Let’s not say three weeks as already recorded for this anomalous spring of 2023. Models for the coming weeks indicate that this pattern of atmospheric circulation will continue for at least the first half of June. In Spain, these rains recorded since mid-May turned out to be fantastic. They cannot solve the drought that exists in many regions, but they allow the specter of water limitations in agriculture and the urban environment to disappear for weeks. They irrigate the fields, wet the soil, and reduce evaporation. They hardly contribute to the water reserves of the reservoirs, due to their local character and density. But if this does not happen, we are now talking about applying more serious water restriction measures to irrigate large areas of the Mediterranean coast, in addition to those already applied in Catalonia and Andalusia. So the current dry conditions in the UK favor us here. They allow the formation of unstable conditions. It’s what the atmospheric dipole pattern has been fixing on the North Atlantic synoptic landscape in recent weeks. And that, for now, he doesn’t want to move.
