The best news for the heat that will be this September is thousands of kilometers from Spain

In the midst of one of the most important droughts in recent memory in the northern hemisphere, with the heat refusing to go away and the Mediterranean maintaining devilishly high temperatures, several different phenomena make us harbor some optimism about returning from vacation. The global processes that are behind the arrival of winter have already begun and that is excellent news.

The arctic has started to cool down. According to the Danish Meteorological Institute, at 80º north latitude the temperature has started to collapse. It is not about anything abnormal: it is usual that from the second fortnight of August, as the sun stops heating that area of ​​the atmosphere, the polar vortex becomes increasingly powerful and gains ground in the northernmost part of the northern hemisphere.

However, this year we were not very clear when the process was going to start. We must not forget that the Baltic countries are experiencing a very harsh summer and until a few days ago 30 ºC were common. We were not clear how this anomaly could end up delaying winter throughout the hemisphere; but the first frosts in Greenland, arctic ice growth and the appearance of storms in Iceland portend that the tentacles of winter will begin to be felt throughout the European continent.

But that’s not the best news. The best news is that “the European model foresees a beginning of September in which low pressures will reign in Europe”. This means that, as Juanjo Villena points out, editor-in-chief of Meteored, “the military ride of the summer has come to an end.” If the surface heat continues as expected, “as soon as the temperatures in the upper layers of the troposphere drop and there is a minimum trigger mechanism, the storms will grow. The weather begins to scramble.”

The truth is that if September is rough, we cannot guarantee better temperatures (in fact, they are expected to remain above average for a few more weeks), but we can expect rain. And with the rains, perhaps we can improve our figures for stored water. Figures that, moreover, are at historic lows and anticipate a water season full of restrictions and problems.

Spain faces the driest climate in its last 1,200 years.  The fault lies with the Azores Islands

waiting for hurricanes. This is the latest phenomenon that seems to be underway: hurricanes. Although all the experts expected this season to be more active than normal in response to La Niña and unusually warm waters of the northern hemisphere, the truth is that (so far) is being much less active than expected. However, the main institutions they think it’s a matter of time and we begin to see signs that this is so. This is also a sign that we are heading towards winter.

We’re gonna need another lucky break. These are the main reasons to be optimistic this September and we are going to need it. What pointed out the latest bulletin of the World Meteorological OrganizationEverything indicates that ‘La Niña’, which began in September 2020, could continue, “very likely” until August and “possibly” until autumn or early winter in the northern hemisphere. It may even persist until 2023. And that means that the drought is going to continue with us. Hopefully winter will help us weather the storm.
