Weather: SUMMER is already real, the latest news for the months of July and August!
Season projections for next summerAfter an unusual winter, characterized almost entirely by anything but cold temperatures and the prevailing drought, spring was quite dynamic, cool and stormy.
With these premises, what summer should we expect? Will it really be the hottest ever?
Well the seasonal forecasts just came out and the maps are amazing.
According to the latest updates, the summer that has just begun is likely to be characterized by well above average temperatures between +1.5°C and +2°C For July in most of Europe, including Italy.
Analyzing the following map, the thermal anomaly in practically all of southern Europe, in particular in the Mediterranean basin, is immediately striking, probably due to greater interference from the infamous african anticyclone. Until 10-15 years ago, the milder high pressure of the Azores (of oceanic origin) dictated the law on the Old Continent. Lately, however, we have been witnessing increasing interference from air masses coming from North Africa, responsible for the stronger and more persistent heat waves even in our country.
Temperatures above the climatic average between June and July (source: ECMWF)It is therefore a first concern for the beginning of summer (July), also in line with recent years, in which the problem of climate change is becoming increasingly evident and pressing, also in our country. Recent studies confirm that among the effects of climate change we also find an increase in the frequency of Heat waves. To make the heat even more unbearable are the high levels of humidity (embarrassment) and the reason is all geographical: in fact, the hot air masses that arrive from the African continent are enriched in humidity as they pass through our seas and this will affect the humidity indicescausing a increased physical discomfort.
Among the effects of this changing climate (towards the heat) the risk of extreme weather events. With heat, the potential energy involved also increases and, above all, thermal contrasts are especially enhanced, creating a lethal mixture for the development of imposing storm cells, even up to 10/15 km high. In fact, it happens that after a heat wave in the lower layers of the atmosphere, large amounts of moisture and heat stagnate. Subsequently, with the first cool and unstable gust at high altitude (usually downhill from northern Europe), convective movements (rising of hot air) favor the genesis of violent storms, with high risk of hail and in some cases, fortunately rarer, even of tornadoes.
Finally, taking a look at the very long term projections, it really looks like we will have to deal with very high and above average thermal values for the month of August.
However, we will talk about all this again.
