Weather: And now we really fear the return of the year without the summer. Let’s find out what “a year without a summer” means.

Thermal anomaly of 1816, the year without a summer The year without summer wouldn’t be new, it really is! We are trying to explain to you what “a year without a summer” means by taking a short time excursion.
Also known as the year of poverty, That was 1816during which severe summer anomalies destroyed crops in northern Europe, the northeastern states of the United States, and eastern Canada.
Today it is believed that those climatic anomalies were caused by itTambora volcano eruption, on an island Sumbawa from the current IndonesiaAnd held from 5 to 15 April 1815, A volcanic eruption released large amounts of volcanic ash into the upper atmosphere. As is common in the aftermath of large volcanic eruptions, global temperatures dropped as sunlight struggled to pass through the atmosphere.
This was superimposed on two other important phenomena of the period: rhombus minimum, During which it is believed that the sun gave less energy and the so-called Little Ice Age (still in progress at the time), or a phase of general cooling of the planet that lasted from the Middle Ages until 1850.

Don’t worry, there are no eruptions going on, the sun is still doing fine and we’re clearly not in an ice age!
But beware: it rains almost every day and it’s also cold! But what is happening at the hemisphere level? And above all: Will there be sequels next summer, too? To understand what to expect, you should, as usual, analyze seasonal maps that give us an overview of the expected precipitation and temperatures for the coming months.
Furthermore, we need to broaden our view of the entire global climate system, with a particular focus on what will happen in the central Pacific.

Two important events alternate in this area: Nina And El Nino: These are large-scale phenomena, observed on the surface of the equatorial, central and eastern Pacific Ocean and capable of influencing global climatic conditions, respectively. Abnormal heating And Abnormal cooling.
The names of these two phenomena, seemingly a little funny, are easily explained El Nino this means “Child” In the Spanish language, in fact, the thermal anomaly generally reaches its peak around the Christmas period, or precisely the period of the birth of the Child Jesus. The audio is in Spanish because it affects the Spanish-speaking regions after the Colombian colonization. La Niña It is nothing but the opposite of El Niño.
Thus, it is respectively cooling and warming of the ocean surface. during a loop of Nina water resulting from 1/3°C cooler, while in stages Nino I am from 1/3 degree Celsius hotter As a result, global average temperatures also tend to increase

Meanwhile, what we do know is that NOAA, the US agency that deals with ocean and atmospheric dynamics, has just announced that the surface waters of the Pacific Ocean are warming beyond expectations, triggering the phenomenon known as El Niño is expected to be great this year.
Although El Niño generally leads to global warming, For now, the Mediterranean summer is limping And not a bit, in complete contrast to the global warming trend that has been highlighted for some time.
In the coming weeks we will see if the configuration changes or not.
