Observation of marine sleeves and Tornadoes in the Mediterranean (for example, Barcelona, Alicante or the Balearic Islands), but also in Italy and other nearby areas. But is this really due to a real increase in the frequency of these phenomena, or is it simply the result of the greater diffusion allowed by social networks and increasingly sensitive meteorological tools?
To get started, you should know that hoses and marine hoses are not exactly the sameeven though they really look like it. What they have in common is that they have a rotating column of air and both eddy and hurricane winds. The only real difference between a hurricane and a hurricane is the storm that gave birth to it.
Hurricanes are one of nature’s most destructive phenomena.storm clouds arise from the base of the cumulonimbus and can produce winds of up to 500 km/h, can last for hours and travel hundreds of kilometers, the most extreme form in the USA but also in Australia, New Zealand, Canada, the United Kingdom and Mexico.
in Spain We have evidence of hurricanes, some of them quite devastating, but occurring in desolate areas. They generally have widths between 90 and 600 meters.
The rotation on the ground is cyclonic, like the movement of children’s tops, and they suck in the air in the environment, picking up everything that comes in their way. This is why we often see them as dark because of the dirt and bits of houses or fences they find in their path. They move with the movement of the cloud, explains the portal eltiempo.es.
Instead, water hoses are normally associated with the cumulus ‘congestus’.They form over lakes and oceans, but they also form at the base of large Cumulonimbus clouds. They are normally 450 meters high but can reach up to 900 meters, being isolated or grouped, the sign of their formation is sometimes the shadow on the water of the swirling air. They draw curved paths that can take up to 15 minutes.
Hurricanes and climate change: What is the relationship?
Now, when we talk about hoses and water hoses, what is the relationship between these phenomena and climate change? Why is its presence in the Mediterranean increasing?
To answer this question, go to: most the laws of thermodynamics, they tell us that An important parameter for the development of a hurricane is sea surface temperature..
The reason for this is a warmer sea provides more energy to a hurricane, making it particularly violent.
As long as these hoses stay in the sea or in non-densely populated areas, it’s fine. But when these phenomena touch the ground through residential areas, cities or major industrial centers, we find ourselves in very serious damage and sometimes tragedies, says meteorologist Daniele Ingemi.
A new scientific article published in the international journal Scientific ReportsIt explains exactly why a warmer-than-normal sea (that is, with a higher temperature than the climatological average) can stimulate these phenomena, such as those observed recently in southern Sicily.
In this study, the authors take as an example the tornado that hit the port area of Taranto, Italy, and the ILVA facility on November 28, 2012, causing one death and 60m euros in damage.
During this hurricane event, The temperature of the Ionian Sea was approximately +1 °C above the climatological average of the period. (this is a very recent average, since it refers to the two decades between 1985 and 2005, and thus relates to a period when global warming had already advanced), Ingemi adds.
The warmer the sea, the more tornadoes occur.
Using sea temperature data, they applied a high-resolution weather model (about 1 km of grid). can accurately reproduce the trajectory of the supercell this led to the hurricane Taranto.
The same authors conducted another simulation with the same exact model, but this time using sea temperatures as a reference, with values close to the climatological mean for the period.
This latest simulation only showed what the sea temperature was like. -1°C (so on average), the famous supercell would not have formed and as a result the hurricane would not have developed. On the contrary, by increasing the temperature +1°C the hurricane would be even more violent.
In the research, in which researchers such as Mario Marcello Miglietta, Jordi Mazon, Vincenzo Motola and Antonello Pasini participated, He underlined that the Mediterranean is becoming an increasingly frequent scene of such acts of violence.
The faster increase in density when a certain temperature value is exceeded is called by its inevitable reflections in our regions.
Numerous Spanish experts have confirmed the gradual warming of the waters of the Spanish Mediterranean, which only facilitates the conditions for the emergence of hurricanes.
