How the sea affects the climate!

We often see the sea as a blue horizon framing coastal locations but, in reality, it holds a submerged world, and not, waiting to be discovered. For example, what is wave motion caused by? Certainly by the wind, but also indirectly by changes in atmospheric pressure over long stretches of sea. A strong, constant wind that blows for hours can cause long waves to develop with an average frequency of 10 seconds between one and the next; a centre of low atmospheric pressure that moves over the sea can cause violent swells because, in addition to the synoptic wind, the wind of the vortex’s translation is also added. Another fundamental factor is the temperature: the sea transfers heat to the atmosphere and water vapour gives rise to disturbances. In recent years, the +1.5 degree increase in sea temperatures is not only causing serious impacts on marine biodiversity but also has consequences for what happens in the atmosphere, where weather phenomena occur. This increase in heat transfer contributes to increased energy in the free atmosphere, which violently discharges the surplus onto the land with heavy rainfall and strong winds. This is how meteorological phenomena can become more violent and cause so-called Medicane. To save the earth and the seas we need to stop climate change otherwise, with the emission of climate-altering gases, the temperature is bound to rise and the risk of more violent weather phenomena on our territory, already extremely fragile and vulnerable, is very high.   
Did you know… The Medicane
It is the union of the words Mediterranean and Hurricane, “Mediterranean hurricane”. It is a tropical cyclone of the Mediterranean very similar to those occurring in the oceans. It is characterised by a low-pressure system with a warm core where winds and torrential rain rotate.
