The year 2020 never ceases to amaze. After everything that has happened so far, it must be added that, for the second time in history, they have been detected five simultaneously active tropical cyclones in the Atlantic Ocean. The last time something like this happened was in 1971, almost 50 years ago.
The U.S. National Hurricane Center (NHC) has reported that Hurricane Sally, Hurricane Paulette, Tropical storms Teddy and Vicky, along with tropical depression Rene (which will disappear in the next few hours) have reunited in the Atlantic Ocean.
The scientific explanation for this phenomenon is not simple. “You have to be clear: there is no single answer to this phenomenon. What we see here is the sum of many factors that coincide to produce these five tropical storms at the same time, “British Weather Services meteorologist Jim Dale told the BBC, according pick up the CNN.
One of the factors to which this unusual event is attributed is global warming, however the meteorologist Dale does not fully agree: “This phenomenon also occurred in 1971, when global warming was barely being noticed, so we must always take into account the other elements that are part of the formation of hurricanes “.
There are several meteorological events that affect this union of hurricanes and storms. “Water heating, low pressure areas in warm waters, the direction of the winds, the absorption of hot and cold winds that give it speed, among others, “says Dale.
However, the expert points to two factors as the main causes: “The influence of ‘La Niña’, the current in the Pacific and, of course, the increase in ocean temperatures, which affected some areas of the Atlantic Ocean, especially on the West coast of Africa where most of these cyclones originate, they could influence this historical phenomenon “, he declares.
But global warming is also an aspect to consider, since Dale points out that, for example, “fires are now much more aggressive due to drought and rising temperatures.” In addition, he points out that it can be extrapolated to other phenomena: “With hurricanes something similar happens: we have known them forever, but the climatic effects that the Earth has suffered in recent years will cause that come up more often and in unusual situations like the one we are seeing. “
Finally, the five cyclones that currently exist can go in several directions, the most worrying are towards the United States and its coasts, as well as towards the Caribbean islands. According to the NHC, the passage of Hurricane Paulette through the Bahamas “It can endanger people’s lives.”
