The scientists had not yet arrived at a conclusion on the increase of the frequency and the intensity of
hurricanes, but they know that the cyclones of today are more powerful of what of the past, and that the
temperature of the water in the surface of the oceans went up throughout the years.
“The belief Exists of that this change of intensity directly is associated with the change in the temperature of the sea”, Carlos Hoyos said, Columbian scientist of the Institute of Technology of the Geórgia.
The divergences start exactly there, therefore one has left of the scientific community makes responsible the human being and believes that the global heating, provoked for the emissions of carbon dioxide, raised the temperature in the seas.
Another group affirms that the heating in the surface of the seas is part of a natural cycle. Segundo Hoyos, all agree that the
biggest level of activity of hurricanes “goes to continue at least during the next decade”.
The biggest
cyclone of the last season was the Katrina, that arrasou
New Orleans and caused damages of the US$ order 80 billion.
However, this
Hurricane was not an isolated case, since it duplicated the cyclone
number that had reached categories four and five (the greaters in the Saffir-Simpson scale) in last the 35 years, as a study carried through for the team of Hoyos.
In 2005, 28 tropical storms in the Atlantic had happened, being that four of them had turned hurricanes category five, a new record.
The Mexican Martin Medina-Elizalde, of the University of California, explained that the hurricane number will not increase in the next years, however they will be stronger. The reason of this that the cyclones count on a nucleus moved for the hot water, is considered its fuel.
