США и Мексике грозит смертельная угроза, - ученыеRising air temperatures and surface water, affects the behavior typical of the Atlantic and Pacific cyclones

Global warming has sharply reduced the speed of movement of hurricanes in the Atlantic and Pacific oceans, making them more dangerous for nature and humans, say U.S. scientists from the Center for weather and climate NOAA in Madison.

“The main conclusion of our work, the speed of movement of tropical cyclones over water and land decreased by 20% in the Atlantic by 30% in the North-West Pacific and 19% in the coast of Australia. As a result, increased rainfall and floods have become more extreme. All this is extremely dangerous for people,” said James Kossin.

In their study, Kassin came to the conclusion that the increase of air temperatures and surface water, affects the behavior typical of the Atlantic and Pacific cyclones. This is what led to the fact that last year there was just four of the most powerful hurricane of the fourth category of danger: Harvey, Irma, Jose, and Maria, who created the disastrous situation on the Atlantic coast of the United States and Mexico.

Scientist have followed the dynamics of hurricanes in the Pacific and Atlantic oceans, and noticed that the speed gradually decreases as you move from the past to the present and, in General, decreased by 10% in all the Earth.

According to Cossina even so, it would seem, is not a strong reduction in the rate of storms may lead to catastrophic consequences for the population. If rainfall is doubled, the probability of occurrence of floods multiplies.
Besides, if a hurricane often changes the movement of “flight”, then it is likely that he will return to the shores again. Thus, if the average temperature will rise by 1.5 – 3 degrees, hurricanes will become more destructive for humanity.
