FAQs about Hurricanes

4. What is a hurricane?

A hurricane is a cyclone or wind of great force that forms a whirlwind and turns in large circles. For a cyclone to be classified as a hurricane it must at least have a rotation speed of 119 km/h or 74 mps. A hurricane originates in the tropics and since its formation begins to expand its diameter and speed, generally following this cycle: tropical depression, with a speed less than 63 km/h or 39 mph < tropical storm (64 km/h or 40 mph) < hurricane, with a speed equal to or greater than (74 – km/h or 39 mph). Hurricanes are measured according to their speed and the damage caused, generally using the following scale: The five categories of the Saffir-Simpson wind scale: Category 1: 119-153 km/h – 74-95 mph / No damage to building structures Category 2: 154-177 km/h – 96-110 mph / Damage to roofs, doors and windows Category 3: 178-209 km/h – 111-130 mph / Structural damage in small buildings Category 4: 210-249 km/h – 131- 155 mph / Generalized damage to protective structures Category 5: 250+ km/h – 156+ mph / Complete roof destruction in some buildings.

What are hurricanes and how do they relate to global warming

There are mixed views on the relationship between global warming and hurricanes. So far, no evidence has been found to support this relationship. Whenever there is an extraordinary phenomenon that is supposed to be related to climate change, a precedent occurs, often 50, 100 or more years ago, when global warming, the main factor in climate change, was not a issue. However, with the recent Hurricane Irma (Sep-2017), there was a fact that had never happened. For the first time a cyclone acquired category 5 in the Atlantic Ocean, before reaching the Caribbean…

A hurricane usually originates in the tropics and since its formation, in most cases, begins to expand its diameter and speed. Hurricanes are classified according to the Saffir Simpson wind scale, in five categories, mainly according to their speed…
