They are known as Hurricanes in the Caribbean, Typhoons in the China Sea, Cyclones in the Indian Ocean and most commonly called Tropical Cyclones. You can call them what you want but they all have one thing in common: they are extremely destructive when they hit cities and towns.
A cyclone is a huge mass of air moving in a spiral with winds that can reach up to 250 km/h. A cyclone starts off in the sea where the winds are calm and the water temperature is at least 240. Warm air pushes upwards at a fast rate while cold air is sucked in below. The warm air gains moisture and starts producing thunderclouds. Spinning in a clockwise direction (anticlockwise in the Northern Hemisphere), the cyclone gradually picks up speed. Driven by the fast winds, the Cyclone can move at up to 50km/h. While all this is happenin
Although you can't change the path of a cyclone, there are ways of reducing it's impact. Systems for advanced warning are pretty advanced now and people now have time to prepare for cyclones. There are now satellites and radars so we can detect cyclones and accurately predict their course. There were no accurate warnings 50 years ago and people had to rely on sight and their barometers. Normally most people who die from a cyclone die from being at sea. So if a cyclone is coming, it's safest to stay indoors in a small room with the windows sealed shut and any debris outside put away in a safe place. The other thing that has changed is that when Darwin was rebuilt after the cyclone, they used new construction rules so that all of the new buildings are much stronger and more likely to survive very strong winds.
