Violent wind storms are called cyclones in Australia, and are known as typhoons and hurricanes in other countries.Tropical cyclones begin over warm tropical seas in areas of low atmospheric pressure. The warm, moist air begins to spiral and becomes a strong, circling, wind storm. In the centre of a cyclone, there is a calm area called the 'eye'. In the eye, the sky is clear and there is only a light wind blowing.
Cyclones can change direction suddenly, which makes it very difficult for meteorologists to forecast what will happen. Tropical cyclones bring heavy rain and cause high waves.
Cyclones cause damage
Cyclones move at up to 360 kilometres per hour, bringing heavy rain. The wind and rain causes lots of damage when the cyclone crosses over coastal lands.
