1) If the air pressure in the upper atmosphere is relatively high it will limit the altitude that the warm, moist air can rise to. This high pressure causes the rising air to spiral outwards thus forming a tropical cyclone.
2) They form in the tropic of Capricorn throughout November through April.
3) The most areas that are at risk in Australia are Queensland and the Northern Territory.
4) 6 are likely to cross the Australia’s coastline per year.
5) The other names for tropical cyclones are Typhoons and Hurricanes.
6) Tropical cyclones develop in the tropical regions of the world. Heat from the sun causes warm, moist air to rise into the atmosphere. As the air rises, a low pressure system forms and condensation occurs, which releases latent heat causing the air to rise further into the atmosphere is high, then the rising column of warm air will spiral outwards in the upper atmosphere and air will rush from the surface to replace it, forming a tropical cyclone.
7) The eye of a tropical cyclone is the middle where there is a pipe-like hollow centre.
8)
9) The tropical cyclone is downgraded to a tropical storm when it moves to cooler water and loses its energy supply of warm, moist air.
