1. A tropical cyclone is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rain. Tropical cyclones feed on heat released when moist air rises, resulting in condensation of water vapor contained in the moist air

2. OCEAN BASIN	SEASON	AVERAGE CYCLONES PER SEASON (winds above 63 km/h)	PERCENTAGE OF GLOBAL TOTAL	SEVERE CYCLONES PER SEASON (winds above 120 km/h)
   North Indian	May to June & October to December	5.4	7%	2.5
   Northwest Pacific	Mainly June to December	25.7	31%	16.0
   Northeast Pacific	May to November	16.5	20%	8.9
   North Atlantic	June to November	9.7	11%	5.4
   Southwest Indian	December to April	10.4	12%	4.4
   Southeast Indian/Aust	December to April	6.9	8%	3.4
   Southwest Pacific	November to April	9.0	11%	4.3

3. Queensland
4. 10
5. Typhoons, Hurricanes
6. Tropical cyclones develop in the Tropical regions of the world. Heat from the sun causes warm,High 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. If the air pressure in the upper atmosphere is Moist , 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. Is the centre of the storm and it is calm and has clear eyes
8. 
9. If they arn't intense enough

2.4

1. Is when water rises An overflowing of a large amount of water beyond its normal confines Cover or submerge (a place or area) with water
2. Flash flooding associated with severe storms is relatively common in Australia. Small rivers and streams are unable to cope with the sudden volume of water caused by heavy downpours so flooding results. This happens in urban areas as well when drainage systems become overloaded, resulting in flooding. The duration of flash floods is usually hours. Urban areas are at risk because in urban areas there are just small drains that can easily get blocked making a flood
3. The coastal rivers run fast so Flash flood are fast and last for longer while the inland one there is more damage but there is a earlier warning
4. Powerlines damaged, railroads damaged, Buildings damaged
5. More water fell which made the catchment already saturated and the 1998 flood was 20,3 meters not 19 meters as the 2006 flood was
6. Economic: Loss of buildings and small buisnesses Social: loss of lives, Enviromental: lots animals dead

2.3

1. hail with a diameter of 2 centimetres or more wind gusts of 90 kilometres per hour or more flash flooding tornadoes.
2. Lightning
3. The atmospheric conditions that cause severe storms typically develop when warm humid air is pushed upward into the atmosphere by converging surface winds. As the air rises the moisture condenses releasing heat energy called latent heat into the air. It causes the air to become more buoyant allowing it to rise further into the atmosphere, up to a height of 12 kilometres. The water freezes forming ice crystals and potentially hail
4. Latent heat refers to the heat that is released into the air when the moisture condenses. It makes the air more buoyant and it rises further with that buoyancy
5. 12 Kilometers in the Air
6. Where the air goes in and out because it starts spinning around and around going faster and faster
7. The Bureau of Meteorology, Mainly if they have already struck and where they are headed to.
8. Because they can form fast and unoticed.
