intro
How a cyclone form in specific detail
Gently falling cool air in the eye
Rapidly rising warm moist air in the eye wall
Heat energy is released by condensation
Very strong winds and torrential rain
Less intense cloud wind and rain
Storm surge
And most cyclones goes to the west hemisphere and travel in warm water about 27 or more degrees celsius and the sun evaporate the water and then stream creates a form of a cloud and then the wind creates a tornado and then the cloud forms in to a “V” shape and them the air force goes faster and faster and then creates a cyclone
Very low pressure 1000 milla bars lowest 960 millibars.
The sea level increases on the land.the crops will be destroyed and just have a low amounts of crops. And the winds are a problem and having a warning system so people are warned. And ust protect as much as much as they can and be prepared. And having wall will decrease the force
They start around 15 degrees later and you don't know where they're gonna be and you don't know where the direction is coming from. And to get a cyclone is having warm water and circulates as a tornado. If having small cyclones only around 10 and the katrina cyclone has a 2000 death toll.

Storm surge
Torrential wind
Very strong winds
Floods
Water contamination
HUMAN RESPONSE
Locate buildings and transport away from danger zone
Physical protection against storm surges and floods
Property insurance
Emergency plans and disaster relief
Strict building codes
Constants surveillance and warning systems
None - accept the occasional loss of lives and damage to property
Surveillance
Scientists know when and where tropical cyclones are likely to occur because they get information from satellites, aircraft and people in tropical cyclone areas. If a tropical cyclone
All tropical cyclones start as cyclones, or depressions, these are small low pressure areas. As barometric pressure drops and wind speeds increase, these depressions develop into tropical storms. Tropical storms may turn into tropical cyclones, but only if a certain combination of factors is present
A large warm tropical ocean. ocean temperature must be at least 27 C. this heating occurs when the sun is overhead.
A low pressure are develops and warm moist air rises. The warm sea water evaporates, and moist air rises above the tropical ocean like steam from a kettle. It is replaced by surface air that is sucked into the growing cyclones
Cumulus clouds form a latent heat energy is released. As hot moist air is dragged upward, it cools and condenses. Towering cumulus clouds develop, and there are intense rainstorm, thunder and lightning. Latent
Key term:
Evaporation the process by which water droplets are warmed and turn back into gass
Cumulus clouds big puffy clouds that push up into the atmosphere; associated with rising warm air
Insolation solar heat energy (heat energy from the sun)
Away from the eye wall
Y As you move away from the eye wall in any direction, the air pressure, winds, rain and cloud cover become less intense. Long spiral bands of cloud develop on the outer edges of the hurricane to give the beautiful catherine wheel effect you see on satellite images
The ocean below
Pushed down by falling air in the eye of the hurricane
Sucked up by strong winds in the eye wall
The eye
The eye is a 10-15km-wide cylinder of clear air in the middle of a tropical cyclone cool,dry air drops through this tube to the earth's surface and then spreads out
The eye wall
The eye wall encircles the eye. It has towering wall clouds up to 15km high. Air pressures are extremely low in the eye wall and winds are strong- up to 320km/h. The winds spiral upwards around the eye and pull up warm, moist air rises, it cools; water vapour condenses and latent heat energy is released \. Torrential rain falls. When air in the wall cloud reaches the stratosphere, it spreads out like a giant umbrella
Top 10 most deadliest cyclones
The biggest cyclone that happened
Great bhola cyclone, bangladesh
Death toll: 500,000
About the cyclone that happened in bhola its been the biggest cyclone yet to ever happened in the world and in bangladesh. And this cyclone happened in november 11 1970. And the cyclone was destructive. It destroyed a lot of houses and killed half a million people that were in the cyclone and that was 500,000 people that died. And that cyclone remains to be the deadliest cyclone that has ever happened.
This is the information from the internet :
It remains the deadliest tropical cyclone ever recorded and one of the world's deadliest natural disasters. At least 500,000 people lost their lives in the storm, primarily as a result of the storm surge that flooded much of the low-lying islands of the Ganges Delta.

Damage to people
People are killed during a cyclone because of the wind force and the flying object caused by the cyclone. And the fly object might be bikes,tools,house material and other stuff. People can get injured very badly by these things. And the wind can destroy buildings and buildings and fall on people and the parts of the buildings can fall on people as well.
Damage to crops
Crops are destroyed by the flood caused by the cyclone. And the tough flood gusheshe through the crops and then wipes all the crops out. And after the cyclone has finished then there will maybe be a few standing as crops. And thats why we should put walls or gates around the crops so the wall/gates can reduce the force of the flood so it can not go as fast and as big.
Damage to floodings
Flooding can cause buildings to fall down because of the force of the flood and how fast it comes to land. And the floodings can cause death,destroying buildings and more. Floodings can wipe anything that cames its way like people etc. floodings can fill up the roads and houses. And floodings can cause power cuts.
Solution 1
Warning siren:
Warning sirens are things we need for cyclones because people can be warn for the cyclone that is coming and sirens warn people to seek shelter. And that gives people time to evacuate to the safest places they can find and seek shelter. And warning sirens can warn people at the beaches as well e.g if people were still swimming at the beaches and people surfing at the beaches
Solution 2
Predicting where they will happen…
Tropical cyclones also occur in various parts of the Pacific Ocean, and can affect coastal regions of Mexico, southeast Asia, northeast Australia and the south Pacific islands.
