Typhoon Hyan Hurricane Case Study Flashcards
What are the main parts of a tropical storm?
the rainbands, the eye, and the eyewall.
How is tropical storm formed?
- water must be 27°C or above.
- Water vapour rises into the athmosphere.
3.As the warm water evaporates, it cools and condenses into liquid droplets.
4.Condensation releases heat into athmosphere making the air lighter.
- High humidity in the atmosphere.
6.thunderstorms to start the storm.
7.Coriolis Effect - The rotation of the Earth causes the storm to spin, which helps it to become stronger.
When did Typhoon Hayan hit the Philppines
7 November 2013
How strong was typhoon hayan
Category 5 super typhoon
How many people died in Typhoon Haiyan
6300
As well as the storm surge, what were the other primary effects of typhoon Haiyan
. Heavy wind damaging the infrastructure
.Heavy rain over (400mm) causing flooding
How long was the power out in some places after typhoon haiyan
Up to a month
How did Typhoon Haiyan affect the health?
Disease Outbreaks
Mental Health Issues
Malnutrition and Hunger
Spread of Infections
There were major shortages of food.
What other effects did flooding have after Typhoon Haiyan
Triggered landslides which blocked roads
Where r typhoons found in
In South China Sea and west Pacific ocean
Where r hurricanes found
In the gulf of Mexico, Caribbean Sea and West Coast of Mexico
Where r cyclones found
In the bay of bangalore,Indian ocean and northern Australia
Prediction for tropical storms
Scientist can use monitor storms using satellites, planes and innovation like radar
Metereologist buold models to try forecast the weather and cyclone
protection for tropical storms
buildings built safely and only in areas that are unlikely to be flooded or damaged by hurricanes.
Stilts are used in some nations to help stop flooding.
Reinforced concrete is a stronger material that is better protected against tropical storms.
Flood defenses can be constructed in vulnerable areas.
Planning for tropical storms
Special plans for evacuation and rescue could save lives.
Firefighters and ambulances should receive specific disaster training.
What’s low pressure zone
Warm air rises, causing low pressure
weather in low pressure
Wet and cloudy because rising air cools, forming clouds and rain.
e.g Heavy rain in tropical rainforests.
60° north/south: Stormy weather where warm and cold air meet.
What are High-Pressure Zones
Air sinks, causing high pressure
Protection from tropical storms
Building houses and buildings in areas that are unlikely to he flooded or damaged by hurricanes
Where is polar cell found
Near the poles
What happens in Hadley cell
Warm air rises at the equator, creating low pressure . It cooler and sinks around 30⁰ northland South of the equator, creating high pressure
What does the Hadley cell create
Rainforest at the equator (low pressure,lots of rain)
Deserts around 30⁰ (high pressure dry air)
What happens in ferrel cell
Air moves from high pressure at 30⁰ (sinking air) to low pressure at 60⁰ (rising air), creating westerly winds
What does the ferrel cell create
● mild wet climates (like the Uk)
●Storm weather,at 60⁰ due to rising air
Wha happens in polar cell
Cold air sinks at the poles (high pressure and moves toward 60⁰ where it meets warmer air and rises (low pressure)
Weather in high pressure zones
Dry and calm with clear skies.
e.g 30° north/south: Deserts like the Sahara.
Poles: Cold and dry conditions.
How Climate Change Affects Tropical Storms (simple)
Stronger Storms
More Rain
Higher Sea Levels
Changing Patterns
How Climate Change Affects Tropical Storms (lìmore infor)
Stronger Storms: Warmer oceans provide more energy, making storms more powerful.
More Rain: Warmer air holds more moisture, leading to heavier rainfall during storms.
Higher Sea Levels: Rising sea levels cause worse flooding from storm surges.
Changing Patterns: Tropical storms may happen in new places as oceans warm further from the equator.
Why the Equator Gets a Lot of Rain
Warm Air Rises: The heat causes air to rise (low pressure).
Cooling and Condensation: As the air rises, it cools, and water vapor condenses to form clouds.
Heavy Rainfall: These clouds produce frequent and intense rain, leading to tropical rainforests.
Why the Equator is Hot
The Sun’s rays hit the equator directly all year round. This concentrated sunlight makes it much hotter than areas further from the equator.
Response of typhhon Hayan
International Aid
Rebuilding
Infrastructure Damage
Homes, schools, and hospitals were damaged or destroyed.
Widespread power outages and communication breakdowns.
Economic Impact
Estimated damage of around $5.8 billion.
Many businesses were destroyed, leading to loss of income for many families.
Environmental Impact
Flooding: Coastal areas were severely flooded due to storm surges.
Land Damage: Crops, farmland, and trees were destroyed, affecting agriculture.
Human Impact
Deaths: Around 6,300 people were killed.
Injuries: Thousands of people were injured.
Displacement: Over 4 million people were left homeless.
Wha does the polar cell create
●Cold, dry conditions at the poles
●Stormy weather where polar air meets warmer air at 60⁰ (polar front)
