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
