Unit 1A-Weather Hazards
Global Atmospheric Circulation
Transfer of heat from equator to poles with air movement
Divided into 3 cells from equator to poles
Hadley
Feral
Polar
Rising air=Low pressure Sinking air=High pressure
Wind blows from high to low pressure areas
Tropical Storms
Develop near equator
Conditions
Clusters of storms
Water deepness 70m or more
Low wind speeds
Sea temperature 26/27 degrees or more
Features
Circular shape
Anticlockwise spin
Eye of storm in middle
Typhoon Haiyan
Effects
Primary
8000 dead
$13 million damage
1 million houses destroyed
Secondary
Unemployment
Diseases
Landslides
Responses

UK Weather Hazards
Strong winds
Heavy rainfall
Snow and Ice
Drought
Thunderstorms
Heatwaves
Example: Beast from East or 2020 Heatwaves
Climate Change
Sea temperature risen by 0.9 degrees
Frequency of storms increased due to sea temperature increase
Distribution increased
Intensity increased
We can manage these with PPP (Prediction, Protection, Planning)
