Weather Hazards And Climate Change Flashcards
(44 cards)
What are the 3 types of weather cells
Hadley, polar and Ferrell cells
What is the UK’s weather driven by
The North Atlantic drift current
What causes the trade winds
Differences in pressure
What does low pressure mean
Cloudy and rising air which means rain.
What does high pressure mean
Clear sky’s falling air which means no rain and warm climate.
How can heat be redistributed around the world?
Trade winds and jet streams
What does the criollos effect do to jet streams
To curve like waves
Which way do storms spin in the northern hemisphere
Anti clockwise
Which way do storm spin in the Southern Hemisphere
Clockwise
What geological time frame are we in now
Inter glacial Holocene
What is a natural cause of climate change
The milankovitch cycles
Another natural cause of climate change
Meteor strikes- dust blocks the sunlight so photosynthesis can’t occur
Why is the earth warming up
Solar radiation getting trapped in by green house gases acting as a blanket
Why does the UK’s climate vary so much?
Because of maritime influences and altitude
Where do hurricanes form
Over warm waters along the equator
How do hurricanes move
They follow the prevailing winds
Why are hurricanes only a risk to coastal areas
They bring storm surges and they will lose they power when they go over land so won’t last long
Name a cases study on a hurricane
Hurricane sandy and typhoon haiyan
What human activities cause drought
Dams blocking flow of water, agriculture and deforestation
What are some meteorological characteristics
Level of dryness of an area, ocean currents, jet streams
What are some hydrological characteristics
Low precipitation, dry soil from no rain, low amount of dry water.
What are some consequences on global warming
Food production starts to decrease because of the temperatures rising which can effect the yield of crops
What is increasing the rate of global warming
Demand for: goods, food, energy and transport is getting higher. Which means more burning of fossil fuels.
How can we measure climate change.
Measuring ice cores, sea level and glacial features
