Weather and climate Flashcards
Can you draw a diagram to show relief rainfall?
Can you draw a diagram to show frontal rainfall?
Can you draw a diagram to show convectional rainfall?
Can you name five key words from the water cycle? (Try to think about the spellings - they are tricky)
- Evaporation
- Condensation
- Precipitation
- Infiltration
- Interception
- Evapotranspiration
- Throughflow
- Surface flow/ runoff
What instrument would you use to measure air pressure?
A barometer
What instruments would you use to measure wind speed and direction?
Anemometer - wind speed
Wind vane - direction
What instrument would you use to measure rainfall?
A rain guage
How would you define the word ‘weather’?
The day-to-day state of the atmosphere at a particular time and in a particular place.
How would you define the word ‘climate’?
The average weather in a particular place, usually calculated over a 30 year average.
What is a microclimate?
The local climate of a small area.
What is a ‘front’ in weather terms?
The boundary between warm and cold air masses.
What is condensation?
When water vapour cools, it turns back into water droplets.
What word is described here:
“As liquid water is heated, the molecules turn into water vapour, a gas.”
Evaporation
What is infiltration?
When water on the surface seeps into the soil.
How does altitude influence temperatiure?
Temperature decreases by 1oC for every 150 metres gain in height.
What are the five main factors influencing the climate of the British Isles?
- Latitude
- Altitude
- Distance from the sea
- Prevailing wind
- Ocean currents
How does the North Atlantic Drift influence the climate of the British Isles?
The North Atlantic Drift is an ocean current that brings warm water from the Caribbean across the Atlantic to Britain. It makes our climate warmer than it should otherwise be.
How do buildings create their own microclimates?
Buildings change wind speed and direction, and because they give out heat, they can warm temperatures by 2-3oC.
What does ‘aspect’ mean?
The direction that something is facing.
Who does aspect effect temperature?
In Britain, places facing south are warmer than places facing north because they get more direct sunlight.
