The study if the earths atmosphere is called…
Meteorology
What is atmosphere?
The envelope of gases surrounding the earth
Someone who studies the earth…
Meteorologist
What are the layers of the earth’s atmosphere in order from the furthest to the closest.
Thermosphere Mesosphere Stratosphere Troposphere (where our weather takes place)
Heat comes from the sun. What happens to it in our atmosphere?
The heat from the sun is trapped, this heat creates our weather.
What type of climate zone are we located in and what does it mean?
Temperate, no extremes of temperature or rainfall NI has less sunshine and more rain than other parts of UK
What are Airmasses?
Winds which blow towards NI from different direction all the time bringing different weather They are defined by temperature and water content
Label a diagram of British Isles with 5 different Airmasses
See notes
What are the 7 elements of the weather?
Temperature Precipitation, eg rainfall Wind speed and direction Cloud cover and visibility Air pressure Humidity (amount of water vapour in the air) Sunshine
Temperature Definition and how is it measured?
Measure of how hot/cold something is. Thermometer, most common scale oC Celsius NB sun heats earth and this heats the air
Precipitation Definition and how is it measured?
Water in the air that falls on the ground e.g. rain, snow, sleet, hail, ice, fog Measured in mm using a rain gauge
Wind speed Definition and how is it measured?
Moving air Measure speed (strength) using a anemometer (spinning cups)in km/hr or knots Direction using a weather vane expressed as points of a compass from the direction it is coming from eg southerly wind comes from south travels north.
Air pressure Definition and how is it measured?
Pressure of air around us Barometer, units millibars (mb)
Cloud cover Definition and how is it measured?
Amount of sky covered by cloud It is measured in eighths, units oktas
What are the three main types of clouds?
High level Medium level Low level
