- Atmosphere
- Structure
- Troposphere
- closest to the earth and most weather happens here
- extends up 12km
- temp. decreases with altitude
- due to earths surface warms troposphere so further away=cooler
- Wind speeds increase
- Most unstable layer
- end of this sphere is marked by the tropoPAUSE
- An isothermal layer where temp remains constant
- boundary between troposphere and stratosphere
- Lots of turbulence as warm air raises and cool air sinks
- lots of clouds due to high water vapour
- closest to the earth and most weather happens here
- Stratosphere
- Steady increase in temp.
- due to ozone layer absorbing UV radiation
- StratoPAUSE boundary between stratosphere and mesosphere
- atmosphere is thinner here
- 12km-50km up
- Steady increase in temp.
- Mesosphere
- temp. decreases to -90
- due to being warmed by stratosphere further away=cooler
- Untitled
- due to being warmed by stratosphere further away=cooler
- no water vapour or dust to absorb radiation
- very strong winds at 3000km/h
- 50km-85-90km
- mesoPAUSE boundary between mesosphere and thermosphere
- temp. decreases to -90
- Thermosphere
- Increase in temp. from the absorption of UV radiation from small amounts of oxygen
- 85-90-1000km
- CLIMATE BASICS
- WEATHER
- SHORT-TERM atmospheric conditions in a particular place
- e.g. temo., cloud cover, wind speed
- SHORT-TERM atmospheric conditions in a particular place
- CLIMATE
- LONG-TERM atmospheric conditions in a particular place
- e.g. average measurements of temp
- LONG-TERM atmospheric conditions in a particular place
- atmosphere contains dry air and water vapour
- Dry air is mixture of gases including nitorogen (78%), oxygen(21%)
