What is the composition of atmosphere
-Gases: Nitrogen,Oxygen,Argon ,Carbon dioxide ,ozone , water vapour
-Liquids:water drops
-Solids:dust,volcano ash , soot
Name the layers of the atmosphere(TSMTEI)
Troposhpere
Stratosphere
Mesosphere
Thermosphere
Exosphere
Ionosphere
Troposphere
-closest to Earth
-weather takes place there
-tropopause is the buffer layer
Stratosphere
-extends to 50 km above the Earth
-Ozone’s home
-commercial airlines and jets fly there (to avoid turbulence)
-buffer longer -stratopause
Mesosphere
-50-85km above surface
- temp:-90C
-buffer layer:mesopause
Thermosphere
- 90 to 1000km,
-temperature affected by sun 500-2000 C
Exosphere
- 10 000km,
- satellites orbiting there
Ionosphere -
- separate layer,
-top part of mesosphere and all thermosphere and exosphere
Which factors affect a regional climate?
-Latitude
-presnece of ocean currents
-Long-term atmospheric circulation
-Elevation
-Earth´s surface character
-Anthropogenic influences
How elvation affect climate?
Elevation rises ,it is cooler and cold seasons last longer
What is weather?
Short-term state of the atmosphere
What is climate?
Long-term pattern of weather
Name 3 major climate zones.
Polar, Temperate, Tropical
Define tropical wet climate zone.
Rainforests, no seasons, around the Equator
In which climate zone monsoons occur?
Tropical dry climate
What is typical for temperate climate zone?
4 seasons
Which climate zone is located around and beyond Arctic Circle?
Subarctic
Define global winds in equatorial area.
single cell - air warms up at the Equator towards the Poles-cold wind moves back to the Equador
Where we can find Westerlies and Ferrel cell?
Middle Latitudes
Characterize sea breeze.
SEA BREEZE - land warms up, air warm and rises, local area low pressure and cool air from the sea flows to the shore
Characterize land breeze
LAND BREEZE - during the night when water is warmer than the shore, flows from shore to the sea, lake
What is Foehn?
Type of dry, relatively warm, downslope wind that occurs in the lee of mountain range
Define temperature inversion.
Temperature increases with increasing altitude
Characterize low pressure system.
-Air pressure has dropped below the standard atmospheric pressure
-wind rotates inward in a counter-clockwise direction in NH, and clockwise direction in SH(cyclone)
