atmospheric layer - Coggle Diagram
atmospheric layer
Atmospheric pressure
Measuring unit
bar
=1000mbar
Normal pressure
1013.25
at the sea level
decrease when height increase
Air density increase
notes
50% air in 3 Km
90% air in 16 Km
Layers
2-Stratosphere
ozonic layer
1-Troposhere
Disturbed layer
all turblances take place in it
Height:13 Km
pressure:100mabr(AIT)
75% of air mass
99% of water vapour
Air movement:vertical
Temperature
Temperature decrease 6.5 c each Km
Temp at top = temp at foot - Change in temp
Temp at foot = temp at top + Change in temp
Change in temp.=height(km)x(6.5
Change = temp at foot - temp at top
Instruments
Aneroid
Determine the possible day weather
Based on atmospheric pressure
Altimeter
in aeropalnes
measure the elevation of navigation
Atmospheric pressure maps
Isobar
curved lines which joins the equal pressure points together
Symbols
"L":Low
"H":High
atmospheric pressure
importance
to detect the wind direction
from "H" to "L"
