THE ATMOSPHERE CAP1 Flashcards
Temp laps rate at the troposphere?
2 C /1000ft
0.65 C /100m
Troposphere height
From poles been 8 to equator been 16 km. average hight 11km
Min temps at poles and equator in the troposphere?
-40/50 C at poles and -75 C at the equator
What are the folds or breaks in the tropopause and whats the reason?
Hardley, Ferrel and Polar cells.
The huge differnces in temps between these air masses creates these folds and the height of the tropopause changes . (Jetstream)
Minimum Temp at the average tropopause? And also the min temp over poles and equator of the tropopause?
At 11km temp is -56,5 C at avg lats
At -75 C at the equator
At -40/50 C at the poles
The ozone layer height?And where is situated in terms of atm layers
25km
In the stratosphere
What is the height of mesosphere and minimum temp?
What is the name of the cloud that can extends to that levels?
Height from 50km above stratosphere to 90km .
From 0 C to -90C
Noctilucent
What is the termospehere height ?
From mesosphere and above so 90km upto 700km where the exosphere begins
What is the ionosphere?
Is a layer where UV and X ray radiation create a concentration of positive ions and free electrons which creates an electrostatic force which influence long range radio wave. (Sun emits short radio wave been more hotter)
ISA conditions ?
Temp 15 C Pressure 1013 hpa Density 1,225 kg/m3 ————— Temp decreases by 2C /100ft
Constant temp of -56,5C from 11km(FL360) up to 20km (FL650)
Increase of temp of 0.3 C /1000ft or 0.1C /100m from 20km (FL650) to 32km (105000ft)
6 important Pressure levels and pressure?
100hpa - FL530 150HPA -FL450 200HPA - FL380 300HPA -FL300 500HPA - FL180 (50% PREUSSRE AT SEA LEVEL) 700HPA - FL100
