Answer:
As the temperature inversion occurs around this zone
Step-by-step explanation:
- Troposphere The lowest layer of atmosphere found on the surface of the earth from 0 to 30 kilometers it's wider in equator i.e 18 km and narrows at poles till 6-8 km only. At this layer, 90 % of all convective activity takes place, turbulence and cloud formation like stuff.
- Consists of 80% of water vapor and dust particles. In troposphere the temperature in the air decrease with gain in height with a height of an overall positive lapse rate of 6.5 degrees C / km. The onset of tropopause the region where mixing stops and temperature remains constant and extends up to a layer of 11 to 20 kilometers.
- However, lapse rate variation sometimes occurs in between this sphere and affects the altitude of the tropopause. The seasonal effect is strongest at the mid-latitudes and varies with changes latitudes.
