Ch. 6 Meteorology for Pilots - A - Basic Weather Theory

Question 1

what is the troposphere?

Answer 1

The layer of the atmosphere extending from earth’s surface to an avg. altitude of 36,000ft.

Question 2

What is the tropopause?

Answer 2

It is a level, not a layer which acts like a lid to confine most of the water vapor and associated weather to the troposphere.

Question 3

What is the stratosphere?

Answer 3

It is a layer of the atmosphere. It has a similar composition to the troposphere except less water vapor.
it extends to approximately 160,000 ft.

Question 4

What are the two layers of the atmosphere above the stratosphere?

Answer 4

The Mesosphere and Thermosphere. They have little practical influence over weather.

Question 5

Does the height of the Troposphere change?

Answer 5

Yes, the height of the troposphere and tropopause are lower near the poles, and in winter. Higher near the equator and in the summer.

Question 6

If you captured a cubic foot of the atmosphere, what gases would you find and at what proportions?

Answer 6

Nitrogen (78%) ; Oxygen (21%) ; Argon, carbon dioxide, and other gasses makeup (1%)
Water vapor would range from 0-4%

Question 7

To what altitude above ground do gasses exist in fairly uniform proportions?

Answer 7

Up to approximately 260,000ft.
