It is not possible to give a definitive answer

Question 4

The following temperatures have been observed over a station at 1200 UTC. Assume the station is at MSL. Height in feet. Temperature in degrees C: 20000: -12; 18000: -11; 16000: -10; 14000: -10; 12000: -6; 10000: -2; 8000: +2; 6000: +6; 4000: +12; 2000: +15; surface: +15. Which of the following statements is correct?

Accepted Answer

Assuming that the MSL pressure is 1013.25 hPa the true altitude of an aircraft would actually be higher than the indicated altitude.

Answer

The height of the freezing level over the station is approximately 12000 FT.

Answer

The layer between 16000 and 18000 FT is absolutely unstable

Answer

The temperature at 10000 FT is in agreement with the temperature in the ICAO Standard Atmosphere.

Question 5

The radiation of the sun heats

Accepted Answer

The surface of the earth, which heats the air in the troposphere

Answer

The air in the troposphere only directly if no clouds are present

Answer

The water vapour in the air of the troposphere

Answer

The air in the troposphere directly

Question 6

An inversion is

Accepted Answer

An increase of temperature with height

Answer

A decrease of temperature with height

Answer

A decrease of pressure with height

Answer

An increase of pressure with height

Question 7

Which of the following processes will increase the stability of an air mass?

Accepted Answer

Cooling by the underlying surface.

Answer

Advection of colder air aloft.

Answer

Warming of the air mass from below.

Answer

Addition of water vapour in the lower layer.

Question 8

An air mass is stable when

Accepted Answer

Lifted air returns to its original level

Answer

Temperature in a given area drops off very rapidly with height

Answer

The lapse rate is 1°C per 100 m

Answer

Pressure is constant

Question 9

A wind speed of 350 kt within a jet stream core should be world-wide regarded as:

Accepted Answer

Possible but a very rare phenomenon.

Answer

Not unusual in polar regions.

Answer

A common occurrence.

Answer

Not possible.

Question 10

Convective clouds are formed

Accepted Answer

In unstable atmosphere

Answer

In mid-latitudes only

Answer

In summer during the day only

Answer

In stable atmosphere
