06. Static Stability and Adiabatic Processes

Question 1 of 10

1

1- The actual change of temperature with height is known as:

Select one of the following:

  • The environmental lapse rate.

  • The adiabatic lapse rate.

  • The temperature curve.

  • The tephigram.

Explanation

Question 2 of 10

1

2- In a saturated atmosphere air which is forced to rise will:

Select one of the following:

  • Tend to regain its former position if the ELR is less than the SALR.

  • Tend to regain its former position if the ELR is greater than the SALR.

  • Carry on rising if the ELR is less than the SALR.

  • Classified as stable air when the ELR is greater than the SALR.

Explanation

Question 3 of 10

1

3- The DALR is greater than the SALR because:

Select one of the following:

  • Saturated vapour pressure increases with increasing temperature.

  • Convection is more active in dry than in moist air.

  • The rate of cooling of saturated air is reduced by the release of latent heat of condensation.

  • Because of the release of latent heat of evaporation.

6- If the temperature near the surface in Hong Kong is +31oC then rising saturated air will cool at a rate of:

Select one of the following:

  • 3 oC / 1000 ft

  • 2,5 oC / 1000 ft

  • 1,5 oC / 1000 ft

  • 1oC / 1000 ft

7- Neutral equilibrium in the atmosphere occurs when:

Select one of the following:

  • Any air which is displaced upwards remains in its new position, once the displacing force is removed. This displaced air having no tendency to rise further or to sink back down.

  • There is a thin stable layer at low levels but a much thicker unstable layer aloft.

  • There is a state in which there is high relative humidity at low levels and a low relative humidity at high levels.

  • There is a state in which there is a low relative humidity at low levels and a high relative humidity at high levels.

Explanation

Question 8 of 10

1

8- Which of the following statements is true?

Select one of the following:

  • The tropopause is the dividing line between the stratosphere and the tropopause.

  • Stability increases as the environmental lapse rate decreases.

  • Heat is added to the environment by the evaporation of rain drops.

  • High surface temperatures and a plentiful supply of moisture are the only
    conditions required for the development of thunderstorms.

Explanation

Question 9 of 10

1

9- When condensation takes place, the higher the temperature the _____ the amount of latent heat _____.

Select one of the following:

  • Lesser, released.

  • Greater, absorbed.

  • Greater, released.

  • Lesser, absorbed.

Explanation

Question 10 of 10

1

10- The air is stable if:

Select one of the following:

  • It moves very little.

  • There are a few changes in pressure.

  • When a lifting force is removed the air tries to return to its original
    position.

  • When a lifting force is removed the air continues to rise.
