06. Static Stability and Adiabatic Processes

Frage 1 von 10

1

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

Wähle eine der folgenden:

  • The environmental lapse rate.

  • The adiabatic lapse rate.

  • The temperature curve.

  • The tephigram.

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

Wähle eine der folgenden:

  • 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.

Erklärung

3- The DALR is greater than the SALR because:

Wähle eine der folgenden:

  • 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.

7- Neutral equilibrium in the atmosphere occurs when:

Wähle eine der folgenden:

  • 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.

Erklärung

Frage 8 von 10

1

8- Which of the following statements is true?

Wähle eine der folgenden:

  • 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.

Erklärung

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

Wähle eine der folgenden:

  • Lesser, released.

  • Greater, absorbed.

  • Greater, released.

  • Lesser, absorbed.

Erklärung
