Test 10 domande ATPL - Airline Transport Pilot license - Meteorology, tempo libero

1 - At the top of orographic waves, in mountainous regions, the cloud most likely to be encountered is Cirrostratus. Altocumulus lenticularis. Cumulus mediocris. Cirrus.

2 - Read this description: 'After such a fine day, the ring around the moon was a bad sign yesterday evening for the weather today. And, sure enough, it is pouring down outside. The clouds are making an oppressively low ceiling of uniform grey But at least it has become a little bit warmer.' Which of these weather phenomena is being described? A blizzard A warm front A cold front

3 - The station pressure used in surface weather charts is: QFF QNH QFE QNE

4 - The geostrophic wind is greater than the gradient wind around a low pressure system because the: Centrifugal force is added to the pressure gradient Centrifugal force opposes the pressure gradient Coriolis force opposes to the centrifugal force Coriolis force is added to the pressure gradient

5 - What is the classification of the air mass affecting position 'Q' at 0600 UTC?

Polar maritime Tropical maritime Tropical continental Polar continental

6 - The geostrophic wind depends on Earth's rotation, geographic latitude, centripetal force Geographic latitude, centripetal force, height Density, earth's rotation, geographic latitude Centripetal force, height, pressure gradient

7 - The final stage of a thunderstorm is reached when: No further electrical charge is developed. A well developed anvil can be seen. All of the above. The lower portion of the cloud dissipates.

8 - An air mass is called stable when The temperature in a given air mass decreases rapidly with height The pressure in a given area is constant The vertical motion of rising air tends to become weaker and disappears The environmental lapse rate is high, with little vertical motion of air currents

9 - Surface temperature inversions are frequently generated by Terrestrial radiation on a calm clear night Compression causing the release of latent heat in a layer of stratiform cloud Gusting winds increasing surface friction during the day with consequent mixing at the lower levels An unstable air mass causing convection currents and mixing of the atmosphere at lower levels

10 - When planning a flight at FL 60, which upper wind and temperature chart would be nearest your flight level ? 700 hPa 850 hPa 300 hPa 500 hPa
