Test 10 domande Meteorology, tempo libero

1 - The formation of medium to large precipitation particles requires... A high cloud base. Strong wind. An inversion layer. Strong updrafts.

2 - Clouds are basically distinguished by what types? Stratiform and ice clouds Layered and lifted clouds Cumulus and stratiform clouds Thunderstorm and shower clouds

3 - Which force causes "wind"? Centrifugal force Thermal force Coriolis force Pressure gradient force

4 - The saturated adiabatic lapse rate should be assumed with a mean value of: 1,0° C / 100 m. 0° C / 100 m 0,6° C / 100 m 2° C / 1000 ft.

5 - Light turbulence always has to be expected... Above cumulus clouds due to thermal convection. Below stratiform clouds in medium layers. When entering inversions Below cumulus clouds due to thermal convection

6 - What condition may prevent the formation of "radiation fog"? Overcast cloud cover Calm wind Low spread Clear night, no clouds

7 - How do spread and relative humidity change with increasing temperature? Spread increases, relative humidity decreases Spread remains constant, relative humidity decreases Spread increases, relative humidity increases Spread remains constant, relative humidity increases

8 - Extensive high pressure areas can be found throughout the year ... In areeas showing extensive lifting processes In mid latitudes along the polar front Over oceanic areas at latitues around 30°N/S. In tropical areas, close to the equator

9 - Under which conditions "back side weather" ("Rückseitenwetter") can be expected? Before passing of an occlusion During Foehn at the lee side After passing of a warm front After passing of a cold front

10 - The barometric altimeter indicates height above... A selected reference pressure level. Mean sea level. Standard pressure 1013.25 hPa. Ground.
