Answer

Formation of a high in the upper troposphere

Answer

Formation of a large ground low

Answer

Question 5

Which conditions are likely for the formation of advection fog?

Accepted Answer

Warm, humid air moves over a cold surface

Answer

Cold, humid air moves over a warm ocean

Answer

Warm, humid air cools during a cloudy night

Answer

Humidity evaporates from warm, humid ground into cold air

Answer

Calm wind, forming of shallow cumulus clouds

Answer

Calm weather, formation of lifted fog layers

Answer

Formation of high stratus clouds, ground-covering cloud bases

Question 8

Heavy downdrafts and strong wind shear close to the ground can be expected...

Accepted Answer

Near the rainfall areas of heavy showers or thunderstorms

Answer

During cold, clear nights with the formation of radiation fog

Answer

During approach to an airfield at the coast with a strong sea breeze

Answer

During warm summer days with high, flatted Cu clouds.

Question 9

What pressure pattern can be observed during the passage of a polar front low?

Accepted Answer

Answer

Rising pressure in front of the warm front, constant pressure within the warm sector, rising pressure behind the cold front

Answer

Falling pressure in front of the warm front, constant pressure within the warm sector, falling pressure behind the cold front

Answer

Rising pressure in front of the warm front, rising pressure within the warm sector, falling pressure behind the cold front

Question 10
