Question 1

Extensive high pressure areas can be found throughout the year ...

Accepted Answer

Over oceanic areas at latitudes around 30°N/S

Answer

In tropical areas, close to the equator

Answer

In areas showing extensive lifting processes

Answer

In mid latitudes along the polar front

Question 2

What frontal line divides subtropical air from polar cold air, in particular across Central Europe?

Accepted Answer

Polar front

Answer

Warm front

Answer

Cold front

Answer

Occlusion

Question 3

What process results in the formation of "orographic fog" ("hill fog")?

Accepted Answer

Warm, moist air is moved across a hill or a mountain range

Answer

Prolonged radiation during nights clear of clouds

Answer

Evaporation from warm, moist ground area into very cold air

Answer

Cold, moist air mixes with warm, moist air

Question 4

The term "trigger temperature" is defined as the temperature which...

Accepted Answer

Must be obtained at ground level so Cumulus clouds can be formed by thermal lifts

Answer

Is reached by a thermal lift during ascend when formation of Cumulus clouds begins

Answer

Is the maximum temperature at ground level that can be reached without formation of a thunderstorm from a Cumulus cloud

Answer

Is the minimum temperature at ground level that has to be reached so formation of a thunderstorm from a Cumulus cloud can occur

Question 5

What type of turbulence is typically found close to the ground on the lee side during Foehn conditions?

Accepted Answer

Turbulence in rotors

Answer

Clear-air turbulence (CAT)

Answer

Inversion turbulence

Answer

Thermal turbulence

Question 6

What clouds and weather can typically be observed during the passage of a cold front?

Accepted Answer

Strongly developed cumulus clouds (Cb) with showers of rain and thunderstorms, gusting wind followed by cumulus clouds with isolated showers of rain

Answer

Wind becoming calm, dissipation of clouds and warming during summer; formation of extended high fog layers during winter

Answer

Cirrus, thickening altostratus and altocumulus clouds, lowering cloud base with rain, nimbostratus

Answer

In coastal areas during daytime wind from the coast and forming of cumulus clouds, dissipation of clouds during evening and night

Question 7

With other factors remaining constant, decreasing temperature results in...

Accepted Answer

Decreasing spread and increasing relative humidity

Answer

Increasing spread and increasing relative humidity

Answer

Decreasing spread and decreasing relative humidity

Answer

Increasing spread and decreasing relative humidity

Question 8

What information can be obtained from satellite images?

Accepted Answer

Overview of cloud covers and front lines

Answer

Turbulence and icing

Answer

Temperature and dew point of environmental air

Answer

Flight visibility, ground visibility, and ground contact

Question 9

An inversion is a layer ...

Accepted Answer

With increasing temperature with increasing height

Answer

With constant temperature with increasing height

Answer

With increasing pressure with increasing height

Answer

With decreasing temperature with increasing height

Question 10

What weather conditions can be expected in high pressure areas during summer?

Accepted Answer

Calm weather and cloud dissipation, few high Cu

Answer

Changing weather with passing of frontal lines

Answer

Squall lines and thunderstorms

Answer

Calm winds and widespread areas with high fog
