Question 1

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

Accepted Answer

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

Answer

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

Answer

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

Question 2

What information can be found in the ATIS, but not in a METAR?

Accepted Answer

Operational information such as runway in use and transition level

Answer

Information about current weather, for example types of precipitation

Answer

Approach information, such as ground visibility and cloud base

Answer

Information about mean wind speeds, maximum speeds in gusts if applicable

Question 3

What conditions are favourable for the formation of thunderstorms?

Accepted Answer

Warm humid air, conditionally unstable environmental lapse rate

Answer

Warm and dry air, strong inversion layer

Answer

Clear night over land, cold air and patches of fog

Answer

Calm winds and cold air, overcast cloud cover with St or As

Question 4

What cloud sequence can typically be observed during the passage of a warm front?

Accepted Answer

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

Answer

Squall line with showers of rain and thunderstorms (Cb), 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

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

Question 5

How can wind speed and wind direction be derived from surface weather charts?

Accepted Answer

By alignment and distance of isobaric lines

Answer

By annotations from the text part of the chart

Answer

By alignment of lines of warm- and cold fronts

Answer

By alignment and distance of hypsometric lines

Answer

0,65° C / 100 m.

Question 7

Under which conditions "back side weather" ("Rückseitenwetter") can be expected?

Accepted Answer

After passing of a cold front

Answer

After passing of a warm front

Answer

During Foehn at the lee side

Answer

Before passing of an occlusion

Question 8

The "spread" is defined as...

Accepted Answer

Difference between actual temperature and dew point.

Answer

Relation of actual to maximum possible humidity of air.

Answer

Difference between dew point and condensation point

Answer

.+20° to -5° C

Answer

.+5° to -10° C

Answer

.-20° to -40° C

Question 10

Which of the following conditions are most favourable for ice accretion?

Accepted Answer

Temperatures between 0° C and -12° C, presence of supercooled water droplets (clouds)

Answer
