Question 1

A cumulus congestus is:

Accepted Answer

A cumulus that is of great vertical extent

Answer

A remnant of a CB

Answer

A cumulus with little vertical development

Answer

A cumulus that only occurs in association with the ITCZ

Question 2

In which of the following situations can freezing rain be encountered?

Accepted Answer

Ahead of a warm front in the winter

Answer

Behind a warm front in the summer

Answer

Ahead of a cold front in the winter

Answer

Ahead of a cold front in the summer

Question 3

The turbulence which occurs at high flight levels (above FL 250) is mainly of the type Clear Air Turbulence. In what way can moderate to severe Clear Air Turbulence affect an aircraft, the flight and the passengers?

Accepted Answer

The turbulence is a small scale one and can cause damage. The manoeuvring of the aircraft will be made more difficult or even impossible. For the passengers the flight will be unpleasant.

Answer

The turbulence can be resembled with the roughness of a washing-board (small scale) and will not have influence on the aircraft and its solidity, but will make flight a little more difficult. The passengers will seldom notice anything of this turbulence.

Answer

The turbulence is a large scale one (waving) so that the aircraft will be difficult to manoeuvre. The passengers will feel some discomfort.

Answer

The turbulence is wave like which makes the flight unpleasant for the passengers but the manoeuvring will not be affected essentially.

Question 4

Thunderstorms are often preceded by:

Accepted Answer

Altocumulus Castellanus

Answer

Nimbostratus

Answer

Altocumulus Lenticularis

Answer

Altostratus

Question 5

What relationship exists between the wind at 3000 feet and the surface wind?

Accepted Answer

The wind at 3000 feet is parallel to the isohypses and the surface wind direction is across the isobars toward the low pressure and the surface wind is weaker.

Answer

They are practically the same, except when eddies exist, caused by obstacles

Answer

They have the same direction, but the surface wind is weaker, caused by friction

Answer

The surface wind is veered compared to the wind at 3000 feet and is usually weaker.

Question 6

What is the approximate speed of a 90 km/h wind, expressed in knots?

Accepted Answer

50 kt

Answer

70 kt

Answer

60 kt

Answer

55 kt

Question 7

What is meant by an area of divergence?

Accepted Answer

An area where air masses are moving out.

Answer

A frontal zone.

Answer

An area where air masses are moving in.

Answer

A high pressure area.

Question 8

The presence of ice pellets at the surface is evidence that

Accepted Answer

Freezing rain occurs at a higher altitude

Answer

A cold front has passed

Answer

There are thunderstorms in the area

Answer

A warm front has passed

Question 9

The decrease in temperature, per 100 metres, in a saturated rising parcel of air at lower level of the atmosphere is approximately

Accepted Answer

0.6°C

Answer

1°C

Answer

1.5°C

Answer

0.35°C

Question 10

In which approximate direction does the centre of a non-occluded frontal depression move?

Accepted Answer

In the direction of the warm sector isobars.

Answer

In the direction of the sharpest pressure increase.

Answer

In the direction of the isobars ahead of the warm front.

Answer

In the direction of the isobars behind the cold front.
