Answer

Stratus

Answer

Cirrus

Question 4

Moderate to severe turbulence has to be expected...

Accepted Answer

On the lee side of a mountain range when rotor clouds are present.

Answer

Below thick cloud layers on the windward side of a mountain range

Answer

With the appearance of extended low stratus clouds (high fog).

Answer

Overhead unbroken cloud layers.

Question 5

The character of an air mass is given by what properties?

Accepted Answer

Region of origin and track during movement

Answer

Wind speed and tropopause height

Answer

Environmental lapse rate at origin

Answer

Temperatures at origin and present region

Question 6

Accepted Answer

Haze (HZ)

Answer

Radiation fog (FG)

Answer

Mist (BR)

Answer

Patches of fog (BCFG)

Question 7

What visual flight conditions can be expected after the passage of a cold front?

Accepted Answer

Good visiblity, formation of cumulus clouds with showers of rain or snow

Answer

Poor visibility, formation of overcast or ground-covering stratus clouds, snow

Answer

Medium visibility with lowering cloud bases, onset of prolonged precipitation

Answer

Scattered cloud layers, visbility more than 5 km, formation of shallow cumulus clouds

Question 8

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

Accepted Answer

Lower than the dry adiabatic lapse rate.

Answer

Proportional to the dry adiabatic lapse rate

Answer

Higher than the dry adiabatic lapse rate.

Answer

Equal to the dry adiabatic lapse rate.

Accepted Answer

An atmospheric layer with constant temperature with increasing height

Answer

A boundary area between two other layers within the atmosphere

Answer

An atmospheric layer where temperature decreases with increasing height

Answer

An atmospheric layer where temperature increases with increasing height
