Question 2

A Foehn wind occurs on the

Accepted Answer

Leeward side of a mountain range and is caused by significant moisture loss by precipitation from cloud

Answer

Windward side of a mountain range and is caused by surface heating

Answer

Leeward side of a mountain range and is caused by the condensation level being lower on the leeward side than on the windward side

Answer

Windward side of a mountain range and is caused by surface cooling and reverse air flow

Question 3

Stratus formed by turbulence will occur when

Accepted Answer

In the friction layer mixing occurs by turbulence and the condensation level is situated below the top of the turbulent layer

Answer

The wind speed is less than 10 kt and the air is heated by the earth's surface

Answer

The wind speed is greater than 10 kt and the condensation level is situated just above the turbulent layer

Answer

Absolute instability exists at low level
