Global air circulation and local winds

Radiation fog occurs when.....

• the valley gets a gust of wind and radiates fog

• the valley sides are warmed by terrestrial radiation causing it to condense and form fog

• the valley floor cools the air in contact with it causing it to condense and form fog.

• the valley floor warms during the morning causing condesation and a cloud forms.

Anabatic winds blow......

• upslope at during the night

• upslope in the afternoon

• downslope during the night

• downslope in the afternoon.

Frost pockets form where the cold air ____________________ to the valley floor

• subsides

• subdues

• subdivides

• swooshes

A temperature inversion occur when .........

• Temperatures increase with an increase in altitude.

• Temperatures decrease with an increase altitude

• Temperatures remain constant with an increase in altitude

• Temperatures decrease with an decrease in altitude

Slope aspect is....................

• the angle of a slope relative to the valley fllor

• the angle of a slope relative to opposite slope

• the angle at which the sun's rays strike a slope

• the angle at which the sun's rays strike tall buildings in the city

Radiation fog occurs when.....

• the valley gets a gust of wind and radiates fog

• the valley sides are warmed by terrestrial radiation causing it to condense and form fog
