humidity, condensation, and clouds - II

Question 1

How is dew formed?

Answer 1

earth’s surface cools down, the air touching earth’s surface cools to dew point temperature, earth’s surface cools below earth’s temperature, water vapor forms droplets on surface

Question 2

What is dew point temperature’s relationship with temperature?

Answer 2

dewpoint temperature is always less than or equal to temperature, dew point falls with temperature

Question 3

What does a higher dew point temperature indicate?

Answer 3

the air contains more moisture

Question 4

What is frost point temperature?

Answer 4

when dew point temperature falls below freezing (0°C), frost forms instead of dew

Question 5

What is radiation fog?

Answer 5

fog produced by radiational cooling, formed at night with little to no wind

Question 6

What is advection fog?

Answer 6

fog produced when warm, moist air goes over cool surfaces. the air temperature drops todew point and forms fog

Question 7

What is upslope fog?

Answer 7

fog produced when moist air flows up along an elevated plain, hill, or mountain

Question 8

What is evaporation fog?

Answer 8

fog formed when mixing warm unsaturated air with cool unsaturated air. after mixing, air becomes saturated and forms fog.

Question 9

What is the classification “cirro”?

Answer 9

high clouds, 6-7 km

Question 10

What is the classification “alto”?

Answer 10

middle clouds, 2-7 km

Question 11

What is the classification “low”?

Answer 11
