Q

Windy conditions do what?

A

Disperse water vapor in air and evaporation increases

17
Q

What is evaportranspiration?

A

Combined process of water vapor entering air from two land sources

18
Q

Annual precipitation is greater than what?

A

Mass water vapor entering air from two land sources

19
Q

What is relative humidity?

A

Ratio of annual water vapor to air’s water vapor capacity

20
Q

What is dew point temperature?

A

Temperature air must cool to reach saturation

21
Q

What is sensible temperature?

A

Temperature a person’s body feels

22
Q

When does condensation occur?

A

Air must be saturated and have surface to form droplets

23
Q

What is condensation nuclei?

A

Particles that serve as collection points for water molecules during condensation

24
Q

What is supersaturated?

A

Further cooling of saturated air with no surface to condense upon

25
Q

What is adiabiatic rate?

A

Water persisting in liquid forms at below freezing temperatures

26
Q

What is lifting condensation level?

A

Altitude that rising air reaches dew point, saturates, and condenses, forming clouds

27
Q

When does condensation begin?

A

As condensation begins, latent heat is released

28
Q

What is saturated adibatic rate?

A

Diminished rate of cooling

29
Q

Sinking air warms up at what rate?

A

At dry adiabatic rate

30
Q

What’s the trade off?

A

Air mass cools, pushes up into the system

31
Q

We live in what?

A

A rain shadow

32
Q

What are clouds?

A

Collections of minute liquid water droplets or ice crystals

33
Q

How do you classify clouds?

A

Based on two factors: form and altitude

34
Q

What are cloud forms?

A

Cirrus (cirriform), stratus (stratiform), cumulus (umuliform)

35
Q

What is cirrus?

A

Thin and wispy ice crystals

36
Q

What is stratus?

A

Grayish sheets

37
Q

What are cumulus?

A

Vertically large, rounded

38
Q
