Flashcards in Intro into Meteorology Deck (29):
1

What is meteorology?

Study of atmospheric conditions and disturbances.

2

What is weather?

Current state of the atmosphere.

3

What is climate?

Long-term weather patterns.

4

What is the compositions of the atmosphere (percentages of what makes up the air we breathe)

78% = Nitrogen
21% = Oxygen
1% = Trace gases

5

Structure of the atmosphere: What are the four elements of weather?

Temp, pressure, wind, moisture

6

What kind of climate does California have?

A mediterranean climate. Winters are mild and don't get snow in most places and don't get the rain we need.

7

Layers of climate: What is the lowest layer?

Troposphere (All weather happens here) (Life zone) 5-10 miles thick

8

Layers of climate: What is the second lowest layer?

Stratosphere (Ozone layer) 10-20 miles thick

9

Layers of climate: What is the third lowest layer?

Mesosphere (20 miles thick)

10

Layers of climate: What is the highest layer?

Thermosphere (80 miles thick)

11

Layers of climate: What is the pause line between the Troposphere and Stratosphere?

Tropo Pause

12

Layers of climate: What is the pause line between the Stratosphere and the Mesosphere?

Strato Pause

13

Layers of climate: What is the pause line between the Mesosphere and the Thermosphere?

Meso Pause

14

What is temperature?

Measurement of molecular movement.

15

What kind of radiation does the sun give off?

100% Short-wave radiation.

16

What does the word scattering refer to?

The particle matter (water vapor, smoke, smog, pollen, dust, pollution, etc) that is in the air between the short-wave radiation and the ground of the earth.

17

What is the percentage of short-wave radiation that makes it/hits the ground?

about 47%

18

What is incoming solar radiation?

Insolation (can be absorbed, scattered, and/or reflected) *does NOT directly heat the atmosphere.

19

When solar radiation makes its way all the way to Earth, this is called what?

Absorption

20

When solar radiation goes back up to the air, this is called what?

Reflection

21

What is terrestrial radiation?

Long-wave radiation. (Heats the atmosphere)

22

Variations in temp worldwide are caused by what?

Several control factors.

23

As altitude increases, what happens to temperature?

It decreases.

24

What is the adiabatic lapse rate?

Temp. change in a moving air mass 5 1/2 divided by 1000

25

If you are 10,000 feet high in elevation and it's 56 degrees, and you walk down to a 2,000 feet high elevation, what is the temp now? (consider the adiabatic lapse rate - 5 1/2 divided by 1000).

100

26

What is the degree of the tilt in the Earth?

23 1/5

27

Because of the tilt in the Earth, this is the only reason why we have what?

The seasons. b/c of the angle of the sun and the length of a day.

28

Why are some ocean currents warm and others cold?

Depending on where the ocean current is coming from, if on the West side of the U.S the current will be cold because of the California Current and the East side of the U.S current will be warm because of the GolfStream.

29

Does land or water heat/cool faster?

Land heats and cools faster then water.
