1(no)
5(yes)

Question 12

What way does weather move?

Answer 12

It moves west to east.

Question 13

Can you identify the location of fronts, air masses, and high and low-pressure areas on isotherm and isobar maps?

Answer 13

1-5
1(no)
5(yes)

Question 14

What is an isotherm map?

Answer 14

An isotherm is a type of map that shows different temperatures using lines to connect areas of equal temperature.

Question 15

Where do hurricanes form?

Answer 15

Hurricanes form over warm water regions(usually by equator). They form in late summer and early fall because the ocean is warmest then.

Question 16

What causes the most damage in a hurricane?

Answer 16

The most damage is caused by storm surge. Due to the low pressure, water expands over the ocean, the strong winds push water over the top of itself, and the water goes onto land and can increase the sea level rapidly by up to 30 ft.

Question 17

Where do you get the most damaging winds in a hurricane?

Answer 17

The most damaging winds are found in the eye wall, which is right outside the center of the hurricane. The eye is relatively calm.

Question 18

What is the difference between a hurricane watch and warning?

Answer 18

A hurricane watch means that there is 24-36 hours before the hurricane hits, and a warning means there is less than 24 hours.

Question 19

How does a cold front form?

Answer 19

A cold front forms when colder air moves into a region of warmer air. The warmer air is forced upwards rapidly and cumulus and/or cumulonimbus clouds form. Short severe storms often happen.

Question 20

How does a warm front occur?

Answer 20

A warm front forms when warm air moves into a region of cold air. The warm air rises, and cools to form clouds. There is steady precipitation.

Question 21

How does an occluded front form?

Answer 21

An occluded front forms when a fast cold front overtakes a warm front and warm air is completely lifted off the ground.

Question 22

How does a stationary front form?

Answer 22

A stationary front forms when two air masses are headed towards each other and they do not displace each other. Winds blow parallel to the front.

Question 23

After a cold front passes the region, what is the temp. and pressure like?

Answer 23

The temp. decreases and the the pressure increases after a cold front passes.

Question 24

After a warm front passes the region, what is the temp. and pressure like?

Answer 24

The temp. increases and the the pressure decreases after a warm front passes.

Question 25

After an occluded front passes the region, what is the temp. and pressure like?

Answer 25

The temp. decreases and the the pressure increases after an occluded front passes.

Question 26

How does a thunderstorm form?

Answer 26

To start, warm moist air rises, then it cools and creates a cloud. A downdraft forms and creates precipitation and the cloud becomes cumulonimbus.

Question 27

How does lightning form?

Answer 27

Positive particles in the cloud are carried to the top and negative particles to the bottom. negative particles in the ground are repelled by the ones in the cloud and the positive particles are attracted. A string of negative particles called a step ladder head towards the surface and meets with an positive streamer. When the currents meet, a return stroke goes to the cloud and we see lightning.

Question 28

How does thunder form?

Answer 28

The heat caused by the lightning expands the air and cools air rushes in to replaces it.

Question 29

How and when does a tornado form?

Answer 29

They form when moist warm air meets cold air at the ground and a cold front forms. The warm air rises, and when it meets the cold air, it forms a thunderstorm. Jet streams creates a downdraft and makes the up and downdraft rotate. The rotating air within the storm funnels out and touches the ground and a tornado forms. Tornadoes mostly form in spring because there is the largest temp. difference between the air masses.

Question 30

Why does the polar front and jet streams matter to the formation of tornadoes?

Answer 30

Tornadoes form along the polar front because it has low pressure and jet streams. Jet streams make both the downdraft and updraft rotate, which causes the spiraling of a tornado.

Question 31

How do mid-latitude cyclones form?

Answer 31

To start, a stationary front forms. Then a wave develops (the front isn't straight). The wave breaks into a cold and warm front. Lastly, an occluded front forms (3 sections, one with cold, one with occluded, one with warm).

Question 32

What is the difference between an anticyclone and a cyclone?

Answer 32

Anticyclones have clear skies, and sinking air, and are in high-pressure systems. In an anticyclone, surface air goes outward and clockwise in the northern hemisphere. Cyclones have cloudy skies, and rising air, and are in low-pressure systems. In a cyclone, surface air goes inward and counterclockwise in the northern hemisphere.

Question 33

What is a hurricane?

Answer 33

A hurricane is a powerful storm with high wind speeds(75+ mph), low pressure, and lots of precipitation. It is fueled by rising moist air and latent heat from condensation. It is usually in a mT air mass.

Question 34

What specific air masses affect the US?

Answer 34

cP Canadian, mP Atlantic, mT pacific, mT gulf, cT Mexican, mP Atlantic, mT Atlantic

Question 35

In a warm front, what is the cloud series that occur?

Answer 35

Cirrus to alto stratus to stratus to nimbo-stratus.

Question 36

What is an isobar map?

Answer 36

A map that connects places of equal barometric pressure.
