wheather quiz 2

Question 1

How do you measure percipitation?

Answer 1

Using a rain gauge

Question 2

What are clouds

Answer 2

Liquid water droplets and/or ice crystals suspended in the atmosphere.

Question 3

When do clouds form?

Answer 3

Clouds form when the temperature of the air cools below the dew point, condensing water vapor.

Question 4

What do clouds also require

Answer 4

Clouds also require condensation surfaces (nuclei) such as dust, aerosols, & volcanic ash.

Question 5

what acronym causes clouds?

Answer 5

R.E.C.C

Question 6

What is fog?

Answer 6

Clouds very close to the Earth’s surface.

Question 7

What is visibility?

Answer 7

The distance you can see along the Earth’s surface expressed in miles.

Question 8

When does atmospheric transparency decrease?

Answer 8

it decreases when humans add pollutants to the atmosphere

Question 9

When does transparency increase?

Answer 9

it increases following precipitation

Question 10

What acts as a cleaner to the atmosphere?

Answer 10

precipitation

Question 11

What causes weather to change

Answer 11

when air masses move into an area

Question 12

What is air mass

Answer 12

a mass of air with uniform moisture and temperature characteristics

Question 13

How are air masses named?

Answer 13

they are named based on their source region

Question 14

What do we do to name air masses

Answer 14

we consider the moisture and temperature characteristics of the region source

Question 15

what are fronts?

Answer 15

boundary (interface) between two air masses

Question 16

description of a cold front

Answer 16

advancing cold air pushes warm air up violently and quickly creating storms on the frontal boundary.

Question 17

What forms in cold fronts?

Answer 17

cumulonimbus clouds

Question 18

describe a warm front?

Answer 18

advancing cold air pushes warm air up gently and slowly creating gentlestorms in ftront of the boundary.

Question 19

describe an occluded front

Answer 19

– when two cold air masses meet they push the warm air between them upward.

Question 20

what do occluded fronts create?

Answer 20

unpredictable weather

Question 21

Describe a stationary front?

Answer 21

when a cold air mass meets a warm air mass and neither interact.

Question 22

What can stationary fronts create?

Answer 22

-Can create long periods of unstable conditions.

Question 23

What happens at the frontal boundaries?

Answer 23

Warm air is forced to rise because it is less dense. This creates convection and causes clouds to form and possibly precipitate

Question 24

What are Cyclones?

Answer 24

low pressure systems?

Question 25

describe cyclones

Answer 25

Lowest pressure at the center Winds blow inward & counterclockwise Associated with converging, warm air, cloudy, and stormy weather

Question 26

What are anticyclones?

Answer 26

high pressure systems

Question 27

describe anticyclones

Answer 27

Highest pressure at the center Winds blow outward & clockwise Associated with clear, cool, calm weather H.O.C (High, Outward, Clockwise)

Question 28

Where do fronts typically move?

Answer 28

southwest to northeast

Question 29

What are most storms associated with?

Answer 29

Most storms are associated with high winds, heavy precipitation, and low pressure cyclones.

Question 30

What are hurricanes?

Answer 30

low pressure cyclone

Question 31

Describe formation and fuel of hurricanes.

Answer 31

Form in late summer to early fall Form off the coast of Africa near the equator Require warm ocean water Low pressure Strong winds

Question 32

how many stages of hurricanes are there?

Answer 32

5

Question 33

Where are hurricanes pushed to and why?

Answer 33

Hurricanes are pushed west toward the USA by the prevailing winds between 0˚ and 30˚N and bend to the right due to the Coriolis Force.

Question 34

What is the eye of the storm?

Answer 34

The Eye is the center of the Low pressure storm and has the lowest pressure readings.

Question 35

how are conditions inside the eye

Answer 35

Conditions are relatively clear and calm inside the Eye.

Question 36

how do hurricanes lose their streangth?

Answer 36

*Hurricanes lose their strength as they move onto land or move away from warm waters.

Question 37

What are thunderstorms?

Answer 37

A heavy rain storm accompanied by thunder and lightning

Question 38

What is the deadliest aspect of thunderstorms?

Answer 38

The lightning is the deadliest aspect of these storms.

Question 39

How do thunderstorms form?

Answer 39

Convection currents push warm moist air upward and cool air down.

Question 40

What are tornadoes

Answer 40

The most violent of all storms. A tornado is a rapidly rotating, extremely low pressure storm that drops down from a thunderstorm cloud.

Question 41

What are the differences of tornadoes between hurricanes

Answer 41

Form over land (Midwest USA) Smaller in diameter Faster wind speeds Last only for minutes, not days Winds are the most dangerous aspect

Question 42

what is a blizzard?

Answer 42

Storms with high wind speeds and heavy snow fall. Essentially a winter hurricane.
