Weather Test - Tuesday

Question 1

climate

Answer 1

• long term weather averages (50 year)
• climate change: change in measurable data over long time
• humans are a huge role in changing climate

Question 2

F

Answer 2

F = (C • 1.8) + 32

Question 3

C

Answer 3

C = (F - 32) / 1.8

Question 4

types of clouds

Answer 4

• cirrus
• stratus
• cumulus

Question 5

cloud formation

Answer 5

• clouds are formed by condensation of water from a warmer temp. to a cooler temp.
• mixes with dust particles
• not like water droplets on your car or on grass

Question 6

weather

Answer 6

• weather is the state of atmosphere (life + activities) in short term (min. - 15 days) variations
• measurements: temperature, air pressure and humidity

Question 7

continental tropical

Answer 7

cT; hot; dry

•moisture evaporates in air

Question 8

continental polar

Answer 8

cP; cold-cool; dry
•usa winter
•clear weather to usa summer

Question 9

maritime polar

Answer 9

mP; cool; moist
•cloudy, damp weather
•from northern Atlantic + Pacific

Question 10

maritime tropical

Answer 10

mT; hot; humid
•warm temps + copious moisture
•usa, southern atlantic and gulf of mexico

Question 11

continental artic

Answer 11

cA; extreme cold; dry
•extreme cold, little moisture
•originate north of Arctic circle - darkness cools air
•usa + canada winter

Question 12

cold front

Answer 12

• frigid air + dry frost
• steep slope –> goes under warm air + pushes it up
• boundary between cold + warm air

Question 13

fronts

Answer 13

boundary between two air masses

Question 14

warm front

Answer 14

• warm air replaces cold air
• boundary between warm and cold
• warm air rides over heavy cold air
• as warm air rises the vapor forms into clouds –> precipitation
• wet weather can be connected with warm fronts

Question 15

stationary front

Answer 15

• 2 air masses come together and neither displace each other
• hard to predict weather
• resembles warm front
• complete grid lock/long time storms

Question 16

occluded front

Answer 16

• cold fronts “catch” warm front
• cold front moves quicker than warm front
• one eating the other
• cold front rotates around warm front

Question 17

3 measurements of weather

Answer 17

• temperature
• humidity
• air pressure

Question 18

3 forms of water

Answer 18

•solid
•liquid
•gas
S-L-G (add heat)
G-L-S (remove heat)

Question 19

high pressure system

Answer 19

• atmospheric pressure is higher
• air moves OUT of a h.p.s.
• air circulates clockwise
• curves RIGHT
• High –> Low
• air around is lower

Question 20

low pressure system

Answer 20

• atmospheric pressure is lower
• air moves INTO a l.p.s.
• air circulates counterclockwise
• all air around is higher
• curves to RIGHT
• High –> Low

Question 21

Hurricanes

Answer 21

"tropical cyclone"
•rotating low pressure system
-formed by warm, moist air evaporating + rising then spinning as a l.p.s.
•tropical depression: up to 39 mph
•tropical storm: 39-74 mph
•categories 1-5 start at 74 mph
-wind speed

Question 22

tornados

Answer 22

•form of thunderstorm
•rotating wind funnels down from clouds to the ground
•visible due to condensation of water + dust from clouds and any debris they pick up
•Fujita scale:
f0: 45-78; f1: 79-117; f2: 118-161; f3: 162-209; f4: 210-261; f5: 262-317

Question 23

tsunami

Answer 23

• “seismic sea waves”
• caused by underwater earthquakes, volcanoes or meteors hitting the water
• visualize a wave pool
• very rare
• 600 mph speed in seep water
• 30 meter average max. height
