A

cold air moves towards warm air

20
Q

what is a warm front?

A

warm air moves towards cold air

21

A

boundary between two air masses stalls

22
Q

what is an occluded front?

A

cold front catches up with a warm front

23
Q

how do the different weather variables change as a cold front pass through?

A

many heavy storms go over, hail, sleet, snow, showers

24
Q

how do the different weather variables change as warm front passes through?

A

the temp goes up and there are stormy rains

25
define meteorologist
a scientist who studies/predicts weather. they use several specific factors or variables, to define atmospheric conditions/changes
26
define forecasting
predicting weather
27
what is doppler radar
a radar that uses the doppler affect to find velocity of item compared to radar
28
define climate
weather that stays the same over a long period of time
29
what is the relationship between weather patterns/climate
weather = isn't long lasting climate = long lasting
30
what is the biggest influence on climate?
the SUNNNNNN
31
how does latitude effect climate?
different locations = diff climates
32
define rain shawdows
when mountains block a rain cloud from coming on the other side, the other side doesn't get any rain
33
how did death valley form?
it was on the leeward side on the mountains
34
how do oceans affect temps and precips on land
cuz high specific heat
35
how do ocean currents affect climate
cold/warm ocean currents
