25
what are all the steps to the water cycle
evaporation and transporation, condensationprecipation, runoff, infilitration
26
jet stream
narrow band of fast-moving, high altitude air
27
coriolis effect
the apparent deflection of an object due to earths rotation
28
air mass
large volume of air with uniform moisture and temperature throughout
29
weather fronts
air masses interact in zones
30
is there only one jet stream in the world
4
31
how many pressures are there
2
32
what is the low pressure system also known as
a low (l)
33
which direction does a low pressure system flow
counterclockwise
34
what is the result of low pressure system
air rises, clouds form, created precipitation
35
what is a high pressure system also known as
a high (h)
36
which direction does a high pressure system flow
clockwise
37
what is the result of high pressure systems
causes air to sink which results in clear skies
38
which stystem do high pressure sytems flow
away from center
39
what are the 4 weather fronts
cold front, warm front, stationary front, occluded front
40
what are cold fronts caused by
cold air forces warm air upward in a fast chaotic manner
41
what is a cold front represented by on the news
by blue triangles
42
how are warm fronts caused
warm air rises gently above cold air
43
what is the warm front represented by on the news
red cicles
44
how are staionary fronts formed
cold and warm air masses meet and neither front advances
45
how are stationary fronts represented on the news
half circle triangle
46
how are occluded fronts formed
fast moving cold front overtakes a slow warm front
47
how are occluded fronts represented on the news
purple triangle and half circle
48
maritime climate
a climate that is strongly affected by the ocean
49
continental climate
a climate that is not directly affected by an ocean
50
sea breeze
blows from over the water toward land in the afternoon when the land is warmer than the water
51
what is climate
the long term average of weather condition
52
what is weather
day to day outside condition
