jet stream
27
the apparent deflection of an object due to Earth's rotation
coriolis effect
28
a large volume of air with uniform moisture and temperature throughout
air mass
29
what are the zones in which air masses interact called?
weather fronts
30
how many jet streams are there in the world?
four
31
how many pressure systems are there? what are they?
two, the low and high pressure system
32
what are low pressure systems also known as?
a low
33
which direction does a low rotate?
counter clockwise
34
what are some results of a low pressure system?
air rises, causing cloud formation and precipitation
35
what is a high pressure system known as?
a high
36
which direction does a high pressure systen rotate?
clockwise
37
what is a result of a high pressure system?
air sinks, resulting in clear skies
38
what the four weather fronts?
cold, warm, stationary, and occluded
39
how are cold fronts created?
when cold air forces cold air upward in a fast and chaotic manner
40
how are cold fronts represented in weather forecasts?
with blue triangles
41
how are warm fronts created?
when warm air gently rises above cool air?
42
how are warm fronts represented in weather forecasts?
with red semi-circles
43
how are stationary fronts created?
when cold and warm air masses meet and neither front advances
44
how are stationary fronts represented in weather forecasts?
a combination of alternating red semicircles and blue triangles on bottom and top
45
how are occluded fronts formed?
when a fast moving cold front overtakes a slow warm front
46
how are occluded fronts represented in weather forecasts?
alternating purple semicircles and triangles on top
47
a climate that is strongly affected by an ocean
a maritime climate

50
what is climate?
the long term average of weather conditions
51
what is weather?
