25
What is a jet stream ?
A narrow band of fast - moving, high - altitude air
26
What is the Coriolis effect ?
The apparent deflection of an object due to Earth's rotation
27
What are weather fronts ?
Air masses that interact in zones
28
What is an air mass ?
A large volume of air with uniform moisture and temperature throughout
29
How many jet streams are there in the world ?
There are four
30
How many pressure systems are there ?
There are two pressure systems
31
What is a low pressure system also known as ?
L
32
Which was does the air flow for a low pressure system ?
Counterclockwise
33
What are the results of a low pressure system ?
Causes air to rise, which results in cloud formation and precipitation
34
What is a high pressure system known as ?
H
35
What direction does a high pressure system rotate ?
Air flows clockwise
36
What is the results of a high pressure system ?
Causes the air to sink, which results in clear skies
37
What are the four types of weather fronts ?
Cold, Warm, Stationary, and Occluded Fronts
38
What is a cold front ?
Cold air forces warm air upward in a fast and chaotic manner
39
How is a cold front represented on a weather forecast ?
By Blue Triangles
40
How are warm fronts created ?
Warm air rises gently above cold air
41
How are warm fronts represented on a weather forecast ?
Red semi circles
42
How are stationary fronts created ?
Cold and warm air masses meet and neither front advances, can last for days producing clouds and prolonged precipitation
43
How are stationary fronts represented on a weather forecast ?
Red semicircles and blue triangles
44
How are occluded fronts created ?
A fast - moving cold front overtakes a slow warm front
45
How are occluded fronts represented on a weather forecast ?
Purple triangles and semi circles
46
Maritime Climate
A climate that is strongly affected by an ocean
47
Continental Climate
A climate that is not directly affected by an ocean
48
Sea Breeze
Blows from over the water toward land in the afternoon when the land is warmer than the ocean
49
What is weather ?
Are the day to day outside conditions.
